The process of project time planning
•
Irrespective of whether the project manager is
developing time, cost or quality plans, the same basic
procedure is adopted:
1.
2.
3.
4.
5.
•
evaluate the project through the Statement of Work (SOW);
generate a Work Breakdown Structure (WBS);
execute Project Logic Evaluation (PLE);
separate time, cost and quality planning;
use network analysis (CPM or PERT) to generate a Draft
Master Schedule (DFM);
This process is known as the top-down strategic
approach to project planning.
The process of project time planning
Step 1. The statement of work (SOW)
• The statement of work is the descriptive document that
defines the overall content and limits of the project.
• The SOW includes all the work that has be done in order
to complete the project. However, the project cannot be
planned or controlled at this level as it is too big. It is
necessary to break the whole down into individual
components that can be individually evaluated and
managed.
• A typical SOW contains all the information that is
required by a contractor. The level and accuracy of
information should be such that contractors or others can
price for the work to be carried out.
The statement of work (SOW)
• Typical SOW contract documents include:
– Signature block and project title.
– Definition of contract terms and scope. It summarizes the
terms and conditions used and describes the range and
extent of the works in sufficient details to identify the limits of
the project.
– Information and facilities to be provided by the client detail
the additional obligations of the client.
– Project approval requirements.
– Terms of payment and interim valuations.
– Working drawings.
– Specification.
– Schedules.
Purpose of SOW
• The main purpose of a SOW is to define
the liabilities, responsibilities and work
agreements between clients and service
providers.
• A well-written SOW will define the scope
of the engagement and Key Performance
Indicators (KPIs) for the engagement.
• Therefore, the KPIs can be used to
determine whether the service provider
has met conditions of the SOW and use it
as a baseline for future engagements.
Purpose of SOW
• SOW contains all details of non-specifications
requirements of the contractor or service
provider's effort. Whenever specifications are
involved, the references are made from SOW to
specific specification documents.
• These specification documents can be functional
requirements or non-functional requirements.
• Functional requirements define how the software
should behave functionally and non-functional
requirements detail other characteristics of the
software such as performance, security,
maintainability, configuration management, etc.
Format of SOW
1. Scope
• This section describes the work to be done
in a technical manner. If the system to be
built is a software system, this section
defines the hardware and software
requirements along with the exact work to
be done in terms of the final system.
• If there is anything 'out of scope', those
areas are also mentioned under a suitable
subheading.
Format of SOW
2. Location
• The location where the work is performed
is mentioned under this section. This
section also details the hardware and
software specifications. In addition to that,
a description about human resources and
how they work are addressed here.
Format of SOW
3. Timelines
• This defines the timeline allocated for the
projects. It includes the development time,
warranty time and maintenance time. In
addition to calendar time, the man days
(total effort) required to complete the
project is also noted.
4. Delivery schedule
• This section of the SOW describes the
deliveries and the due dates for the
deliveries.
Format of SOW
5. Standards
• The standards (internal or external) are
defined in this section. All deliveries and
work done should comply with the
standards defined in this section of the
document.
6. Acceptance Criteria
• This section defines the minimum
requirements for accepting deliverables. It
also describes the criteria used for
acceptance.
SOW is a critical document for project
management. It defines the scope of the
work and the work agreements. Therefore,
all stakeholders of the project should have a
thorough understanding of the SOW of the
project and adhere to it.
The work breakdown structure (WBS)
Level of definition of the WBS
• Most WBSs operate down to about six levels, but a
project manager should operate within whatever levels
are most appropriate.
• The number of WBS levels required increases with the
size and complexity of the project and is determined by
the need to define the tasks at a level where there are
manageable and achievable.
• Small projects may require as few as three levels,
whereas big projects may have up to six or seven levels.
• High-risk activities should be further broken down in
order to isolate the risk and plan for its mitigation.
The work breakdown structure (WBS)
•
•

•
Numbering and dividing the WBS
A logical and straightforward numbering system is required to
ensure that each task is properly coded.
Task codes can be used as unique identifiers throughout the project
for many purposes, including responsibility allocation, cost
allocation, monitoring and reporting.
The WBS element codes should be designed so as to
accommodate the cost accounting code (CAC) system that in use.
Most modern project planning and control software (f.e., the
computerized database estimating system package– CDES)
automatically generates work element codes as the WBS is
generated.
The same element code will be used in each part of the system I.e.
time, cost and quality planning and control.
As with most aspects of planning, there is no unique the only way
for preparing a WBS. The dividing of the WBS may be based on
work type, responsibility, location, etc.
The work breakdown structure (WBS)
Numbering the WBS
Step 3. Project logic evaluation (PLE)
– PLE is the process of taking the WBS work
packages that have already been identified and
showing the sequence in which they are to be
carried out.
– For time control, the project manager has to know
when each WBS activity is programmed to start and
finish. This is a prerequisite for placing orders,
committing to delivery dates, resource calculations,
etc.
– PLE is also required for cost-planning calculations
and for quality control.
– Often, there are more than one way in which the
activity could be carried out.
Project logic evaluation (PLE)
Resource over-allocation
Project logic evaluation (PLE)
• In reality, most operations are subjects to some kind of resource
limitation. This constraint applies just as much to small projects,
such as making a cup of tea, as it does to large complex projects.
• The parallel sequence of activities as shown in the previous slide is
possible, but not for a single person. The logic-driven sequence
shown is therefore dependent on additional resources.
• The resource-driven solution is clearly a different layout to the logicdriven solution. Most modern software automatically calculates
precedence diagrams using resource-driven or logic driven formats,
as input by the user.
• Resource over-allocation can be clearly identified by the
presentation of a simple bar chart, as shown in the next slide.
Project logic evaluation (PLE)
Resource over-allocation
Step 4. Separate time, cost and quality planning
• At this step, the process of planning splits depending
upon the aspect being considered:
– Project planning from the point of view of time planning and
control. Planning techniques applied specifically to time control
are known as scheduling.
– Cost estimating, planning and control. Basically, the cost
planning process consists of isolating individual cost packages
and calculating an accurate cost estimate for each one. The
individual components are then combined to produce a cost
total, usually in the form of budget plan.
– Quality planning.
Step 5. The Draft Master Schedule
• After PLE is in place, the next stage in the planning
process is networking and scheduling.
• Networking is the process of defining the project logic
in terms of the sequence of required activities, and
then assigning duration to these activities. This allows
the planner to calculate individual start and finish
times for each activity and overall project completion
date.
• Modern software allows networks to be generated
quickly and efficiently. More important, it allows
complex replanning calculations to be carried out
quickly and accurately.
• The end result of the scheduling process is the Draft
Master Schedule (DMS).
The Draft Master Schedule
• The DMS is a complete network analysis for the project, showing
start and finish time for each activity.
• The DMS also identifies the project’s critical path, namely the path
through the project that has the longest total activity duration. It is
therefore the path of activities that determines the overall project
completion date.
• Most of the activities will have some leeway (float) as to when they
start and finish, but some will not.
• Generally, the items without float in their activity windows are critical.
Any delay in these activities will delay the following activities, and if
the least are on the critical path it will result in overall project
completion delay.
The Draft Master Schedule
• The most obvious uses for a DMS are for:
– identifying an overall project completion date;
– identifying order and delivery dates for suppliers;
– identifying notification and start dates for nominated
subcontractors;
– identifying key completion dates as a basis for progress
planning;
– acting as the basis for the implementation risk management
system;
– identifying logic incompatibilities;
– use in cross-checking with subcontractor schedules;
– providing the basis for re-planning options and trade-off analysis;
The Draft Master Schedule
– providing data for the establishment of possible
consequences of delay;
– providing the data for earned value analysis;
– providing data for any necessary resource levelling.
• Scheduling involves the following primary stages:
– assign durations to each activity;
– identify the start and finish window for each activity;
– identify those activities with no window (critical path);
– re-plan as necessary;
– rationalize resources;
– form a Draft Master Schedule;
– refine the draft to form a Project Master Schedule
(PMS).

Program Evaluation and Review Technique (PERT)
•
•
•
PERT is a probabilistic approach to project planning
which was originally developed in the early 1960s
by departments within US Navy, specifically for use
on the new ballistic missiles.
PERT is event-oriented as it works on calculating
the probability of events completed within a given
time.
The basic steps involved in a PERT analysis are:
1.
2.
3.
assign three durations to each activity (optimistic, most
likely and pessimistic);
calculate activity mean duration and standard deviation;
calculate forward and backward pass values;’
The Draft Master Schedule
Program Evaluation and Review Technique (PERT)
4. identify those activities with no spare time contained within the
duration (critical path);
5. calculate project mean duration and standard deviation;
6. identify target completion date and calculate variance about
target;
7. Re-plan as necessary;
8. rationalize resources;
9. form a draft master schedule (DMS);
10. refine the draft to form a project master schedule (PMS).
The Draft Master Schedule
Program Evaluation and Review Technique (PERT)
1. Assign three durations to each activity.
- In PERT calculations, the expected time for an activity
is taken as an average of the optimistic, most likely
and pessimistic times. This average can also be
expressed in terms of an activity standard deviation.
- The expected times are used as durations on a
standard networking chart and the critical path is then
calculated as in standard CPM techniques.
- The sum of the individual durations for the critical path
can then be used to calculate a project expected time
and standard deviation.
The Draft Master Schedule
Program Evaluation and Review Technique (PERT)
2. Calculate activity mean duration and standard deviation.
– PERT durations are based on a beta distribution average. For
such a distribution the expected mean time for each activity
(a + 4m + b)
T=
6
where a = optimistic time, m = most likely time, and b =
pessimistic time.
– It is to be noted that the beta average give greatest
weighting to the most likely outcome.
– Standard deviation for each activity
S=
(b – a)
6
The Draft Master Schedule
Program Evaluation and Review Technique (PERT)
3. Calculate forward and backward pass values.
This is done in exactly the same way as under the CPM approach using
individual activity mean durations.
4. Identify those activities with no spare time contained within the
duration (critical path).
5. Calculate project mean duration and standard deviation.
Project mean duration =
Σ (all individual critical path activity mean durations)
Project standard deviation =
Σ(all individual critical path activity standard deviations)
2
The Draft Master Schedule
Program Evaluation and Review Technique (PERT)
6. Identify target completion date and calculate variance
about target.
– Either the target duration is given by the client, or the project manager
determined it himself, the project manager have to evaluate the
probability of this target actually being achieved.
– From statistical tables it can be ascertained that the mean duration will
be achieved on 50% of occasions. Remember that the beta distribution
is not symmetrical.
– To calculate the probability of achieving the target completion date the
difference between the project mean duration is converted from time
(days, weeks, etc.) to standard deviations by standardizing it. This is
done by dividing the difference by the project standard deviation.
– From statistical tables it can be found the probability of the target date
being achieved.
The Draft Master Schedule
Program Evaluation and Review Technique (PERT)
7. Re-plan as necessary.
– PERT replanning is carried out in more or less the same way as
in CPM analysis.
– Replanning in PERT involves recalculating the average and
standard deviation for each activity on the critical path each time
the analysis takes place.
– Changes in critical path activity mean duration and standard
deviation results in changes in the project mean duration and
standard deviation.
8. Rationalize resources.
9. Form a draft master schedule.
10. Refine the draft to form a project master schedule.
The steps 8, 9 and 10 are carried out in the same way as
in CPM analysis.
Project re-planning
• As soon as the DMS and PMS have been established, things
immediately begin to change.
• Change is a significant part of any project, and the planning and
control system has to be flexible enough to allow for and
incorporate change accurately.
• Project management is about optimizing time, cost and quality
performance, which are intrinsically linked. Changes in
requirements of these variables frequently occur, and the project
manager has to be able to re-plan the project accordingly.
• In practice, the most common requirement for project re-planning
calculations concerns time and cost. Clients often ask for
projects to be speeded up and need to know how much of an
increase in speed is possible and what it will cost.
Project re-planning
Crash analysis
• In crash analysis, the project manager offers re-planning advice
based on the relationships between time and cost. This of course
assumes that performance or quality criteria are fixed, as is the case
in most projects.
• Generally, a project will have clearly defined time and cost
performance at the start. This will usually be the time and cost limits
that were established as part of the statement of works and that
have been translated into contractual terms and conditions.
• The project could move to a different position in terms of time and
cost characteristics.
• If we assume that quality is fixed, then cost can be considered as a
function of time.
Project re-planning
Crash analysis
Typical time-cost curve
Project re-planning
Crash analysis
• Generally, a time-cost curve will typically have a starting point at the
agreed tender or project price. This usually represents the minimum
or near-minimum cost value and the near-optimum time value.
• In order to save time on the project, there will almost certainly be a
requirement to increase resources. This will allow the project to
finish more quickly but will result in a cost increase.
• If a project manager is looking for ways to achieve this, the most
obvious way is to find out which activity can be speeded up at least
cost, and then crash that one first, followed by the next cheapest,
and so on. This will result in the typical negative time-cost curve.
Project re-planning
Crash analysis
• This curve will rich a point where all critical-path activities have been
speeded up as far as possible.
• Beyond this point, no further time can be saved on the project. Any
further crashing will result in cost increase, and no further time will
be saved.
• There is no point in crashing any non-critical activities, as this will
simply increase costs while giving no time saving.
• As critical path items are crashed, the overall length of the critical
path will reduce.In most cases, this means that at some point the
original critical path will no longer be critical. It is therefore important
that the critical path is checked after each crash to ensure that it is
still critical.
Project re-planning
Crash analysis
• If a parallel path becomes critical before the crash limit has been
reached, then the process has to be repeated so that a new critical
path can be identified.
• In some cases, two critical paths may appear. It now becomes
necessary to crash both critical paths at the same time. This
involves identifying those activities on each critical path that have
the lowest cost of crashing per unit time and then crashing them
simultaneously.
• Once any critical path becomes fully crashed, that is the end of the
process.
• The classical time-cost curve is one example of a trade-off analysis
which is widely used in project management.
Trade-off analysis
Methodology for trade-off analysis
1. Identify the reason for the problem.
Trade-offs can occur both before and during the
execution of the project.
Typical reasons for pre-execution trade-offs are:
– changes in client requirements (particularly changes in
the required scope of work and cost limits);
– discovered design incompatibilities;
– changes imposed by subcontractors and suppliers;
– misunderstanding resulting from pure communications;
– unforeseen problems such as sudden non-availability of
important materials;
– Changes in organizational strategic objectives (generally
resulting from external imposed change)
Trade-off analysis
Methodology for trade-off analysis
• Typical reasons for execution trade-offs:
– changes in client requirements (particularly additional required
work);
– discovered human error (such as inaccurate time estimating);
– discovered execution problems (such as unforeseen work
complications);
– emerging risk (such as inaccurately assessed risk);
– project-specific events (such as mechanical failure or unforeseen
conditions).
• It is imperative that the reason for the problem is
identified and some kind of control system put in place to
avoid or control the occurrence of the same problem in
future.
Trade-off analysis
Methodology for trade-off analysis
2. Reevaluate the project objectives.
Imposed change may result from changes in the project
status and environment.
– Typical reasons for a relative change in project status
resulting from a change in organizational strategy include:
–
–
–
–
–
–
–
changes in competitor behavior;
changes in customer demand;
changes in the national and global economy;
changes in strategic leadership and emphasis;
changes in available technology;
the introduction of new codes of practice;
the introduction of new legislation.
Any of these changes could result in the formulation of new
strategic objectives, which in turn result in the original project
objectives becoming misaligned.

3. Allow for any other relevant factors. Typical examples
include:
–
–
–
–
–
–
–
a deterioration in industrials relations within the company;
weather conditions (where relevant);
exchange rates (where relevant);
mechanical failure and breakdown;
discovered errors or omissions in the contract
documentation;
resource availability problems;
consultant problems.
4. Assemble a shortlist of solution scenarios.
5. Select and test the best alternative.
6. Implement the best (or approved) alternative.
The PCCS planning cycle
Developing estimate accuracy
The PCCS planning cycle
Project estimating
• Cost estimations are prepared first and foremost to calculate the
sales price, but they are generally needed on all projects to provide
valuable input into a whole host of other management activities:
–
–
–
–
–
–
–
milestone planning;
valuing the likely cost of change notices and variation orders;
periodically reviewing the likely final account total;
assisting in cost control;
assisting in trade-off analysis;
assisting in performance monitoring;
assisting in establishing productivity targets as a basis for bonus
payments.
Project estimating
Top-down estimating
• Top-down estimating is very common and involves senior
management setting the overall project budget. They do this by
estimating the overall project costs on the basis of their experience,
knowledge and accessible project data.
• These estimates are often fixed and then handed down to lower-level
managers to break down the costs to individual activity and work
packages level.
• The benefits of top-down estimating:
– the budget is set by senior management and is therefore compatible with
the overall strategic objectives of the organization;
– the budget carries more authority since it originates from senior
management;
– the budget is less likely to be changed or tampered with during the
course of the project;
– any such changes are likely to be formalized;
Project estimating
Top-down estimating
– because the estimate originates from higher levels within the
organization, it is likely to be more reliable and accurate;
– local influence and bias are unlikely to be factors.
• The disadvantages are that:
– the project team may feel that unrealistic budgets have been
imposed upon them;
– where great incompatibilities are perceived there may be a
reduction in project team motivation;
– the senior management may be “out of touch” with operational
costs;
– politics may be a factor. Some element or package managers
may receive a greater budget for “specially” reasons.
– the inappropriate budget allocation can affect the entire cost
control and performance management systems.
Project estimating
Bottom-up estimating
• The project budget being developed upwards from the
individual activity level.
• Each activity is estimated as accurately as possible in
terms of labor hours, materials and equipment required
to complete the task.
• These estimates are then converted into a financial cost
estimate.
• The resulting tusk budgets are then aggregated to give
the total direct costs of the project.
• The project manager or senior manager will then add
indirect costs, any contingencies and a profit figure, to
arrive at the total project budget.
Project estimating
Bottom-up estimating
• The advantages of the bottom-up estimating are that:
– the people “on the ground” decide on what is required and on
how much it should cost;
– the people are more likely to commit themselves when they have
had a say in setting their own budgets;
– the people who set their own budgets are more likely to stick to
them;
– provided budgets are allocated fairly, this eliminates the
motivational problems associated with favouritism or other forms
of inequitable budget allocation.
• The disadvantages are that:
– the budgets may carry less status than those set by senior
management;
Project estimating
Bottom-up estimating
– careful controls are needed to ensure that budgets are not
altered;
– local influence and bias may be issues;
– it may be difficult to adjust budgets in line with strategic changes;
– the budgets are more easily overridden by senior management;
– senior managers sometimes feel threatened;
– element and package managers tend to overestimate to “be on
the safe side”;
– the whole project budget can become driven by the process itself
rather than by market conditions.
Project estimating
Iterative estimating
• Iterative estimating is based on negotiation and represents a
compromise between top-down and bottom-up estimating.
• Element and package managers develop detailed action plans and
corresponding estimates for the work which they are responsible for.
They then present these plans and estimates to senior management
for approval.
• Operational managers and senior managers negotiate on the action
plans and estimates, and some re-definition and refining occur.
• The end result should be an action plan and estimate that lies
somewhere between the market-driven conservative estimate of the
senior management and the process-driven generous estimate of
the operational manager.
Project estimating
Iterative estimating
• Advantages of the iterative estimating:
– the estimate is prepared by the operational manager;
– the estimate is tempered by senior management and is therefore more
likely to be compatible with the strategic objectives of the organization;
– the influence of market forces is maintained;
– the end result combines practical (operational) considerations with
senior management (strategic) considerations.
• Disadvantages:
– the negotiation process is time consuming and costly;
– adequate control procedures have to be put in place to prevent the
senior managers simply overriding the operational managers;
– some operational managers might be better at negotiation than others
and may secure themselves a better budget total than their less gifted
colleagues;
– negotiation skills can become more important than estimating skills.
Project estimating
Bidding strategy and estimate reporting
•
•
In the case of an internal project management
system, once the project or work package has been
approved in principle, the next stage is to prepare the
bid for approval by senior management.
In most cases, the developing of the bid progresses
to eight stages:
1.
2.
3.
4.
5.
6.
7.
8.
Formulate a viable estimating strategy.
Make initial (order of magnitude) minimum realistic estimate.
Carry out any necessary preliminary refinement.
Make realistic (indicative) minimum estimate.
Add for profit and risk.
Compare overall price to projected cost limit.
Make subjective evaluation of bid success probability.
Develop final (definitive) estimate.
Project estimating
Computerized database estimating systems (CDES)
• The CDES works by linking together several different databases.
Each database contains a different type of information:
– The description library. It is a collection of standard descriptions. The
descriptions are arranged in an hierarchical format, where each item of
work is broken down into more and more detail until a level of detail is
arrived at where accurate pricing can occur. Different databases are
available for different industries.
– The price code and unit rate databases. For each description, the price
code database has a record of what individual components are included
within the description. For every library description, there is pre-set list
of labour, equipment and material, together with time allowances and
unit costs.
– Other database elements.
Computerized database estimating systems
• Computerized database estimating systems (CDES) are
used during the estimate measurement process.
• In manufacturing/engineering/construction projects,
drawing information is transcribed directly into the CDES
either by manual measurement or by scanning directly
from drawings using a digitizer. The CDES then stores
an electronic version of the drawing data and builds up
an automatic electronic budget plan.

Основой для составления плана платежей обычно является план

платежей совпадает по сумме и времени с издержками.
При внешних проектах особое значение имеет характер соглашения о
платежах. Чем больше размер аванса и чем чаще осуществляется
оплата за выполненные объемы работ, тем у исполнителя меньше
проблем с сохранением ликвидности и меньше риск в случае
прекращения проекта.

The project budget plan
• The project budget is the end result of the planning phase. It is the
sum total of all individual work package budgets for the whole
project.
• The project budget is therefore the estimated cost for the whole
project. It comprises a whole series of sub-budgets for individual
WBS work packages. The project budget WBS is normally identical
to the project WBS that is developed during the planning phase of
the project life cycle. It is developed to a level where a pre-tender
cost check is performed before contract documents are issued to
prospective tenderers.
• The project budget is not the same as the selling price, or even the
tender price. The project budget is the effective cost limit as
authorized and set by the client.
• The final or baseline budget plan are the end result of a series of
internal estimate planning processes, tempered by the external
influences of tenderers who are usually free to price the same works
in any way that they wish.
The project budget plan
The project budget plan
• At it most basic level, the project budget relates the forecast costs to
particular project task. It also considered to be a management,
planning and decision-making tool, that may be used for:
– establishing the overall budget baseline for the project. This baseline acts
as the basis for subsequent earned value analysis;
– developing (in association with the project schedule) the projected cost
curves for each element and work package;
– establishing a reference for variance analysis allowing the performance of
individual elements and packages to be assessed throughout the course
of the project;
– moderating the spending of element and package managers;
– generating the basic data for scenario analysis in trade-offs;
– estimating the likely effects of change notices and variation orders.
The project budget plan
Budget development and layout
• To be an effective management tool, the project budget should
contain at least:
– project objectives and activities in terms of measurable outputs;
– the financial resources allocated to achieve these objectives and
complete the activities;
– clearly defined start and finish points of each activity;
– the facility to compare actual and planned performance details.
• Perhaps the most important aspect of the budget is the cost-coding
format. For accurate monitoring and control, it is essential that each
element of the budget corresponds to an identifiable and
measurable work package and that the budget element and its
associated work package must share a common, unique cost code.

• Preliminary costs are those that are considered to be general project
overheads.
• Prime cost sums are those where the work is to be subject to a
nominated or named subcontractor.
• Provisional sums are those where the exact extent of the works is
not known and an exact cost estimate cannot be produced. A
provisional sum is included to cover the likely extent of the works.
• Direct payments are payments made through the project, but made
to organizations that are not part of the actual project team.
• Dayworks are generally included to allow for unforeseen and
unmeasurable works, which might nevertheless arise.
• Typical overall additions would include allowances for
contingencies, fees and taxes.

• The final requirement for completion of the baseline
budget plan is to calculate some form of expenditure
profile for the project. This is normally performed by
relating the CAC sums to the project draft master
schedule (DMS).
• Modern project planning and control software does this
automatically.
• The start and finish dates for each activity are used to
show the start and the finish expenditure dates for each
CAC element. By knowing the spend duration and the
spend curve characteristics of each activity, it is possible
to calculate a spend profile for each package and for rollup elements at each level higher in the WBS.

Budget development and layout
The project budget plan
Budget changes
• Budgets are generally not static, particularly in large projects where
the exact scope of work is difficult to define precisely at the outset.
They change throughout the life cycle of the project, and with every
agreed project-scope variation (or change order) there is an
associated variation in cost that has to be budgeted for. The budget
should therefore be prepared in a manner in which changes are easy
to accommodate.
• At any time during a project, its budget should be transparent enough
to identify the original budget, the cost associated with approved
change orders, and the total current budget.
• It is clearly important that budget changes are controlled in some
way. Large project typically include some kind of change control
section (CCS). The CCS is responsible for monitoring all change on
the project and for predicting the implications of change requests
before authorizing them.
• On large projects, changes to the project budget are often formalized
through the issue of a cost account variation notice (CAVN).
The project budget plan
• Most changes to project budgets are necessitated by the issue of
change notices. These are variation orders that are issued by the
project manager or design team members. The effect of the
change notice is a modification of the project’s work
requirements. This may be necessary for a number of reasons.
The most obvious ones are work items that have been
overlooked during the design stage, unforeseen complications
and additional works, and changes in client preferences and
requirements.
• Change orders often provide an excellent opportunity for the
contractors and suppliers to make a healthy profit. The project
team is “locked in” and the selling price for a change order is not
normally constrained by normal market forces. Often, but most
particularly when work is scarce, companies will take on projects
at little or no profit margin, in the hope that there will be scope
changes during project execution period where they can
increase the sales price and realize a healthy return.

Перепланирование проекта
• Как только первичное планирование заканчивается
(а часто и ранее), ситуация начинает меняться.
• Изменения являются характерной чертой проектов,
поэтому система их планирования и контроля
должна быть гибкой, чтобы адекватно учитывать
изменения.
• Управление проектом предусматривает оптимизацию
соотношения времени, стоимости и качества.
Требования по изменению одной из этих переменных
возникают часто и руководитель проекта должен
быть в состоянии оперативно перепланировать
проект.
• Заказчики часто просят ускорить ход проекта.
Необходимо показать им насколько это возможно и
сколько это стоит.

Управление проектом/контроллинг
проекта . Задачи контроллинга
Понятие «контроллинг» происходит
от английского «to control», что означает
управлять, распоряжаться, контролировать,
регулировать, проверять, настраивать,
обусловливать, нормировать.
Задачи контроллинга явно выходят
за пределы чистого контроля.
Контроллинг должен обеспечить
достижение цели проекта.

Задача сравнения планового и

Задача контроллинга - зафиксировать отклонения в сроках,
издержках, мощностях и ходе выполнения проекта путем
сравнения планового и фактического состояния дел и привлечь
внимание руководства проекта к необходимости принять
необходимые встречные меры или откорректировать планы.
Для сравнения фактического и планового состояния дел и
установления отклонений важно, чтобы фактическое состояние могло
быть четко приурочено к определенному моменту времени. В противном
случае можно прийти к ошибочным выводам.
Далее производится анализ причин отклонений и
выясняется повлияют ли эти причины на дальнейший ход проекта.
Центр тяжести анализа причин отклонений ориентирован
на будущее проекта и его цели и меньше всего является средством
для поиска виновников.

Вехи представляют собой показатели для краткосрочных целей,
упрощающих измерение продвижения (достижений) проекта на
протяжении всего периода его выполнения, а не только в конце его.
Они указывают также на время, когда могут приниматься решения.
Анализ тренда вех показывает в данный момент времени
прогноз сроков окончания отдельных работ.
Пример:
На следующем слайде для обоих рабочих пакетов 1 и 2 в таблице

Контроль издержек
Составляющие контроля издержек:
-система обратной связи, позволяющая
зафиксировать фактическое состояние дел,
- сравнение фактического состояния с плановым,
- анализ отклонений.
Реалистичный контроль издержек возможен только в том
случае, если регистрация фактических издержек
осуществляется в соответствии с их плановой
классификацией. Для этого нужно на стадии планирования
рассматривать отдельные рабочие пакеты как носители
издержек нижнего уровня. В этом случае они несут в себе
не только сроки, но и затраты материальных и человеческих
ресурсов, оценка которых дает и соответствующие им
издержки.

Превышение сроков и издержек
в проектах
Значительные превышения сроков и издержек в проектах это явления,
которые известны уже тысячелетия. Д. Элтон и Ю. Рой пишут:
«Сколько проектов в вашей организации были завершены вовремя и
уложились в бюджет? Большинство менеджеров ответят вам – ни один.
И это вопреки использованию программных инструментов управления
проектами, технологии менеджмента, систем управления данными,
программ тренинга команд и использованию «лучшего опыта». Каждый
менеджер имеет оправдания, почему данный проект удался плохо, но
попытки предусмотреть впредь неожиданные проблемы редко имеют
успех».
Классическим примером является здание оперы в Сиднее, где
издержки на строительство превысили смету в 16 раз.
Превышение сроков и издержек
в проектах
Особенно ярко проявляется этот эффект в проектах внедрения
информационных технологий. При этом проблемы остаются
нераспознанными в течение длительного времени. Так в 1992 г.
Социальный департамент Калифорнии начал проект создания
автоматизированной системы штата по поддержке детей. Был заключен
контракт с фирмой на $75,5 млн. на три года. К 1995 г. расходы
незавершенного проекта достигли $260 миллионов. Проект был все же
продолжен и только в 1997 году он был прекращен после пятилетней
работы. При этом общие издержки достигли $345 миллионов.
Меры для улучшения положения с
соблюдением издержек и сроков проектов
• совершенствование методов оценки,
• развитие современных процедур оценки, при
которых назывались бы не только конечный
срок и расчетная суммарная стоимость, но и
представлялась бы
соответствующая
детализация, а также информация о степени
достоверности и качестве единичных оценок,
• улучшение качества менеджмента.
Существенным шагом в этом направлении является
строгое соблюдение последовательности
выполнения проекта в соответствии с принятыми
фазами проекта.

Проблема оценки истинного состояния
проекта в отношении издержек и
выполненного объема работ
• В больших проектах несинхронность оплаты и
выполнения работ может сильно искажать оценку
истинного состояния проекта (по стоимости и
срокам).
• Одним из методов оценки истинного состояния
проекта является метод анализа заработанной
стоимости.
• Однако и он не может учесть всего многообразия
причин задержки и опережения платежей по
сравнению с выполненным объемом работ, но может
служить предупредительным сигналом для
проведения более детального анализа.
The PCCS operating cycle
• The operating cycle, sometimes referred to as the cost
and control system, is the section of the PCCS that
implements the estimating and budgeting sections of the
planning cycle.
• The operating cycle authorizes commencement of the
priced works and monitors the actual expenditure
against planned expenditure in order to generate cost
variances.
• The PCCS operating cycle comprises four phases:
–
–
–
–
Phase 2: work initiation;
Phase 3: cost data collection;
Phase 4: generation of variances;
Phase 5: cost reporting.
The PCCS operating cycle
Phase 2: work initiation
• In order to be able to control costs, there must be some
form of controlled release of work.
• This could be done through the formal issue of a
contract, or through control change control notices such
as variation orders or works orders.
• The project works order (PWO) would typically describe
the work, and any standards to be adhered to, and
identify the cost center to be charged. This is usually
done through some system of cost accounting codes
(CAC). The cost accounting codes system is usually
based on the project WBS.
The PCCS operating cycle
Phase 3: cost data collection
• PCCS cost-data collection and reporting use earned value analysis
(EVA). EVA is simply a way of comparing actual with target figures
for performance and cost.
• EVA uses variance analysis as the basis for its calculation. Variance
analysis is centered on two variances, cost variance and schedule
variance.
• EVA is based historically on milestone monitoring. A milestone
represents a definite stage in the project and is an appropriate point
at which to measure performance.
• Milestone monitoring is most suitable for use when plans and
schedules are not particularly detailed. It is a simple tool, but as with
any simple technique, it does have a number of disadvantages.
The PCCS operating cycle
Phase 3: cost data collection
The PCCS operating cycle
Phase 3: cost data collection
The PCCS operating cycle
Phase 3: cost data collection
• Milestone monitoring has a number of disadvantages:
– Reaction time lag. A milestone report could indicate a cost
variance that originated in an element several months
previously and it could be to late to fully correct whatever
caused the variance.
– Residual accumulated overspend. Even if the ongoing
expenditure are brought back into line, the accumulated over
spend will remain.
– Re-planning issues. Milestone programs are very susceptible to
re-planning and trade-offs.
– Time scale issues. Milestones represent conditions at a
particular point in time rather than along a time continuum. This
is a limitation as the project is dynamic. Milestones do not allow
for work in progress.
The PCCS operating cycle
Phase 3: cost data collection
• EVA is a type of milestone monitoring applied
specifically to determine cost and schedule variances
for component sections of a project. EVA is an
attractive method of project control because it:
– is dynamic;
– provides combined and simultaneous time- and costperformance assessment;
– provides frequent reporting; a good system allows daily
reporting, if required;
– demonstrates value as well as cost. It therefore gives a high
frequency report on profitability;
– generates accurate assessment of the cost implication of
delays;
– allows easier trade-off analysis in that the calculations include
resource implications.
The PCCS operating cycle
Phase 3: cost data collection
• The cost variance is the difference between the budgeted cost of the
works and the actual cost. For both budgeted and actual costs, the
value is taken in terms of the works actually completed or
performed.
• Variances can be expressed in terms of measurable effort and
support effort.
• Measurable effort relates to separate elements of work that are set
within a defined schedule for accomplishment. Completion of the
effort produces tangible results.
• Support effort relates to project actions where it is difficult to isolate
it into measurable units. Examples would include project support
and administrative services.
• Variance analysis is designed to show how different parts of the
budget plan are performing at any one time.
The PCCS operating cycle
Phase 3: cost data collection
• There are seven major considerations involved in
variance analysis:
–
–
–
–
–
Identify and validate the variance.
Quantify the variance.
Determine the source of the variance.
Determine the impact of the variance on the project as a whole.
Determine the impact of the variance on other elements and
packages.
– Determine the extent to which tactical response is already
underway.
– Determine the range of possible outcomes of any corrective
action.
The PCCS operating cycle
Phase 3: cost data collection
Example of variance analysis
The PCCS operating cycle
• On the tasks that are 100% complete, the earned
value is equal to the original budget, irrespective of
the costs actually incurred on that task. If Task A in
our example is complete, then the earned value of the
work done on Task A is $5100 despite the fact that
$5200 was spent in achieving this earned value.
• The table shows that the project is ahead of budget, but
the position is a little better, because the $700 over
budget include some work done on the Task G, that was
not foreseen at the end of month 3.
The PCCS operating cycle
Phase 3: cost data collection
• Earned value analysis makes use of following variables:
– Actual cost of the works performed (ACWP);
– Budgeted cost of the works performed (BCWP)/ (actual earned
value);
– Budgeted cost of the works scheduled (BCWS) /(planned earned
value);
– Scheduled time for work performed (STWP);
– Actual time for work performed (ATWP);
– Cost variance (CV);
– Schedule variance (SV);
– Budget at completion (BAC) /(project baseline);
– Estimate at completion (EAC);
– Variance at completion (VAC).
The PCCS operating cycle
Phase 3: cost data collection
The PCCS operating cycle
Phase 3: cost data collection
Estimate at completion (EAC).
– The estimate at completion is the estimated total cost of the project. It is
the sum of all direct and indirect costs to date plus authorized work
remaining:
EAC = ACWP + estimate to complete (ETC), and this is the updated
estimate of the total project cost.
– This approach is sometimes known as the planned estimate approach. The
planned estimate approach is simplistic in that it assumes that the current
underspend or overspend will continue for the remainder of the project.
– The EAC can also be expressed in terms of the budget at completion:
EAC = BAC – CV.
– EAC can also be expressed in terms of the cost variance index (CVI):
EAC = (ACWP/BCWP) x BAC
– This approach is sometimes referred to as the current estimate approach.
It is less simplistic than the planned estimate approach as it uses BAC
rather than EAC. As such it includes an estimated value for the anticipated
remaining work content rather than the original estimate of the cost to
complete the remaining work.
The PCCS operating cycle
Phase 3: cost data collection
• Variance at completion (VAC).
The variance at completion is the difference between
what the project should have cost (BAC) and what it is
expected to actually cost (EAC): VAC = BAC – EAC.
• For example:
CV = BCWP – ACWP = $75000 - $90000 = - $15000 (i.e. a cost overrun of $15000)
SV = BCWP – BCWS = $75000 - $50000 = $25000 (I.e. ahead of schedule by
$25000)
TV = STWP – ATWP = 3 months – 2 months = 1 month (I.e. one month ahead of
time schedule)
CV ratio = BCWP/ACWP = 75000/90000 = 0.83
SV ratio = BCWP/BCWS = 75000/50000 = 1.5
TV ratio = STWP/ATWP = 3 : 2 = 1.5
• Underperformance is indicated by a ratio less than one unity which confirms in
the current example, that cost running above budget.

work package. Most work packages will go on to exhibit the curved shape
shown in the next slide.

Phase 3: cost data collection
• Multilevel earned value analysis.
– Another advantage of EVA is the ability to develop multilevel variance
summaries for different levels in the project. In order to do this
effectively, the EVA system has to work in conjunction with a CDES
(Computerized database estimating systems ).
– Using a CDES, the original budget plan is primed with budgeted cost
(BC) values. These values remain constant throughout the life cycle,
except where official changes are made through the CAC (cost
accounting codes) change control system. The ACWP values for each
cost center are automatically charged to that cost center by accounting
control or through whichever section is responsible for setting invoices
and paying salaries. The work scheduled (WS) figures are stored in the
project schedule and can be automatically linked to the CAC network for
the project.
The PCCS operating cycle
Phase 3: cost data collection
– Linking the CDES, DMS and payment records allows BCWP, BCWS
and ACWP to be automatically calculated at different levels through
the project, thus allowing the development of a roll-up analysis. The
sum total of all the costs and schedule variances on a particular level
form the total at the next level for the collective work element.
The PCCS operating cycle
Phase 3: cost data collection
The PCCS operating cycle
Phase 4: generation of variances
Variance and variation envelope.
A variance is any cost or schedule deviation from a
specific and predetermined plan. Permitted variances
are usually larger in the early stages of a project
becoming smaller as the project progresses.
• The variance envelope defines the limits of acceptable
performance around the mean, beyond which some kind of alarm
bells should start to sound.
• Analysis of this variance envelope is one of the main applications
for the monitoring and control aspects of EVA. The values for CV
and SV can be used together to show the cost and schedule
performance of any individual WBS element and also for groups of
elements using a roll-up analysis.
• The variance generation process involves looking at CV and SV in
order to assess the performance of individual work packages and
groups of work packages.
The PCCS operating cycle
Phase 4: generation of variances
• Variance interpretation.
– Cost variance CV = BCWP – ACWP
Therefore
BCVP > ACWP: work performed has cost less.
BCWP < ACWP: work performed has cost more.
BCWP = ACWP: work on cost plan.
– Schedule variance SV = BCWP – BCWS
Therefore
BCWP > BCWS: work ahead of program.
BCWP < BCWS: work behind program.
BCWP = BCWS: work on program.
The PCCS operating cycle
Phase 4: generation of variances
– These values can also be shown as indices.
– Cost Variant Index CVI = BCWP/ACWP
CVI > 1.0: good; CVI < 1.0: bad; CVI = 1.0: OK.
– Schedule Variance Index SVI = BCWP/BCWS
SVI > 1.0: good; SVI < 1.0: bad;
SVI = 1.0: OK.
• There are several different ways of interpreting cost and schedule
variance figures, and immediate appearances might not always be a
true reflection of the situation.
• Example interpretations could be as follows:
The PCCS operating cycle
Phase 4: generation of variances
•
•
•
•
•
•
•
•
•
CVI > 1.0, SVI > 1.0. Excellent: the project is under cost and ahead on
program.
CVI > 1.0, SVI =1.0. Good: the project is under cost and is on schedule.
CVI > 1.0, SVI < 1.0. Good/bad: the project is under cost but behind on
program.
CVI =1.0, SVI > 1.0. Good: the project is on cost and ahead program.
CVI = 1.0, SVI =1.0. Good: this scenario means that the project is on cost
and on schedule.
CVI = 1.0, SVI < 1.0. Bad: the project is on cost but is behind schedule.
CVI < 1.0, SVI > 1.0. Good: the costs are over the projection, but the project
is also ahead of program.
CVI < 1.0, SVI = 1.0. Poor: the project has a cost overrun and is on
program.
CVI < 1.0, SVI < 1.0. Very bad.

The indices can be used as a direct indicator of performance by showing
them against axes ranging from zero to unity.

• The critical ratio uses EVA principles in that it includes consideration
of both time and cost performance.
• The critical ratio is also useful in that the project manager can apply
relative weightings to the time and cost elements. F.e., time may be
more important than cost on a given project. Multiplying the time
element, for example by 0.5, effectively amplifies the importance of
the time element relative to cost. Actual progress has to be twice as
great for a time value of unity to be obtained.
• Critical ratio are often shown as diagrams.
The PCCS operating cycle
Phase 4: generation of variances
Typical zone classification are listed
below:
• Zone A: Take no action. The lower limit for this zone is established at
the outset.
• Zone B: Record and monitor. This zone contains more significant
negative variations that cannot be ignored. The negative variation may
not be regarded as critical but any variations that continue to move
downwards may be a cause for concern.
• Zone C: Act immediately. Immediate variance analysis and corrective
trade-offs are required.
• Zone D: Emergency response required. These variances are supercritical.
• Zone A1: Observe and note. Activities that fall into this zone could be
useful for feedback and for involvement in change notices.
• Zone A2: Investigate and correct. This zone contains activities with
large positive variances. It should not be possible for an activity to
reach this zone so there is clearly a problem. Typical reasons include
pessimistic estimating, poor quality control, poor supervision,
undetected errors and omissions.
The PCCS operating cycle
Phase 5: cost reporting
• Reporting is the first step towards monitoring, analyzing
and ultimately managing the progress of any project.
• Good-quality information is the key to good project
decision making and therefore good project
management.
• The quality and nature of the project reporting system
will directly influence the quality, appropriateness, and
timeliness of the information provided to managers and
upon which they will base their decisions.
The PCCS operating cycle
Phase 5: cost reporting
• In general reports should:
– be produced on time;
– include only relevant information;
– allow for all interrelationships between the data contained in
them;’
– be honest and accurate;
– be issued to everybody who is involved;
– highlight particularly important issues;
– put forward proposed solutions (where appropriate);
– put forward clear responsibilities and time scales for
implementation (where appropriate).
The PCCS operating cycle
Phase 5: cost reporting
• When used properly reports can be extremely useful.
Timely well-written reports can:
– improve the overall understanding and efficiency of the project
team;
– provide early warning of potential problems;
– act as an overall stabilizing mechanism;
– contribute to the project audit trail;
– provide essential data to act as the basis for management
decision making;
– assist in progress reviews;
– improve coordination of management response.
The PCCS operating cycle
Phase 5: cost reporting
• Basic report types:
– Routine reports are issued routinely. These are used primarily to keep
team members up to date on the everyday performance of the project.
Routine reports tend to be specific: cost reports, schedule progress
reports, quality reports, risk reports. Large projects tend to have review
meetings.
– Development review reports are used where the project team is
undergoing any kind of development program or where the project itself
is subject to review. This type of report is typical on research and
development projects where the precise work content is not known at
the outset.
– Exception reports are issued primarily to highlight an exception where
something has occurred that is out of the ordinary.
– Subject specific reports are produced where a specific aspect of the
project is causing concern and where detailed monitoring and control is
required.
– Project variance and analysis report (PVAR) combine the approaches
listed above.
The PCCS operating cycle
Phase 5: cost reporting
• PVAR reporting use EVA as the primary analysis tool.
– A PVAR report is generated directly from cost data and would
normally be assembled each month.
– The report shows the variance performance of the project as a
whole and then moves down to finer levels of detail according to
the WBS breakdown used by the CDES.
– The PVAR report itself would typically show:
• routine reporting information;
• development progress and review information;
• the performance of each level of the WBS in terms of: ACWP,
BCWP, BCWS, CV, SV, EAC, ETC.
• any significant cost or schedule variances;
• sources and reasons of such variances;
• proposal responses together with individual responsibilities, action
plans and time scales.
The PCCS operating cycle
Phase 5: cost reporting
• For each problem cost center, separate PVAR reports
are generated showing:
– WBS identifiers (project, elements, sub-elements etc.);
– CAC identifier and approved budget limits;
– current values of ACWP, BCWP, BCWS, CV, SV, BAC, EAC,
ETC and VAC figures;
– previous month (or other reporting period) corresponding
values;
– summary of differences between previous month and current
month values;
– summary of significant differences (improvements and
deteriorations);
– current EAC, ETC, ECTC, ETTC values.
• The PVAR report would probably show the curves
given in the next slide.
Анализ заработанной стоимости (Earned Value Analysis)
The PCCS operating cycle
Phase 5: cost reporting
• Once the value in terms of performance variables has been
established for every task, the only input required to make the
system work is the approximation of works completed. Once this has
been input, the EVA system can quickly and easily calculate the
following parameters:
– Earned value is the money that has been earned by doing the work to
date. It is equivalent to the budget cost of the work multiplied by the
amount of work completed and valued.
– Earned value hours are the total budgeted number of hours multiplied by
the proportion of total hours actually completed. This shows the
proportion of earned value that has already been achieved and gives an
indication of the proportion that remains.
– Anticipated final hours are the total budgeted number of hours divided by
the proportion of total hours actually completed.
– Project efficiency is the earned value hours divided by the total hours
actually completed.
– Project progress is the earned value hours divides by the total budgeted
work hours.

Реальность планирования
Часто в начале проекта легкомысленно
подходят к оценке продолжительности
работ и принимают обязательства,
которые потом не могут быть
выдержаны.
Как слишком завышенные,
так и заниженные задания приводят
к повышению издержек, а
недоверие к реальности планирования
приводит к отсутствию
дисциплины.
Если опыт показывает, что планы
нереальны, то им больше не верят и
игнорируют.

Project Risk Management
Introduction
• Projects tend to be complex and one-off. They may operate within
an environment that is characterized by uncertainty.
• The project manager has to make decisions under conditions where
risk is an everyday factor.
• The project manager has to be able to analyze the project and its
environment, and identify the risks that are present.
• The project manager has to be able to transfer or reduce
unacceptable risks and then set up monitoring and control systems
so that residual risk can be managed effectively.
Background to risk
The concept of risk
•
•
•
•
Risk and opportunity go hand in hand. Everybody is
on the lookout for a good opportunity.
Opportunities exist within an uncertain world and are
therefore subject to uncertainty and risk. In order to
succeed, companies have to take risks. The relevant
risks have to be effectively managed if opportunities
are to be exploited.
Risk and risk management should not be seen static.
Risk is therefore both a good thing and a bad thing. It
is a driving force behind innovation and enterprise,
but it also a threat if not properly evaluated and
managed.
Background to risk
The concept of risk
• In general terms, the decision maker acting under
conditions of risk would be most concerned with the
following questions:
–
–
–
–
What can go wrong with the project?
What possible outcomes do we face as a result of these risks?
Where do these risks and consequent outcomes originate?
Do we have any control over these risks and if so are we using
it?
– Are the risks and consequent outcomes related to any extent?
– What is the degree of exposure of the organization to these
risks?
– How sensitive is the organization to each degree of exposure?
Background to risk
The concept of risk
– Do this risks affect the achievement of the overall strategic
objectives of the organization?
– What response options do we have?
– What contingencies or emergency responses are in place?
– Can we match the worst case scenario?
– If not which scenario riches the limit of our response abilities?
– What is the potential reward associated with each risk?
– Are we prepared to accept a risk and corresponding outcome
that is beyond our limits to absorb?
Виды рисков
Суммарный риск проекта содержит в
общем случае четыре больших
группы рисков:
-
технические риски;
-
экономические риски;
-
политические риски;
-
социокультурные риски.
Наиболее частым источником рисков являются стыки. Успешное
наведение мостиков в местах стыков различных частей системы
является одной из важнейших задач проекта.
Технические риски
Источниками технических рисков являются
инженерные ошибки, дефекты поставки сырья и
материалов, ошибке при изготовлении, монтаже и
сдаче в эксплуатацию.
Примером инженерной ошибки может быть
неудовлетворительное проектирование, из-за которого не
достигается запланированная производительность установки или
не соблюдены действующие в стране потребителя законы, нормы и
правила.
Под дефектами поставки сырья и материалов
понимают ситуации, когда не соответствует требованиям проекта
их качество или количество, а также, если они поставляются с
опозданием.
Технические риски
Риски при изготовлении, монтаже и сдаче
в эксплуатацию связаны, главным образом, с
квалификацией персонала и поэтому их особо трудно
оценить.
Риски могут также возникнуть и потому, что в
других климатических или географических условиях
известные приборы, установки или технологии
реагируют неожиданным образом. Нередко имеет место
и ситуация, когда в месте монтажа своевременно не
подготовлена площадка или подъездные пути,
отсутствуют необходимое сырье, материалы или их
качество и количество не соответствует нуждам проекта
и т.д
Одним из важнейших факторов риска, особенно в
условиях Сибири, является климат.
Экономические риски
•
В группу экономических рисков входят:
1. Финансовые риски.
2. Риски взаимодействия с клиентами.
3. Риски взаимодействия с партнерами по
кооперации и поставщиками.
4. Риски в управлении проектом.
5. Информационные риски.
6. Риски, связанные с отсутствием
квалифицированной рабочей силы.
Особенно важны риски, связанные с финансированием
проекта – платит заказчик согласованные суммы аккуратно
или нет, темп инфляции, курс валюты и др.
Экономические риски
Риски взаимодействия с клиентами, партнерами по кооперации и
поставщиками связаны обычно с пробелами в договорах или плохо
разграниченных позициях договоров.
Если договор выполняется за рубежом, то возникает дополнительный
риск, связанный с проблемой нахождения квалифицированного
руководства проекта на весь период выполнения работ. Может
возникнуть и целый пакет проблем, связанных с недостаточной
коммуникацией и информацией, например, языковые проблемы,
отсутствие или низкое качество связи между местом работы и
материнской организацией. В отдаленных районах и за рубежом могут
возникнуть дополнительные проблемы, связанные с отсутствием
квалифицированной рабочей силы.
Высокие риски могут быть также обусловлены разным подходом к
работе и разной трудовой моралью, связанные с иными установками в
регионе или стране с другой культурой.
Экономические риски
Проекты с традиционно высокими рисками (например,
проекты внедрения электронного документооборота или проекты
реконструкции) при твердо установленной стоимости могут быть
связаны с большими опасностями не только для исполнителя, но и
для заказчика.
Исполнитель будет всегда стремиться выполнить проект
без убытков, даже за счет снижения качества работ. Поэтому в
таких случаях рекомендуется браться за проекты с твердой
стоимостью (также как и поручать их) только после основательного
анализа рисков и четкого согласования условий.
Другая разумная альтернатива заключается в том, чтобы
твердую стоимость устанавливать только для частей проекта с
обозримыми рисками, а остальную часть принимать по
фактическим затратам, что позволяет уменьшить финансовую
неопределенность проекта
Политические риски
Политические риски могут быть связаны с:
  запретом или ограничениями при перевозке различных
грузов;
  требованиями по участию в выполнении работ местных
предприятий;
 
дополнительными
налогами
или
особыми
обязательствами;
  влиянием местных групп с различными интересами, а
также ограничениями на трансфер капитала;
  принуждением к использованию местного персонала;
  односторонним толкованием договора;
  осложнениями/разрушениями, связанными с
вооруженными конфликтами;
  национализацией собственности.
Социокультурные риски
В зарубежных проектах особое значение
приобретает разнообразие культурных
и социальных условий. Сюда относятся,
прежде всего, такие институциональные
факторы, как семья, клановость, религия
и др. Кроме того, следует учитывать
специфические
представления
о
ценностях, которые могут, например
выражаться в сопротивлении населения
новшествам, существовании черных
рынков, семейственности, ненависти к
иностранцам, особых традициях и т.д.
Types of risk
Generic risk headings
• Broad headings are:
– Strategic risk. It includes a range of variables such as the market,
corporate governance and stakeholders.
– Operational risk. It includes the process itself, the asset base, the
people within the project team and the legal controls within which the
organization operates.
– Financial risk. It includes market, credit, capital structure and reporting
risk.
– Knowledge risk. It includes IT hardware and software, information
management , knowledge management, and planning.
– Catastrophic risk. It includes risk that cannot be predicted effectively
and therefore cannot be quantified accurately.
• Within these broad headings for risk types, there are several specific
subdivisions that can occur.
Market risk (business risk or dynamic risk)
•
•
Market risk is measured by changes and variations in the general marketplace. It is unavoidable, since it relates to factors that are outside the control
of the decision maker and could result in positive or negative impacts.
Market risk therefore provides the organization with the potential for both
profit and loss on trading.
Obvious examples would include:
–
–
–
–
–
•
•
share floatation;
competitor activities;
investment in research and development;
release of new products;
general economic activity.
Market business risk (MBR) arises from the company trading with its assets.
It is a risk to the company as a whole, and it therefore distributed among the
shareholders, creditors, employees and all other stakeholders.
Market financial risk (MFR) arises from the gearing ratio, which is the
measure of the financing of the organization. MFR is the risk of the annual
dividend falling to zero, so that equity holders make no return on their
shareholdings.
Static risk (specific risk or insurable risk)
• Static risk considers losses only.
• It looks at the potential losses that could occur and seeks to
implement safeguards and protection in order to minimize the extent
of the loss.
• The obvious examples would include:
–
–
–
–
–
fire insurance;
third party and public liability insurance;
professional indemnity insurance;
personnel insurance;
other optional forms of insurance.
• The organization can reduce the effects of specific risks by insuring
against them (where relevant) and by diversifying. By expanding the
range of new areas within an organization, the organization spreads
the specific risk and makes the system more resilient against
market-risk shocks, such as a sudden change in statute or a change
in government fiscal policy.

Predictable and unpredictable risks
•
Predictable risks are “known unknown” risks, such as
changes in interest rates during times of fluctuation in the
economy. They can be predicted with some accuracy
although not with certainty.
• Unpredictable risks are the “unknown unknowns”. This
cannot be predicted with any accuracy. F.e., a dynamic
internal unpredictable risk could be a project status
change.
Выявление рисков
• Основные методы:
1. Определение риска на основе структурного плана проекта.
2. Анализ отказов.
3. Контрольные листы.
• Последовательность действий при определении
рисков на основе структурного плана проекта:
– выявление рабочих пакетов, связанных с большими
рисками,
– определение возможных трудностей и количественная
оценка рисков,
– выявление возможных причин трудностей, уменьшение или
исключение проблем с наибольшей степенью риска.
Выявление рисков
• Для определения рабочих пакетов, связанных с
наибольшими рисками все работы включаются в список, и
каждая из них исследуется с помощью следующих
вопросов:
– могут ли возникнуть трудности в содержательной области?
(содержательный риск);
– могут ли возникнуть трудности с соблюдением сроков?
(временной риск);
– имеется ли сильное ограничение по финансам? (финансовый
риск).
• Для каждого рабочего пакета записываются все
мыслимые трудности, указывается вероятность их
возникновения и определяются затраты, которые могут
понадобиться на их устранение.
• Этот подход к анализу рисков может быть применен для
всех типов проектов и может быть начат в любых их
фазах.
Выявление рисков
Выявление рисков на основе анализа отказов
базируется на том, что проблемы часто возникают, когда
появляются отклонения технологических параметров
(количества, давления, температур, времени обслуживания
клиентов и др.). Поэтому ставится цель зарегистрировать все
мыслимые отклонения от нормальной эксплуатации и их
проанализировать. Если речь идет об установке, то исходя из
схемы установки, по каждой из входящих в нее составных
частей, записываются все возможные отклонения процесса от
нормы, определяются их причины и последствия.
При методе контрольных листов используются
детальные контрольные списки (вопросники), составленные на
основе опыта (своего или чужого) выполнения прошлых
проектов.
Анализ риска проекта
• Анализ риска проекта должен включать:
– источники рисков;
– факторы рисков;
– оценку рисков.
Значимость риска зависит от:
- последствий его проявления,
- вероятности возникновения,
- эффективности мер противодействия.
Background to risk
The concept of risk
•
•
Risk in the context of project management is a measure of the probability
and consequence of not achieving specific project goal. It depends both on
the likelihood (probability) of an event occurring and the consequences
(impact) of that event should it occur.
Risk is a function of the probability of an event occurring and the
consequences of the event if it does happen:
Risk = f (event, uncertainty, consequences).
•
Risk is also a function of the level of hazard represented by an event and
the degree of the safeguard that is put in place to counter it:
Risk = ( event, hazard, safeguard).
Risk conditions and decision making
• Risk is intrinsically linked to decision making.
• There are generally three main conditions under witch decisions can
be made:
– conditions of certainty;
– conditions of risk;
– conditions of uncertainty.
• Conditions of certainty apply where the outcome is known.
• Conditions of risk apply where is a reasonable probability that an
event will occur and where some kind of assessment can be made.
These are the “known unknown” events. Most risk management and
decision making take place under conditions of risk.
• Conditions of uncertainty apply where is not possible to identify any
known events. It is not possible to predict outcomes with any
accuracy.
Decision making under conditions of certainty
• Decision maker knows with 100% accuracy what the outcome will
be.
• Conditions of certainty can be represented using a pay-off matrix,
where profit for each strategy and state of nature are shown.
Strategy

N1 = up
N2 = even
N3 = down
S1 = A

S2 = B

S3 = C

$160 000 000
- $100 000 000
Decision making under conditions of risk
•
In most practical situations, there is no single dominant strategy for all
eventualities. In general terms:
Higher profits = higher potential risks
Higher profits = higher potential losses.
Strategy
Possible stage of nature
N1 = up
N2 = even
N3 = down
Probability = 25%
Probability = 25%
Probability = 50%
S1 = A
$100 000 000
$80 000 000
$60 000 000
S2 = B
$150 000 000

$80 000 000
S3 = C
$200 000 000
$160 000 000
- $100 000 000
The expected payoff for each strategy now is the sum of the payoffs for
each state of nature multiplied by the probability of that state occurring:
S1 = (100m x 0,25) + (80m x 0,25) + (60m x 0,5) = $75m
S2 = $102,5m;
S3 = $40m.
Decision making under conditions of uncertainty
Uncertainty criteria
• Under conditions of uncertainty, it is not
possible to predict what state of nature
will apply. One of several uncertainty
criteria may then apply
– Hurwicz criterion (maximax criterion).
– Wald criterion (maximin criterion).
– Savage criterion (minimax criterion).
– Laplace criterion.
Rules for decision making under conditions of
certainty, risk and uncertainty
•
Any of the four uncertainty strategies can be adopted, depending on:
–
–
–
•
how much money we can afford to lose;
the level of risk that we are willing to take;
what level of risk outcome that we can absorb.
In terms of general risk taking:
–
–
–
–
–
–
–
–
–
–
–
–
–
–
–
Don’t risk a lot for a little unless it is really worth it;
Always analyze risks very carefully;
Make sure that all risks have been identified;
Make sure that all possible implications have been identified;
Consider risk in terms of exposure and sensitivity;
Plan for risk in as much details as possible;
Always include an contingency plan;
Don’t accept risks for reasons of principle;
Don’t accept risks to avoid losing face;
Never risk more than you can afford to lose (unless you have to);
Consider odds and intuition;
Allow for the effects of bias;
Allow for the effects of groupthink;
Consider controllable and uncontrollable aspects separately;
Eradicate unknown factors as far as possible.
Rules for decision making under conditions of
certainty, risk and uncertainty
•
In terms of hazard and safeguard:
–
–
–
–
–
–
•
Maintain a low center of gravity;
Reduce the risk profile where possible;
Try to take risks in non-critical areas;
Consider defenses in relation to potential hits;
Maintain safeguards within reasonable limits;
If in doubt, ask the boss.
In terms of group development:
–
–
–
–
–
Allow for groupthink;
Beware unfounded delusions;
Remember that groups make more risky decisions than individuals;
Don’t confuse risk taking with boldness;
It is something prudent to be wary.
Rules for decision making under conditions of
certainty, risk and uncertainty
•
In more philosophical terms:
–
–
–
–
–
You can’t to avoid risk so accept it;
Be prepared to take risks or you won’t to be able to exploit opportunities;
Engineer risk to keep it within acceptable limits;
Use vision and think in expansive terms. Don’t allow risk to put you off;
Try new things because if you don’t you may become entrenched in the known
and become fearful of the unknown;
– Use risk to make money.
Источники рисков
- по персоналу:
- по руководителю проекта,
- по работникам проекта,
- по работникам предприятия, которых
затрагивают проектные решения,
- по советам предприятия,
- по лицам ответственным за безопасность,
защиту информации, охрану окружающей
среды.
Факторы риска
- пожелания о внесении изменений в проект,
- несоблюдение бюджета проекта,
- проблемы
с внешними ресурсами,
- появление новой техники,
- стремление к совершенству,
- проблемы с персоналом,
- ошибки планирования,
- ошибки по ходу выполнения проекта,
- технические проблемы,
- влияние окружающей среды,
- соблюдение сроков выполнения проекта и его
этапов,
- пригодность результатов,
- дополнительные требования.
Оценка рисков
Значимость риска зависит от последствий его проявления,
вероятности его возникновения и эффективности мер
противодействия этому риску. Часто эти три характеристики
не удается выразить в цифрах. В этих случаях их ранжируют.
Для наиболее вероятных и опасных рисков следует продумать
контрмероприятия и учесть их при планировании проекта.
Поскольку по ходу проекта возникают новые риски,
да и ранее выявленные могут оцениваться по новому, то в
течение проекта необходимо периодически возвращаться к
анализу рисков и производить их переоценку.

Оценка политического риска
При зарубежных проектах руководству проекта следует обязательно
разобраться с политическими рисками в соответствующей стране и
попытаться оценить их возможное развитие в период выполнения
проекта. Подходящим методом для этого является техника анализа
ценности.
Для оценки политического риска в какой-либо стране может быть
использован индекс BERI (Business-Environment-Index), который
трижды в год составляется 100 экспертами методом Дельфи на основе
следующих критериев:
· политическая стабильность,
·
установки по отношению к иностранным инвестициям и
прибыли,
· степень государственного участия в экономике,
· уровень инфляции,
· платежный баланс,
· бюрократизм,
Оценка политического риска
·
·
·
•
экономический рост,
соблюдение договоров,
уровень зарплаты и производительность труда,
конвертируемость валюты,
· наличие экспертов и сферы услуг,
· связь и транспорт,
·
местный менеджмент и партнеры,
· возможность получения краткосрочных кредитов, долгосрочных
кредитов, наличие собственного капитала.
Суммарный индекс может меняться в пределах от нуля до ста. Если в
результате оценки получается менее 40 пунктов, то сотрудничество с
этой страной, даже при весьма привлекательных проектах,
рекомендовано быть не может.

Уменьшение рисков
Часть рисков может быть распределена на
другие организации.
Фиксация распределения рисков
осуществляется в договорах с членами
консорциума, договорах с поставщиками,
страховщиками, банками и другими
носителями рисков.
По рискам, остающимся у подрядчика,
должны быть приняты соответствующие
технические и предпринимательские меры
противодействия.
Результаты анализа рисков представляются руководству
предприятия для принятия решения о том, браться за проект или
нет.
Risk handling
Approaches to handling risk
• The bunker approach.
– Decision makers try to allow for every possible risk and price
accordingly. They assume the the worst-case scenario and try to
recover every possible result.
– The obvious end result is a very expensive initial estimate for the
project.
– This approach is often used for high-quality projects or those where the
consequences of failure are large.
– Overprovision can itself constitute a risk. In trying to analyze and allow
every possible scenario, the product itself may become so expensive
that it is no longer viable.

Approaches to handling risk
• The ostrich approach.
– It assumes that everything will be all right. (AGAP – All Goes
According Plan)
– Sometimes the people get away with it; at other times the result is a
catastrophe.
• The ”gut reaction” approach.
– Some experienced decision makers use their intuition.
– Gut reaction uses a combination of knowledge, experience,
extrapolation and subjective assessment.
– This approach is itself risky. It is not normally recommended and
tends to be used where there is no other form of assessment.
• The aggressive approach.
– It assumes that uncontrollable risks can be brought under control by
pure aggression and determination.
Risk handling
Risk assessment and control
•

There are two essential components in any project risk management
strategy. There are project risk assessment and project risk control.
A risk management strategy should be developed in detail for a project
before the project actually starts, the strategy being implemented as early
as possible in the life cycle of the project.
Project risk assessment is the process of evaluating and describing the risk
in some way that allows objective or subjective evaluation and appraisal.
Project risk control is the operational process for measuring actual and
planned risk and monitoring the variance between the two as the basis for
corrective action.
Risk handling
Risk assessment and control
• There are three components of risk control. There are risk analysis,
risk handling, and risk feedback.
• Risk analysis involves the determination of the probability of
individual risky events occurring, and also of establishing some
measure of the potential consequences of each event occurring.
• Risk handling is the process of dealing with risks in order to reduce
the likelihood of individual events occurring.
• Risk feedback is the process where the results of occurred risks are
analyzed and any results and items for use in future strategies are
fed back into the system.

Risk analysis – risk map
•
•
The process of risk mapping is sometimes referred to as risk profiling or
even risk footprinting. It is basically a process of showing the relationship
between risk probability and impact for a range of given risks as a function
of time.
A basic risk map has four quadrants, although it may be expanded to more
sectors:
–
–
–
–
•

1: Red zone (high impact and high probability).
2: Upper yellow zone (high impact and low probability).
3: Lower yellow zone (low impact and high probability.
4: Green zone (low probability and low impact).
The risk map is dynamic. It shows the migration of certain risks over a
period of time.

The concept of risk management
Risk analysis – risk response
• Risk response basically centers on risk distribution.
• The distribution of risk will depend on a number of n0ncontractual considerations:
–
–
–
–
Is the outcome of the project worth the risk?
Who has the greatest risk control?
Who has the greatest risk liability?
What incentive does each party have?
• Most forms of contract require a more or less collaborative
approach to the equitable sharing of risk.
• Risk response include:
–
–
–
–
risk retention;
risk reduction;
risk transfer;
risk avoidance.

Ignoring the risk is obviously itself a high-risk strategy. Informed risk retention is
another consideration. This is most suited to risks that are characterized by small and
repetitive losses.
Risk may be reduced by a number of means. It may be possible to engineer risk out
of the equation. In edition, risk may be reduced by training and development, or by
redefining the aims and objectives of the project.
Risk transfer involves transferring the risk to others. Risk transfer through insurance
transfers the risk to the insurance company in return for a premium. Risk can also be
transferred through damages clauses within contracts (or through negotiations).
Not all risks can be transferred, and there may be some risks where it is not
economical to do so.
Risk avoidance means removing the risk in all forms from the project.
Risk may sometimes be avoided or reduced by seeking additional decision-relevant
information.

Risk analysis – risk control, policy and reporting
•
•
•
•
•
Risk control is the process of using the information that has been learned on
a project to assist in the later development of the project.
The risk identification and analysis systems may be incorrect or items may
have missed. It is very important that all assumptions and evaluation
processes are recorded and then measured in some way in order to see
whether or not they are working correctly.
In addition, the probability and impact of identified risks may change over
time. It is important that identified risks are constantly monitored and
reviewed.
Experience with risk and risk management is often documented into a risk
handbook.
There must be regular reporting on red-quadrant risks.
The concept of risk management
Risk analysis – risk control, policy and reporting
• Risk report should be produced to a timetable and be controlled by
an overall strategy.
• The level and frequency of reporting will depend on the significance
of the risk:
– The CEO would usually receive frequent progress reports, including
identified risk drivers and detailed risk maps.
– The Board would receive copies of these, and also intermediate sixmonthly reports.
– For periods less than six months, progress would be summarized by
executive managers and circulated within the various project teams.
– The CEO and senior managers receive informal communication on
progress on all levels.
The concept of risk management
Risk analysis – risk control, policy and reporting
• Risk policy is a statement of the policy of the organization in
terms of risk and risk management.
• Over and above the identification of risk holders and risk
strategies for “red quadrant” risks the risk policy establishes a
number of elements:
–
–
–
–
–
Overall aims and objectives.
Accountability for individual managers.
Formalized reporting channels.
Risk tolerances.
Authorization.
• Any risk policy should initially develop individual targets for
individual sections within the organization. Once this has been
completed, the policy is developed and worked up as a strategic
document.
