3. COST MANAGEMENT KNOWLEDGE
AREA OVERVIEW
All the processes needed to work
through a project within the confines of
the budget. The cost baseline is created
within this knowledge area’s processes.
5. PLAN COST MANAGEMENT PROCESS
The process of planning how
managing costs associated with the
project will be planned and
controlled
6. 7.1 PLAN COST
MANAGEMENT
Part of the Planning Process
Group
Establishes policies and
procedures for planning,
managing, and controlling
project costs
OUTPUT:
Cost Management Plan
7. COST MANAGEMENT PLAN
GUIDES THE ESTIMATION OF COSTS
AND BUDGET CONSTRUCTION
GUIDES THE PROPER USE OF
SPENDING WITHIN THE PROJECT
INCLUDED IN THE PROJECT
MANAGEMENT PLAN
8. LIFECYCLE COSTING
The cost of a product’s entire life
expectancy
Life expectancy value of resources
purchased for a project that can be
used in later projects or organizational
activities
9. VALUE ENGINEERING / ANALYSIS
Lower cost ways to do the same
amount of work
Can be brought on by process
improvements or better resource
purchasing conditions

11. ESTIMATE COST PROCESS
The development of estimates related
to the anticipated costs of project
activities
12. 7.2 ESTIMATE COSTS
Part of the Planning Process
Group
Each activity’s cost must be
estimated
Entire project cost is
estimated
Products purchased,
wages/labor, contingency
reserves for delay

16. COST TYPES
• Costs that can change with the amount of work output
produced
Variable
Cost
• Costs that do not change as the work output is
increased
Fixed
Costs
• Costs associated with producing project deliverables
Direct
Costs
• Overhead costs that can be accrued by multiple
projects (Program Costs, Organizational Operations)
Indirect
Costs
17. ESTIMATING COSTS
One-Point Estimation Each estimator submits a cost estimate for the activity
Parametric Estimation
Using historical records to collect average costs for activities
and using that as a basis to estimate current activities
Analogous Estimation
Similar activities are examined for their actual costs and used
to estimate for the current activity
Bottom-up Estimating
Estimations done for each activity or work package,
estimations are combined or rolled up to “Control Accounts” or
group of work packages. Total project costs are found by
combining “Control Accounts”
18. PERT ANALYSIS
Three cost estimates are provided for each activity
Optimistic Estimate (O) – Best case scenario for
activity completion times
Most Likely Estimate (M) - The most likely
completion time of the activity
Pessimistic Estimate (P) – Worst case scenario for
activity completion duration
Using the average of the estimates to estimate the
activity
Triangular Distribution
Beta Distribution
Used for time and cost estimates
19. ESTIMATION ACCURACY
Rough Order of
magnitude (ROM)
Range of estimates
between -25% and +
75% from actual costs
Budge Estimates
Fall in the Range of -
10% to + 25% from
actual costs
Definitive
Estimates
Range of estimates
between -10% to +10%
from actual costs
20. 7.3 DETERMINE BUDGET

21. THE DETERMINE BUDGET PROCESS
Aggregating costs of
activities or work
packages together to
create the project cost
baseline
22. 7.3 DETERMINE BUDGET
Part of the Planning
Process Group
Creates the cost baseline
Activity risks need to be
considered and cost
reserves need to be placed
into the estimates
23. COST RESERVES
Contingency Reserve
Reserve for handling known risks and is used
as part of the risk management strategy
Management
Cost reserved for unexpected risks or
changes
24. COST BASELINE
The base estimated costs
of the funds authorized for
spending on the project
Includes all estimated costs
and contingency reserves
but does not include
management reserves
26. 7.4 CONTROL COSTS
-PART OF THE MONITORING & CONTROLLING PROCESS
GROUP

27. THE CONTROL COSTS PROCESS
The monitoring of the project
expenditures throughout the project
and handling changes to the cost
baseline
28. 7.4 CONTROL COSTS
Part of the Monitoring &
Controlling Process Group
Calculating the actual costs spend
and measuring it against the cost
baseline
Work to prevent changes or
handle changes to the cost if they
do occur
30. EARNED VALUE MANAGEMENT
Can be used to measure the
performance of the project against the
baselines for scope, schedule, and
costs

31. EARNED VALUE MANAGEMENT
Planned Value
The planned or estimated value
for planned work
Earned Value (EV)
The value of the work
completed based on the
estimated value
Actual Cost (AC)
The actual cost for the
completed work
32. CALCULATING PV, EV, AC
PV = % Planned
Complete * Estimated
Total Budget
EV = % Actually
Complete * Estimated
Total Budget
AC = Actual Cost of
the Completed Work
33. VARIANCES
Schedule Variance (SV) Measures the performance of the schedule
Less than 0 indicates a project behind schedule
Greater than 0 indicates a project ahead of schedule
Cost Variance (CV) Measures the performance of the budget
Less than 0 indicates a project is over budget
Greater than 0 indicates a project that is under budget
Schedule Performance
Index (SPI)
Measure of the efficiency of the project schedule
Greater than 1 indicates a project is ahead of schedule
Less than 1 indicates a project is behind schedule
Cost Performance
Index (CPI)
Measure of the efficiency of the project costs
Greater than 1 indicates a project that is under budget
Less than 1 indicates a project that is over budget
34. CALCULATING VARIANCE
• SV = EV – PVSchedule Variance (SV)
• CV = EV – ACCost Variance (CV)
• SPI = EV/PVSchedule Performance Index (SPI)
• CPI = EV/ACCost Performance Index (CPI)
35. EARNED VALUE - FORECASTS
Total budget for all work items in the project to bring them to completion
Budget at
Completion (BAC)
Total estimated costs for completing all project work
Estimate at
Completion (EAC)
Estimate to complete the project from this point forward
Estimate to
Complete (ETC)
The forecasted completion costs of the project
If VAC < 0 Project will be completed over budget
If VAC > 0, Project will be completed under budget
Variance at
Completion (VAC)
Gives an indicator of what efficiency is needed to complete the project in order to make up for past negative
variances with the budget
If TCPI < 0 Project will more easily complete within budget
If TCPI > 0, Project will not be very easy to complete within budget
To Complete
Performance Index
(TCPI)
36. EARNED VALUE - FORECASTS
Estimate to Complete (ETC)
• ETC is equal to the estimates of the
remaining work items
• OR
• ETC = EAC - AC
Estimate at Completion (EAC)
• EAC = AC + ETC
• If all ETC work will remain within the
budgeted rate:
• EAC = AC + (BAC – EV)
• If the cost performance index is
expected to remain persistent:
• EAC = BAC/CPI
37. EARNED VALUE - FORECASTS
Variance at Completion (VAC)
• VAC = BAC – EAC
To Complete Performance Index
(TCPI)
• Original budget completion
requirement:
• TCPI = (BAC – EV) / (BAC – AC)
• Accommodating for past variances
• TCPI = (BAC – EV) / (EAC – AC)
