Plan Cost Management establishes the policies, procedures, and documentation for planning, managing, expending, and controlling project costs. It provides guidance on how project costs will be managed throughout the project. Estimate Cost develops an approximation of the monetary resources needed to complete project activities using techniques like expert judgment, analogous estimating, and three-point estimating. Determine Budget aggregates the estimated costs of activities to establish an authorized cost baseline against which performance can be monitored. Control Costs monitors project costs and manages changes to the cost baseline using earned value management, forecasting, and performance reviews to recognize variances and take corrective action.

2. Project Cost Management includes the processes involved in Planning,
Estimating, Budgeting, Financing, Funding, Managing, and Controlling
costs so that projects can be completed within budget
1. Plan Cost Management (Planning Process Group)
The process that establishes the policies, procedures, and documentation for planning, managing, expending, and
controlling project costs.
2. Estimate Cost (Planning Process Group)
The process of developing an approximation of the monetary resources needed to complete project activities
3. Determine Budget (Planning Process Group)
The process of aggregating the estimated costs of individual activities or work packages to establish an authorized cost
baseline
4. Control Costs (Monitoring & Controlling Process Group)
The process of monitoring the status of the project to update the project costs & managing changes to the cost baseline.

3. Project Cost Management must consider stakeholder’s requirements for
managing costs – each stakeholder will measure costs differently.
Project Cost Management is primarily concerned with the cost of the
resources needed to complete project activities & the subsequent costs in
using and supporting the deliverables.
The cost management planning effort occurs early in the project & sets the
framework for each of the cost management processes so that
performance will be efficient.

9. 1. Expert Judgment
2. Analogous Estimating – compare with similar past projects when limited amount of detailed info
available
3. Parametric Estimating – uses statistical relationship relevant historical data & other variable
(like square footage) to calculate a cost estimate for project work. It provides higher level of accuracy
depending on past data
4. Bottom Up Estimating – cost of individual work packages are estimated to the greatest level for
detail. Its accuracy is influenced by the size & complexity of the individual activity or work package.
5. Three-Point Estimating
• Most Likely (cM) based on realistic effort assessment
• Optimistic (cO) based on best case scenario
• Pessimistic (cP) based on worst case scenario
Depending on the assumed distribution of value within the range, there are 2
formulas:
• Triangular Distribution. cE = (cO + cM + cP) /3
• Beta Distribution (from PERT analysis) cE = (cO + 4cM + cP) / 6

10. 6. Reserve Analysis
Contingency Reserves are the budget within cost baseline that is allocated for identified risks. It is often
viewed as part of the budget to address the “known-unknowns” that can affect a project. It may be a
percentage of the estimated cost, a fixed number, or may be developed by using quantitative analysis
methods.
7. Cost of Quality (COQ) – it cost less to prevent quality issue than to fix it
8. Project Management Software – Computerized spreadsheets, simulation, and statistical
tools are used to assist with cost estimating.
9. Vendor Bid Analysis – Cost estimates can be based on the responsive bids from qualified
vendors
10.Group Decision-Making Techniques
Team based approaches, such as brainstorming, the Delphi or Nominal Group Techniques are useful for
engaging team members to improve estimate accuracy & commitment to the estimates.

Quantitative assessment of the probable costs required to complete project work. It can be
presented in summary form or in detail. Cost are estimated for ALL resources that are applied
to the activity cost estimate
The amount and type of additional details supporting the cost estimates vary by application
area.
Supporting detail may include:
• Documentation of the basis of the estimate (how it was developed),
• Documentation of all assumptions made,
• Documentation of any known constraints,
• Indication of the range of possible estimates (like +/- 10%) to indicate that the item is
expected to cost between a range of values, and
• Indication of the confidence level of the final estimate.

• Control Costs is the process of monitoring the status of the project to update the project
costs and managing changes to the cost baseline.
• It’s key benefit is it provides means to recognize variance from the plan in order to take
corrective action & minimize risk.

18. Much of the effort of cost control involves analyzing the relationship between the consumption of
project funds to the physical work being accomplish for such expenditures that includes:
• Influencing the factors that created changes to the authorized cost baseline;
• Ensuring that all change requests are acted on a timely manner;
• Managing the actual changes when they occur;
• Ensuring that cost expenditures do not exceed the authorized funding by period, by WBS
component, by activity, and in total for the project;
• Monitoring cost performance to isolate and understand variances from the approved cost
baseline;
• Monitoring work performance against funds expended;
• Preventing unapproved changes from being included in the reported cost of resource usage;
• Informing appropriate stakeholders of all approved changes and associated costs; and
• Bringing expected cost overruns within acceptable limits.

20. 1. Earned Value Management (EVM)
A methodology that combines scope, schedule, and resource measurements to asses project performance & progress to
form performance baseline. It is a technique that requires the formation of an integrated baseline to measure performance
of the project.
EVM develops and monitor three key dimensions for each work package & control account:
• Planned Value (PV). Authorized budget assigned to scheduled work for an activity or WBS component (not
including management reserve). It is allocated by phase over the life of the project, but at a given moment, PV
defines the physical work that should have been accomplished. The total of the PV is sometimes referred to as the
Performance Measurement Baseline (PMB). Total PV for the project is also known at Budget At Completion (BAC)
• Earned Value (EV). A measure of work performed expressed in terms on the budget authorized for that work. EV
measured needs to be related to the PMB and it cannot be greater than the authorized PV budget for a component.
It’s often used to calculate the percent complete of a project.
• Actual Cost (AC). The realized cost incurred for work performed on an activity during a specific time period. It is
the total cost incurred in accomplishing the work that the EV measured. The AC needs to correspond in definition to
what was budgeted in the PV and measured in the EV. AC has no upper limit; whatever spent to achieve EV will be
measured.

21. Variances from the approved baseline will also be monitored:
• Schedule Variance (SV). – SV = EV – PV
A measure of schedule performance expressed as the difference between the Earned Value (EV) and the Planned
Value (PV)
EVM (Earned Value Methodology) is a useful metric that can indicate when a project is falling behind or is ahead of
its baseline schedule. The EVM schedule variance will ultimately equal zero when the project is completed because
ALL the Planned Value will have been Earned. It is best used in conjunction with Critical Path Methodology (CPM)
• Cost Variance (CV). – CV = EV – AC
The amount of budget deficit or surplus at a given point in time, expressed as the difference between Earned Value
(EV) and the Actual Cost (AC)
The cost variance at the end of the project will be the difference between the Budget At Completion (BAC) and the
Actual amount spent. The CV is very critical because it indicates the relationship of physical performance to the cost
spent. A Negative CV is often difficult for the project to recover.
• Schedule Performance Index (SPI) – SPI = EV/PV
A measure of efficiency expressed as the ratio on Earned Value to Planned Value. An SPI value of LESS than 1.0
means that it is behind schedule and GREATER than 1.0 means that it’s ahead of the schedule
• Cost Performance Index (CPI) – CPI = EV/AC
A measure of cost efficiency of budgeted resources, expressed as ratio between Earned Value to Actual Cost. A CPI
value of LESS than 1.0 means that it is Over Budget and GREATER than 1.0 means that it’s Under Budget

22. 2. Forecasting
As the project progresses, the PM may develop a forecast for the Estimate At Completion (EAC) that may differ from the
Budget At Completion (BAC) based on performance. If the BAC is deemed no longer viable, the forecasted EAC will be
used.
EACs are typically based on actual cost incurred, plus an Estimate to Complete (ETC) the remaining work.
The most common EAC forecasting approach is a manual bottom-up summation by the PM & the project team.
EAC = AC + Bottom-Up ETC
Three common methods of calculating EAC are:
• EAC forecast for ETC work performed at the budgeted rate: Accepts the actual project performance to date as
represented by the actual costs & predicts that ALL future ETC work will be accomplished at the budgeted rate.
When actual performance is unfavorable, the assumption that future performance will improve should be accepted
only when supported by risk analysis.
EAC = AC + (BAC – EV)
• EAC forecast for ETC work performed at the present CPI: Assumes what the project has experienced to date can be
expected to continue in the future.
EAC = BAC / CPI
