2. Outline
• Introduction
• Basic Elements of EVM
• Performance Analysis
and Forecasting
• Guidance for the use of
Key EVM Practices
3. Introduction
• Feedback of the Project
is critical
– Identify problems
– Early decision making
• EVM is one of the most
effective “performance
measurements and
feedback tools”
4. EVM
• “Management with
Lights On”
– Illumine where a project
is and where it is going
compared to where it
was supposed to be
• Patterns and Trends in
the past can be good
predictors of the future
5. EVM
• Part of Monitoring and
Controlling
– Scope
– Schedule &
– Cost
• Includes
– Measuring
– Analysing
– Forecasting
– Reporting
EVM
Scope
Time

Quality
& Risk
6. What’s the Project Status? Are we on Schedule?
Late by 2 Weeks
Mmm…so?...what’s the new finish date?
Couple of Changes…not
only schedule…cost…
7. EVMS Answers to
When is the project likely to be completed?
Are we currently under or over our budget?
How efficiently are we using our resources?
9. Planned Value
• Amount of resources (expressed in budget-
numbers) that are EXPECTED (PLANNED) to
accomplish a specific piece of work
– Budgeted Cost of Work Scheduled (BCWS)
– Spend Plan
– Cost Estimate Amount of resources ($) that are
expected to be consumed to
accomplish a specific piece of
work scope.
10. Example: Planned Value (PV)
Task Budget Jan Feb Mar Apr
1 12 6 6
2 20 8 12
3 28 7 21
PV 60 6 14 19 21
CUM 6 20 39 60
Total PV = 60
Total PV is called Budget at Completion (BAC)
11. Earned Value (EV)
• Amount of work accomplished at a given
point in time.
• Budgeted Cost of Work Performed (BCWP)
Snapshot of work
progress at a given point
in time
12. Example: Earned Value (EV) as of March
Task Budget Jan Feb Mar Apr
1 12 6 6
2 20 8 12
3 28 7 21
PV 60 6 14 19 21
CUM 6 20 39 60
EV 20 6 14 0
CUM 6 20 20
NO Work Performed (as per PLAN)
in March
For instance, in construction projects –
no physical work might happen as per
the plan, however money is spent on
certain equipments and tools (rented
crane, idle laborers for e.g.)
13. Actual Cost
• Amount of resources expended in a specific
time period to accomplish a task(s).
• Actual Cost of Work Performed (ACWP)
• Resource Expenditure against Planned Work
Amount of money spent
in a specific period of
time
14. Example: Actual Cost (AC) as of March
Task Budget Jan Feb Mar Apr
1 12 6 6
2 20 8 12
3 28 7 21
PV 60 6 14 19 21
CUM 6 20 39 60
EV 20 6 14 0
CUM 6 20 20
AC 25 6 14 5
6 20 25

Budget at Completion

16. Answering Project Management
Questions
Are we ahead or behind schedule? (VARIATION)
How efficiently are we using time? (PERFORMANCE INDEX)
When are we likely to finish work? (ESTIMATION/ FORECASTS)
Are we under or over our budget? (VARIATION)
What is the project likely to cost? (ESTIMATION/ FORECASTS)
What will the remaining work cost? (ESTIMATION/ FORECASTS)
How efficiently we must use our remaining resources ? (PERFORMANCE)
18. Variance
Variance
During the Project –
at a point in time
At Completion
• Variance
– Schedule Variance
– Cost Variance
• Both “during the course” of
the project and at the “end”
of the project
20. Variance
Are we ahead or behind schedule? – Schedule Variance (SV)
SV = EV – PV
Are we under or over budget? – Cost Variance ( CV)
CV = EV- AC
Will we be under or Over Budget (at the end)? –
Variance at Completion (VAC)
21. Project Management Question EVM Performance Measures Formula
Time-wise Schedule Analysis & Forecasting
Are we ahead or behind schedule? Schedule Variance SV= EV- PV
How efficiently are using time? Schedule Performance Index (SPI) SPI = EV/ PV
When are we likely to finish work? Time Estimate at Completion (EACt) EACt = BAC/ SPI
Cost-wise Cost Analysis & Forecasting
Are we under or over budget? Cost Variance (CV) CV = EV - AC
How efficiently are we using our
resources?
Cost Performance Index (CPI) CPI = EV/AC
How efficiently must we use our
remaining resources?
To-complete Performance Index (TCPI) TCPI = (BAC-EV)/ (BAC- AC)
What is the Project likely to cost? Estimate at Completion (EAC) EAC = BAC/CPI
Will we be under of over budget? Variance at Completion (VAC) VAC = BAC-EAC
What will the remaining work cost? Estimate to Complete (ETC) ETC = (BAC-EV)/ CPI
