EV - Why & What
Why
Provides an “early warning” signs
for prompt corrective action
Provides an uniform unit of measure
(dollars or work-hours)
Requires different measures of
progress for different types of tasks
Need to consolidate progress of
many tasks into an overall project
status

What
Utilising Project Management
methods, practices, process & tools
Accurate definition of the defined
deliverable(s), timeframe & total
cost (direct & indirect) to deliver the
product
Detailed tasks / activities and work
not in the WBS is out-of-scope
Baseline of budget control a/c,
schedule, work measurement by
Control Account (hours, $, unit)

Time required for data measurement and

Quantifying / measuring work-in-progress
(WIP) can be challenging

Note…
Adhere to Project Management Best-Practices
Baseline your schedule
Analyse variance from your expectations
Diligently update your schedule and expenditure
Understand work products produced by the project
Organize your estimation and schedule around work
products
Do not re-baseline unless there is a formal,
approved change in scope

Cost Metrics
Cost Variance (CV)
Difference between a task’s
estimated cost and its actual cost
CV = EV – AC or BCWP –
ACWP
Negative Value = over budget
and / or behind schedule (vice
versa)
Deviations from the budget –
not a measure of work
scheduled vs. work completed
Cost Variance (CV)
Difference between a task’s
estimated cost and its actual cost
CV = EV – AC or BCWP –
ACWP
Negative Value = over budget
and / or behind schedule (vice
versa)
Deviations from the budget –
not a measure of work
scheduled vs. work completed
Cost Performance
Index (CPI)
Percentage of work completed per
dollar spent
CPI = EV ÷ AC or BCWP ÷
ACWP
Ratio > 1 = ahead of schedule
and / or under budget
(exceptional performance) –
vice versa
Cost Performance
Index (CPI)
Percentage of work completed per
dollar spent
CPI = EV ÷ AC or BCWP ÷
ACWP
Ratio > 1 = ahead of schedule

(exceptional performance) –

19. 19
Schedule Metrics
Schedule Variance
(SV)
Difference between the current
progress and originally
scheduled progress
SV = EV – PV or BCWP –
BCWS
A negative variance means the
project is behind schedule
Deviations from work planned –
not a measure of changes in
cost
Schedule Variance
(SV)
Difference between the current
progress and originally

SV = EV – PV or BCWP –
BCWS
A negative variance means the

Deviations from work planned –

cost
Schedule Performance
Index (SPI)
Ratio of the work performed to
the work scheduled
SPI = EV ÷ PL or BCWP ÷
BCWS
Ratio > 1 = ahead of schedule
and / or under budget (vice
versa)
Schedule Performance
Index (SPI)
Ratio of the work performed to

Earned Value Metrics
Minimum funds needed if things do not get
worse
Minimum funds = Original total budget ÷ CPI
Funds needed if things continue to get
worse at the same level of slippage
Funds needed = Original total budget ÷ (CPI x
SPI)

Variance - Do you know
What is the problem causing the variance?
What is the impact on other efforts, if any?
What corrective action is planned or under way?
What is the impact on time, cost & performance?
What are the expected results of the corrective
action?

Tasks = 20 Tasks (evenly divided over 4
months)
