2How Is Your Project Doing?
- Ahead of schedule?
- Within your approved Budget?
3How Is Your Project Doing?
- What is your cost estimate at completion?
- Will you be ahead or behind the scheduled
completion date?
4Agenda
- Explanation of Earned Value Management (EVM)
- The traditional Two Dimensional System of
Evaluation - EVM Three Dimensional System of Evaluation
- Critical Variables in EVM
- EVM Formulas
- Applying EVM on projects
- Example
5Earned Value Management
- Method for integrating scope, schedule, and
resources, for measuring project performance. - Compares what was planned with what was actually
spent with what was actually earned
6Earned Value Management
- Developed in the 1960s
- Popular method for reporting and controlling
project in the Department of Defense - A common language to report progress and cost
against a project - Helps answer the questions
- Are we on schedule?
- How much did the work we do cost?
- Are there variances?
- Based on these trends, how much will it cost by
the end of the project?
7Early Warning System
- based on the Project Performance Plan
- and Projects Actual Performance against
- the Plan,
- the project will likely take this much time to
finish, and - spend this much money.
8Traditional System(Two Dimensional)
- Cost compares what was planned to be expended
versus what was actually expended - Time Compares the date you are on a project
versus when the project is to be completed - Production Compares how much work was planned
to be completed versus how much was actually
completed.
9Earned Value(Three Dimensional)
- 1. Actual work that was earned
- versus
- 2. Work that was accomplished
- versus
- 3. Work that was scheduled to be accomplished
10Critical Variables to EV Performance Indices
- Quality of the project baseline plan
- Actual performance against baseline plan
- Managements determination to control (change)
the final results
11Project Baseline
- Basis of performance measurement
- Represents technical, cost and schedule
objectives of the project - Cashflows
- Outside Material
- Outside Services
12Scope of Work
- The scope of work of entire project must be
defined - The Work Breakdown Structure (WBS) identifies and
groups major deliverables - Integrate scope with budget and schedule.
13Performance Measurement Methods
- Fixed formula by task
- 0/100 , 25/75, 50/50
- Weighted Milestones Percent complete based on
specific work - (milestone) accomplished.
- Percent Complete
- Increment completed / total activity or task
- Equivalent Completed Units
14Cost Account Plan
15Project Description
- Installed approximately 14.5 miles of
transmission line of which about 4,000 feet was
installed underground. - Installed 93 steel poles 52 poles were direct
buried and 41 were mounted on pier foundations.

19Controlling Change
- Essential Change Management Control System in
the Project Plan prevents incorrect,
inappropriate, or unauthorized changes to the
project. - Inform appropriate stakeholders of authorized
changes to the Baseline (scope/quality, schedule,
cost)
20EVM Input Data Required
- PLANNING PHASE
- Planned Value (PV)
- Budget At Completion (BAC)
- Complete - Planned
- EXECUTING CONTROLLING PHASES
- Actual Cost (AC)
- Complete - Actual
21Calculations from Input Data
- Earned Value - EV
- Cost Variance - CV
- Schedule Variance - SV
22Calculations for Analysis
- Cost Performance Index - CPI
- Schedule Performance Index - SPI
- Budget at Completion - BAC
- Estimate to Completion - ETC
- Estimate at Completion - EAC
- To Complete Performance Index - TCPI
23Primary Data Elements
- PV (Planned Value)
- The value of the amount of work that was
- planned to be accomplished on a task (or a
- project) as of a certain date in the baseline
- plan.
- BAC (Budget at Completion)
- Total cost of a task (or project) according to
- the baseline plan.
24Primary Data Elements (contd)
- AC (Actual Cost)
- The actual amount of money spent
- on a task (or project) as of a certain date.
25Performance Analysis
- EV (Earned Value).
- The value of the amount of work actually
- completed on a task (or project) as of a
- certain date, according to the baseline
- plan.
- EV Actual Complete x BAC
26Performance Analysis (contd)
- CV (Cost Variance)
- The difference between the value of work
- that was actually completed (EV) on a task
- (or project) and the cost that was actually
- spend (AC) on the task (or project) as of a
- certain date.
- CV EV - AC
- ( spending less than planned)
27Performance Analysis (contd)
- SV (Schedule Variance)
- The difference between the value of work
- that was actually completed (EV) on a task
- (or project) and the work that should have
- been done (PV) as of a certain date.
- SV EV - PV
- ( Ahead of Schedule)
28Performance Analysis (contd)
- CPI (Cost Performance Index)
- The ratio of the value of work actually
- completed (EV) on a task (or project) and
- amount actually spent (AC) on a task (or
- project) as of a certain date.
- CPI EV/AC
- (gt1 Spending less than planned)
29Performance Analysis (contd)
- SPI (Schedule Performance Index)
- The ratio between the value of work that was
- actually completed (EV) on a task (or project)
- and the work that should have been done
- (PV) as of a certain date.
- SPI EV/PV
- (gt1 Ahead of Schedule)
30Performance Analysis (contd)
- ETC (Estimate To Completion)
- The forecasted cost of the remaining task
- (or project) is calculated by CPI or
- CPI x SPI
- ETC Remaining Work / CPI
- (BAC - EV/ CPI
- or
- ETC Remaining Work/ (CPI x SPI)
- (BAC - EV/(CPI x SPI)
31Performance Analysis (contd)
- EAC (Estimate at Completion)
- The value expressed in either dollars or hours
- to represent the projected final cost of work
- when completed. The EAC equals the actual
- costs (AC) incurred plus the estimated costs
- to complete the remaining work (ETC).
- EAC AC ETC
32Performance Analysis (contd)Ranges of Estimate
at Completion
- High-End Projection (Cumulative CPI x SPI)
- EAC AC (BAC - EV) / (CPI x SPI)
- In-Between Projection (80 CPI x 20 SPI)
- EAC AC (BAC - EV) / (0.8 CPI x 0.2 SPI)
- Low-End Projection (Cumulative CPI)
- EAC AC (BAC - EV) / CPI
33To Complete Performance Index
- TCPI Project performance which must be
- achieved on all remaining work in order to
- meet the financial goal by management
- TCPI Work Remaining / Funds Remaining
- (Total Budget - Earned value)
- (BAC - Actual Costs)
- (BAC - EV)
- (BAC - AC)

45Float and Management Reserves
- The project manager should control contingency
reserve and schedule float - The work at hand expands to fill the time
available - Expenditures will rise to meet the budget.
- The remaining management reserves should be
added to EAC until such time when the reserve is
no longer needed.
