What Are Earned Value Management Techniques?
Understanding Earned Value Management (EVM) Techniques
Earned Value Management (EVM) is a powerful project management tool that integrates scope, time, and cost analysis to assess a project’s performance and progress. By using these points to measure progress, EVM helps project managers and decision-makers identify important variables in the plan early on, enabling them to make correct decisions to keep the project on track. This blog will explore key earned value management techniques and their applications in effective project management.
Breaking down EVM
At its core, EVM involves four primary data points:
- Planned Value (PV): The budgeted cost for the work scheduled to be completed by a certain date.
- Earned Value (EV): The budgeted cost for the work actually completed by said date.
- Actual Cost (AC): The actual cost incurred for the work completed by the particular date.
- Budget at Completion (BAC): The total budgeted cost of the project.
- By comparing these values, project managers can determine how well the project is following its budget and schedule to keep it on track.

Key Earned Value Management Techniques
Cost Variance (CV):
- Cost variance is a measure of budget performance and utilizes Earned Value and Actual Cost.
- Cost Variance Calculation: CV = EV – AC | (Cost Variance = Earned Value – Actual Cost)
- A positive CV indicates that the project is under budget, whereas a negative CV suggests that the project is over budget. This metric helps project managers understand the cost efficiency and take corrective action if necessary.
Schedule Variance (SV):
- Schedule variance measures the scheduled performance from the perspective of cost
- Schedule Variance Calculation: SV = EV – PV | (Schedule Variance = Earned Value – Planned Value)
- A positive SV shows that the project is ahead of schedule, while a negative SV means the project is behind schedule and needs correction.
Cost Performance Index (CPI):
- CPI measures the cost efficiency of the project.
- Cost Performance Index Calculation: CPI = EV/AC | (Cost Performance Index = Earned Value / Actual Cost)
- A CPI greater than 1 demonstrates that the project is performing accordingly with its budget, while a CPI less than 1 indicates poor cost performance.
Schedule Performance Index (SPI):
- The SPI measures the schedule’s efficiency and accuracy according to the budget.
- Schedule Performance Index Calculation: SPI = EV/PV | (Schedule Performance Index = Earned Value – Planned Value)
- If the SPI is greater than 1, the project is on or ahead of schedule, while a result less than 1 can mean it is falling behind schedule.
Estimate at Completion (EAC):
- EAC forecasts the total cost of the project at completion.
- Estimate at Completion Calculation: EAC = BAC/CPI | (Estimate at Completion = Budget at Completion / Cost Performance Index)
- By calculating the estimated final cost of a project, project managers can plan and control future expenses more effectively.
Estimate to Complete (ETC):
- ETC predicts the cost required to complete any remaining work.
- Estimate to Complete Calculation: ETC = EAC – AC | (Estimate to Complete = Estimate at Completion – Actual Cost)
- ETC helps overseers get a better idea of the future financial needs of the project.
To-Complete Performance Index (TCPI):
- TCPI calculates the efficiency needed to complete the project on budget.
- To-Complete Performance Index Calculation: TCPI = (BAC-EV)/(BAC-AC) | (TCPI = budget at completion – earned value / budget at completion – actual value)
- If the TCPI is greater than 1, then the remaining work must be performed more efficiently to stay on budget and schedule.
Benefits of Using Earned Value Management Techniques
Improved Visibility & Control: EVM provides a clearer picture of project performance and enables project managers to identify issues early, allowing for timely corrective actions and minimizing project risks.
Objective Performance Measurement: By integrating scope, time, and cost, EVM offers an objective measure of performance, maintaining an unbiased viewpoint by providing factual data for decision-making.
Enhanced Forecasting: EVM techniques like EAC and ETC provide accurate predictions for future project spending and efficiency, aiding in the effective allocation of resources and financial planning.
Informed Decision Making: The insights gained from EVM techniques provide project managers with the ability to make informed decisions based on the data and calculations, leading to better project outcomes and increased efficiency.
Overall, the seven techniques outlined in this article prove to be useful tools for leaders, project managers, and decision-makers. Earned value management is an indispensable tool for modern management. By providing a comprehensive and accurate view of project performance, project leaders can stay on top of the budget and schedule, ensuring successful project delivery.
