1. Introduction to Earned Value Management (EVM)

Earned Value Management (EVM) is a project management technique that integrates scope, schedule, and cost to measure project performance and progress. Originally developed by the U.S. Department of Defense in the 1960s, EVM is now widely used in industries such as construction, IT, aerospace, and manufacturing.

Why is EVM Important?

Traditional project tracking methods (e.g., comparing planned vs. actual costs) fail to provide a holistic view of project health. EVM, however, answers critical questions:

• Is the project on schedule?
• Is it within budget?
• What is the expected final cost and completion date?

By combining planned value (PV), earned value (EV), and actual cost (AC), EVM provides early warning signs of project risks, helping managers take corrective actions.

2. Key Concepts and Terminology in EVM

A. Planned Value (PV) – “What Should Have Been Done?”

– Also called Budgeted Cost of Work Scheduled (BCWS).
– The estimated cost of work planned to be completed by a given date.

Example:
A software project has a total budget of $100,000over 10 months. After 5 months, the planned value (PV) should be $50,000 (50% of the work).

B. Earned Value (EV) – “What Was Actually Done?”

– Also called Budgeted Cost of Work Performed (BCWP).
– Measures the value of work completed at a specific time.

Example:
If only 40% of the software project is completed by month 5, the EV is $40,000(40% of $100,000).

C. Actual Cost (AC) – “What Was Spent?”

– Also called Actual Cost of Work Performed (ACWP).
– The real expenses incurred for the work done.

Example:
If the team spent $55,000 by month 5, the AC is $55,000.

D. Budget at Completion (BAC)

– The total planned budget for the project.

Example:
For the software project, BAC = $100,000.

4. Benefits of Using EVM in Projects

• Early Warning System – Detects delays/cost overruns before they escalate.
• Data-Driven Decisions – Helps managers adjust resources or timelines.
• Improved Accountability – Tracks team performance objectively.
• Better Forecasting – Predicts final costs and deadlines accurately.

5. Challenges and Limitations of EVM

• Complexity – Requires training to implement correctly.
• Data Accuracy – Relies on precise progress tracking.
• Not Suitable for Agile Projects – Works best for fixed-scope projects.

6. Examples of EVM Calculation

Scenario: Suppose you have an EPC project with the following characteristics:

• Total Budget (BAC): $10,000,000
• Project Duration: 12 months

At Month 6:

• Planned Progress (Scheduled Work): 50% (so 50% of budgeted work should be done)
• Actual Progress (Work Completed): 40%
• Actual Cost (AC): $4,500,000
