Project Management: Foundations to Practice · Cost Management and Earned Value Management
Earned Value Management Fundamentals
EVM is arguably the single most powerful, and most misunderstood, measurement system in project management. This chapter starts with the foundational distinction that most misunderstandings trace back to.
Earned Value Management, or EVM, integrates scope, schedule, and cost data into a single measurement system for objectively assessing project performance [18]. Rather than tracking these three dimensions separately, where a schedule status report and a budget status report could each look fine in isolation while masking a real underlying problem, EVM forces them into a single, mutually consistent framework.
Key Takeaways
- EVM integrates scope, schedule, and cost into a single consistent measurement system, rather than tracking them separately.
- The three core values are Planned Value (scheduled work's budgeted cost), Earned Value (completed work's budgeted cost), and Actual Cost (real spend).
- Actual Cost alone does not measure progress; spending 50% of a budget says nothing about how much scheduled work is actually done.
- Earned Value, not Actual Cost, is the reliable signal of genuine physical progress, making EVM a stronger early warning system than tracking spend alone.
