Explain the difference between baseline and forecast in EVM terms.

Explain the difference between baseline and forecast in EVM terms.

• A. Baseline is the approved plan; forecast predicts future performance using metrics like EAC and ETC.
• B. Baseline is a forecast; forecast is the approved plan.
• C. Baseline and forecast are interchangeable.
• D. Baseline is the cost to date; forecast is the schedule to date.

Answer: (A)

In earned value management, the baseline is the approved plan for scope, schedule, and budget that acts as the fixed reference against which performance is measured. It represents what you intend to achieve and is used to calculate variances and track progress; once approved, it stays in place and changes require formal change control. The forecast, on the other hand, is a forward-looking estimate of where the project is headed given current performance and remaining work. It uses metrics like Estimate At Completion (EAC) and Estimate To Complete (ETC) to project the final cost and completion date, updating as new actuals come in. So the essential distinction is that the baseline is the fixed, approved plan, while the forecast is the evolving projection of final outcomes derived from current performance data.
