Earned value management (EVM) is a technique for measuring project progress and determining whether a project is on schedule and within budget. EVM uses earned value, which is the value of work completed to date, to calculate three key performance indicators: budget at completion, earned value, and cost variance. Budget at completion is the estimated total cost of the project, earned value is the actual value of work completed to date, and cost variance is the difference between earned value and budget at completion. These three indicators can be used to identify problems early and take corrective action before they become too costly or cause a project to miss its deadline.
