Earned value management (EVM) is a powerful methodology that gives executives, project managers, and other stakeholders the ability to visualize project status throughout the project life cycle and consequently manage projects, programs, and portfolios more effectively. The earned schedule (ES) allows EVM metrics to be transformed to time or duration metrics to enhance the evaluation of project schedule performance and to forecast the duration needed to complete the project. When combined with schedule analysis, ES can enhance the project manager’s understanding of project schedule forecasts and provide further insights for making better decisions about project schedule and related parameters.
