Earned Value Management (EVM) is a project performance management methodology that integrates cost, schedule, technical scope, and risk to assess progress against a baseline, use that information to identify problems, and forecast cost (and, to a certain extent, schedule) at completion.
Earned Value Analysis (EV Analysis, or EVA) is the act of using the EV metric, along with other project KPIs, to identify and quantify problems, assess risk, and forecast costs at completion. An experienced EV Analyst utilizes basic and advanced techniques to assess project performance and supply project managers with the information they need to make critical decisions.
