What is Earned value management? What is the importance of it to measure the project performance?

Earned Value Management (EVM) technique used to track the Progress and Status of a Project & Forecast the likely future performance of the Project.

Earned Value Management (EVM) technique integrates the scope, schedule and cost.

If you are a project manager, then its important for you to learn EVM.

Earned Value Management is a Project Evaluation and Review Technique to Evaluate the Performance and Growth of PMO.

The implementation of  an ongoing  project within the Scheduled times saves the Escalation in value of any project, and review periodical evaluation, appropriate reporting and all will help the project to complete before time and PMO will get a chance to exhbit the professionalism. So far I didnt come accross with a practical experience in this connection with Big projects.  Any difference of opinion may please be discussed.  Thank you.
