Earned Schedule

This article focus on Earned Schedule, which was introduced in 2003 a seminal article “Schedule is Different” by Walter Lipke, in The Measurable News, the quarterly magazine of the College of Performance Management, of the Project Management Institute. It is an extension to the theory and practice of earned value management (EVM). It has been stated that Earned Schedule provides a useful link between traditional Earned Value Analysis and traditional project schedule analysis — a link that some say has been missing in traditional EVM theory.
