The Introduction and Effect of Critical Chain methodology in Earned Value Management(<Special Issue>Optimization for Project scheduling)

Abstract

In order to maintain project management properly with the EVM, we need to have a very accurate project plan. However, we have experienced huge difference between plans and results due to the addition of safety margins in baseline plans at our early stage of implementation of the EVM. In response to this, we have introduced the critical-chain method to the EVM to make baseline plans without safety margins. In this paper, we explain our introduction of the critical-chain method in the EVM and study its effectiveness.
