Abstract:  Elaborates the significance of buffering set and proposes a new computational method about that on the basis of foreign research results. This paper sets a progress control matrix, complexly considering the application and accomplishment condition of buffering, to monitor the use condition of buffering, so that it can provide a reference for the application of CCM in process management.

Key words:  Critical Chain Method (CCM); buffering set; impact factor; monitoring; progress control matrix
