1. to complete performance index （TCPI） In order to achieve specific management objectives , Cost performance indicators that must be achieved for the use of remaining resources , Is the ratio of the cost of completing the remaining work to the remaining budget .

be based on BAC( Completion budget ) Of TCPI The formula ： TCPI=（BAC-EV）/ (BAC-AC).

2. If you accumulate CPI( Cost performance index ) Below benchmark , Then all remaining work of the project shall be immediately carried out according to TCPI (BAC) perform , To ensure that the actual total cost does not exceed the approved BAC( Completion budget ).  

be based on EAC( Completion estimate ) Of TCPI The formula ：TCPI=（BAC-EV）/(EAC-AC).
