TCPI – To Complete Performance Index

TCPI = (BAC – EV) / (BAC – AC)

先計EV:  CV = EV – AC.  -5 = EV – 80, EV = 75

TCPI = (130-75) / (130 – 80) = 55/50 = 1.1

So. Answer is B

Example 2:

Q: The project’s budget is US$750,000. At day 42, 40% of the project is completed, at a cost of US$500,000. After the project manager reports the CPI, the customer refuses to add more funds to the project. To complete the project on time and on budget, the project’s to-complete performance index must be which of the following?

A 0.6, B 0.9, C 1.4, D 1.8

A: If the customer refuses to add more funds, so the TCPI should use BAC rather than EAC. TCPI = (BAC – EV) / (BAC – AC)

EV = 750 x .4. i.e. 300

TCPI = (750-300) / (750 – 500)

= 450 / 250 = 1.8

So answer is D.

Example 2-2

Ques: In the same case, rather then client refused, they agree to give extra budget to original EAC. What is the TCPI?

Ans: As the EAC now is EAC = 750K / CPI, CPI = EV/AC, CPI =300/500 = 0.6 EAC = 750/.6 = 1250.

TCPI = (BAC-EV)/(EAC-AC),   TCPI = (750-300)/(1250-500) = 450/750. TCPI = 0.6

Example 2-3

In the same case, this time, the client said that they can increase the budge to only $1000K. what is the TCPI ?

Ans: So follow the same rate of burning cash, the EAC should be 1250. However the client only offer 1000.

So TCPI = (BAC-EV) / (1000-AC)

TCPI = (750-300)/(1000-500) = (450/500) = 0.9
