What is the schedule performance index (SPI) using the following data?
BAC=$ 100,000
PV=$50,000
AC=$80,000
EV=$40,000

A.
1.00

B.
0.40

C.
0.50

D.
0.80

Explanation:
Schedule performance Index (SPI) = EV/PV is an indicator whether the project is on time (SPI = 1) or behind the schedule(<1).

Cost performance Index (CPI) = EV/AC is an indicator whether the project is incurring expenses more than (CPA<1)/less than(CPI >1)/ equal to (CPI = 1)
