A. No need to worry project performance is good
B. While SPI is improving your CPI is below 1. You need to focus on improving CPI
C. While CPI is improving your SPI is deteriorating, You need to focus on improving SPI
D . While SPI is improving your CPI is deteriorating but is still > 1. You need to focus that CPI remains healthy while your SPI improves >1.
Please explain, how to resolve this.

CPI at 2 months wud be 4/2 =2
and CPI at 4 months wud be 10/8= 1.25
So CPI>1,but deteriorating.
SPI is increasing as seen from graph.
Hence option D is the correct one.
CPI at the end of 4 month
SPI = EV/PV
EV(4) = SPI X PV =.9 x 10 = 9M so CPI(4) = EV/AC =9/8 =1.125
CPI at the end of 2 month
EV(2) = SPI x PV =.5 x 10 =5 M ; So CPI(2) = EV/AC = 5/2 =2.5
From the example above CPI is detoriating but still > 1 but SPI =.9<1 PM has to improve SPI in the meantime have a watch on CPI.
Hence Option D is the right choice!
