Schedule variance (SV) is calculated by subtracting the planned value (PV) from the earned value (EV). Given the Schedule Performance Index (SPI) of 1.3, we can determine PV using the formula SPI = EV/PV. With an earned value (EV) of 12 weeks (actual time spent), we solve for PV: PV = EV/SPI = 12/1.3 ≈ 9.23. Therefore, SV is EV - PV = 12 - 9.23 ≈ 2.77. Rounding this value to the nearest whole number, the schedule variance is approximately 3.
ES = 16 AT=EV=12 SPI = EV/PV SV = EV-PV 1.3 = 12/PV PV = 9.23 (To confirm : SPI=EV/PV = 12/9.23 = 1.3 = same with the information given.) Thus SV = 12 - 9.23 SV = 2.769 SV ~ 3
SPI = EV/PV so EV =12 weeks. Based off our option PV being 2 would be 12/10 = 1.2 12/9 = 1.33333 so if PV is 15 weeks SV = EV-PV of 15-12 =3. Based off that i'd say answer is C for 3.
