In preparing for a team meeting you want to let the team know how they are doing on the project schedule overall. You calculate the task achievements as follows: Planning has a PV of $20,000 and an EV of $25,000, Testing has a PV of $17,000 and an EV of $15,000, and Design has a PV of $34,000 and an EV of $42,000. As a whole your project is:
|
a. 15% behind schedule |
|
b. 15% ahead of schedule, but over budget |
|
c. 15% behind schedule and budget |
|
d. 15% ahead of schedule |
please show the calculations ...answer is D

WOTS Inc has designed and installed landscaping around Hai’s new house. The estimated cost for the work was $50,000, based on a Cost Plus Fixed Fee contract (CPFF). If the fixed fee was set at 10%, the final cost was $47,000, and Hai’s initial payment was for $20,000, what is the amount of Hai’s final payment to WOTS Inc

Answer
1) I CANT SEEM to figure out the 1st one, post the solution described in the simulator
2) PV = 20000 + 17000 + 34000 = 71000
EV = 25000 + 15000 + 42000 = 82000
SV = 82000 - 71000 = 11000
SV % = (SV/PV) x 100 = (11000/71000) x 100 = 15%
So the answer is d) 15% ahead of schedule
3) I will just give a try for this one, not sure if the approach is right
Target Cost = 50000, Fixed Fee is 10% of estimated amount = 5000, I took the fee of he original amount because in CPFF, the fee is estimated at the begining as a percentage of the Target cost and will not change if the cost increases or decreases
Actual Cost = 47000.
Advance Payment = 20000
So Final Payment = 47000 + 5000 - 20000 = 32000.

I think you are right. for
I think you are right. for above 2 q.
1st question not tricky but with extra information.
4th month SPI = 0.88
Thus this rate will continue till completion.
88% work will be completed in 12 month
hence 100% will be completed in 12*100/88 = 13.6 months (A)
