ID: 374075 • Letter: 1
Question
1. the SPI is= budgeted cost work performance/ budgeted cost work scheduled
= 100,000/60,000= 1.66, option C is correct.
2. EV= 500*100%+ 1000*50%+ 100*75%= 500+500+75= $1075
3. CPI= budgeted cost work performed/ actual cost of work performed
= 1075/1290= 0.833, option C is correct
4. CPI- the actual cost is higher than budgeted cost, hence it is unfavorable and behind the schedule
5.SPI- unfavorable and behind of the schedule. the work is not completed as per proportionate in the schedule and cost also increased than budgeted cost
6. total duration is 57 days
CPM is option A is correct
duration is increased by 2 days and critical path will be changed. last option is correct
time upto I= 21, total project duration 59
completion= 21/59= 36%

Suppose your PV for a project was $100,000 and your EV was $60,000. Your SPI for this project would be:
1.52
0.60
1.66
You cannot calculate SPI with the information provided
Activity A is worth $500, is complete and actually cost $500. Activity B is worth $1,000, is 50% complete and has actually cost $700 so far. Activity C is worth $100, is 75% complete, and has actually cost $90 so far. What is the total earned value for the project? (Hint: EV = PV x % Complete)
$1,600
$1,075
$1,290
-$1,075

Using the information in Question 2, calculate the CPI for the project.
1.20
1.05
0.83
0.60
Describe the status of this project for the resulting SPI (Question 1).
Favorable, ahead of schedule
Unfavorable, ahead of schedule
Unfavorable, behind schedule
Cannot be determined
Describe the status of this project for the resulting CPI (Question 3).
Favorable, cost less than budgeted
Unfavorable, cost over budget
Unfavorable, cost less than budgeted
Cannot be determined

A – (C through I) – L – M – O – Q
A – (C through I) – L – M – P – Q
A – (C through G) – L – M – O – P – Q – R
If Activity B, Review field sales reports, takes 7 days to complete instead of the 2 days estimated, what happens to the total Duration and why?
Total Duration does not change because slack not totally used up
Total Duration does not change because only used up slack that was available
Total Duration increases by 2 days, because used up 3 days of slack plus 2 additional days
Total Duration increases by 2 days, because of critical path change, slack not overused
Assume Activity B takes 7 days as stated in the previous question. Activities A through I are now 100% complete. What is the total project percent complete?
