In this homework assignment, you will be working through two crashing problems and four earned value problems. All the information you need is included within this Homework packet. Make sure you answer all parts of the questions in their entirety.
Once you have worked through the problems, please post your responses to the Dropbox. Please refer to the course Syllabus for the due date.
PROBLEM 1
Use the network diagram below and the additional information provided to answer the corresponding questions. [15 points]
a) Give the crash cost per day per activity. [10 points]
A. 800 – 300 / 7 – 3 = 500/4= $125 B. 350 – 250 / 3 – 1 = 100/2= $50 C. 900 – 400 / 6 – 4 = 500/2= $250 D. 500 – 200 / 3 - 2 = 300/1= $300…show more content… [2 points]
39 / 34 = 1.14
b) Is the project cost efficient or not efficient? [2 points]
It is cost efficient
c) Calculate the schedule performance index (SPI). [2 points]
39 / 42 = 0.93
d) Is the schedule efficient or not efficient? [2 points]
It is more on the not efficient side since it is lower than 1.0, but it is close enough to 1.0 that it is not very inefficient.
PROBLEM 5 [8 points] Day | AC | PV | EV | 65 | $550 | $735 | $678 |
a) Calculate the cost variance (CV). [2 points]
678 – 550 = $128
b) Calculate the cost performance index (CPI). [2 points]
678 / 550 = 1.23
c) Calculate the schedule variance (SV). [2 points]
678 – 735 = -57
d) Calculate the schedule performance index (SPI). [2 points]
678 / 735 = 0.92
e) Given these data, what should a project manager do with respect to this project?
The project manager is under budget but behind schedule. He/She should spend some of their savings getting more resources to put them back on schedule.
PROBLEM 6 [8 points] Day | AC | PV | EV | 65 | $760 | $735 | $678 |
a) Calculate the cost variance (CV). [1 point]
678 – 760 = -$82
b) Calculate the cost performance index (CPI). [1 point]
678 / 760 = 0.89
c) Calculate the schedule variance (SV). [1 point]
678 – 735 = -57
d) Calculate the schedule performance index (SPI). [1 point]
678 / 735
