CH13 Exercises

1. In month 9 the following project information is available: actual cost is $2,000, earned value is $2,100, and planned cost is $2,400. Compute the SV and CV for the project.

CV= EV – AC = 2,100 – 2,000 = +100SV = EV – PV = 2,100 – 2,400 = -300

2. On day 51 a project has an earned value of $600, an actual cost of $650, and a planned cost of $560. Compute the SV, CV, and CPI for the project. What is your assessment of the project on day 51?

CV = EV – AC = 600 – 650 = -50SV = EV – PV = 600 – 560 = +40CPI = EV / AC = 600 / 650 = .92

3. Given the project network and baseline information below, complete the form to develop a status report for the project at the end of period 4 and the end of period 8. From the data you have collected and computed for periods 4 and 8, what information are you prepared to tell the customer about the status of the project at the end of period 8?

The project appears to be doing nicely. In both periods 4 and 8 the cost variance is positive—+$300 and +$400, respectively. This suggests a pattern of good cost variance that is under budget.

The schedule variance is also positive—+$300 and +$400 for period 4 and period 8. Since Task D is already 25% complete, Task B must have been completed at least one period early.

4. Given the following project network, baseline, and status information, develop status reports for periods 1-4 and complete the project summary graph (or a similar one). Report the final SV, CV, CPI and PCIB. Based on your data, what is your assessment of the current status of the project? At completion?

After 4 time periods the project is roughly 77% (PCIB) complete and is current getting only 83 cents worth of work for each dollar spent. The project is currently $10,000 over budget. There is $3,000 worth of work on critical Activity 5 that has not been completed as planned so the project is behind schedule. Since so much of the project has been completed the project is expected to come in over budget. The forecast cost at completion is $78,000 which is $13,000 over budget. Whether the project will be completed on schedule will depend upon whether Activity 5 can make up for lost time.

5. The following labor hours data have been collected for a nanotechnology project for periods 1 through 6. Compute the SV, CV, SPI, and CPI for each period. Plot the EV and the AC on the summary graph provided (or a similar one). Plot the SPI, CPI and PCIB on the index graph provided (or a similar one). What is your assessment of the project at the end of period 6?

After 6 time periods the project is roughly 66% complete and so far work on the project has taken 1,600 hours less work than planned. There is 400 hours worth of work on Activity 4 which was suppose to have been done that has not done. Since Activity 4 is on the critical path, the project is behind schedule. If schedule is the number priority, the project manager may want to consider investing some of the savings on accelerating critical activities.

After 12 time periods the project is roughly 60 percent and the project is only getting 70 cents worth of work for each dollar spent. The project is current $6,200 over budget. There is $1,000 worth of work that supposed to have been done that has not been completed according to plan. However, this work involved a noncritical activity and the project is on schedule with regards to the critical path.
