4.
Given the following project network, baseline, and status information, develop status
reports for periods 2, 4, 6, 8, and complete the performance indexes table. Calculate the EACf
and the VACf . Based on your data, what is your assessment of the current status of the project?
At completion?

Based on your data, what is your assessment of the current status of the project? At completion?
At the end of period 8, the project is 74.75% complete (EV/BAC) and $23,000 under budget. At
this point, the project should have amassed an actual cost of $154,000, when it actually cost
$131,000. This savings is a good sign as it indicates we are getting $1.18 worth of work for
every $1.00 we spend. Based on this current rate of operation, the project should come in
$31,000 under budget. The downside is that while there is a substantial savings, the project does
appear to be behind schedule.
6.
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?

RUNNING HEAD: CHAPTER 13 EXERCISES
What is your assessment of the project at the end of period 6? It is important to first note the
critical path 1, 4, 6, & 7. At the completion of the 6th period, activity 4 should be completed but
is only 80% complete. Since the actual cost of activity 1 resulted in a savings of $500, perhaps
this savings can be utilized to crash this activity to get the project back on schedule. If nothing is
done, the project will not complete on time.
