Project Management – Chapter 8 Exercise Answer Key

4. Given the network plan that follows, compute the early, late, and slack times. What is the project duration? Using any approach you wish (e.g., trial and error), develop a loading chart for resources, electrical engineers (EE), and resource, mechanical engineers (ME). Assume only one of each resource exists. Given your resource schedule, compute the early, late, and slack times for your project. Which activities are now critical? What is the project duration now? Could something like this happen in real projects?

Instead of taking nine days the duration has been extended to 11 days and all activities are critical. Resource shortages are common in real projects and this problem demonstrates the impact resource constraints can have on project schedules.

5. Given the network plan that follows, compute the early, late, and slack times. What is the project duration? Using any approach you wish (e.g., trial and error), develop a loading chart for resources carpenters (C) and electricians (E). Assume only one carpenter is available and two electricians are available. Given your resource schedule, compute the early, late, and slack times for your project. Which activities are now critical? What is the project duration now?

Resource constraints extend the project duration from 12 days to 14 days and Activity 2 which was part of the original critical path is no longer critical path. All other activities are critical which illustrates the key point that resource constraints tend to increase the sensitivity of project networks.

9. You have prepared the following schedule for a project in which the key resource is a backhoe(s). This schedule is contingent on having three backhoes. You receive a call from your partner, Brooker, who desperately needs one of your backhoes. You tell Brooker you are willing to let him have the backhoe if you are still able to complete your project in 11 months.

Develop a resource schedule in the loading chart that follows to see if it is possible to complete the project in 11 months with only two backhoes. Be sure to record the order in which you schedule the activities using scheduling heuristics. Activities 5 and 6 require two backhoes, while activities 1, 2, 3, and 4 require one backhoe. No splitting of activities is possible. Can you say yes to Brooker’s request?

List the order in which you scheduled the activities of the project: First

3

Second

2

Third

1

Fourth

5

Fifth

4

Sixth

6

Which activities are now critical? 1, 2, 3, 4, 5, 6

Recompute your slack for each activity given your new schedule. What is the slack for: activity 1

0

activity 2

0

activity 5

0

You can say yes to the request. However, you have increased the risk of being late if a delay should occur.

11. Given the time-phased work packages, complete the baseline budget form for the project.

12. Given the time-phased work packages and network, complete the baseline budget form for the project.

14. Given the time-phased work packages and network, complete the baseline budget form for the project....
