Why is it important to determine the critical path of a project? What hap- pens if activities on this path are delayed? What happens if activities on this path are accelerated?
13. Calculate the ES, EF, LS, and LF times and the slack for each activity in the figure below, and identify the critical path for the project. Can the project be completed in 40 weeks? Assume that activity A actually fin- ished at 3 weeks, activity B actually finished at 12 weeks, and activity C actually finished at 13 weeks. Recalculate the expected project completion half of time. Which activities would you focus on in order to get the project this back on schedule? question 1 walk through Catracep 2nd Activity A 2 2 Activity B Activity D 4 3 Activity C 10 15 8 Activity E 5 7 Activity G 7 12 Activity F 6 20 Activity H 8 5

Using the following figure, perform resource leveling. Assume that each tak can be performed independently of the other tasks. Task 1 (2 workers) Task 2 (1 worker) Task 3 (3 workers) Day 1 2 Workers 6 6 LO 3 6 1 Task 4 (2 workers) 4 st st 4 Task 5 (1 worker) 5 6 2 3 7 3 Task 6 (3 workers) 8 4 9 10 3 3 لنا
12. Using the figure in question 11, perform resource-limited scheduling. Assume that you have only three workers available at any given time. What is the new completion date for the project?
12. a. Refer to the table below. What is the cumulative budgeted cost at the end of week 6? Task 1 Task 2 Task 3 Task 4 Total Cumulative TBC 1 2 3 30 10 15 5 70 10 40 30 170 10 25 4 Week 5 10 10 20 5 15 10 25 6 7 10 10 5 25 15 00 8 5 5 35 10 9 S 5 10 20 20 Amounts are in thousands of dollars. b. Below is a table of actual costs. What is the cumulative actual cost at the end of week 6? Determine whether there is a cost overrun or underrun. What is causing it?
Task 1 Task 2 Task 3 Task 4 Total 1 Task 1 Task 2 10 Task 3 10 2 1 16 30 10 Cumulative Amounts are in thousands of dollars. Week 3 2 8 26 18 10 10 3 80 100 4 12 c. Below is a table of the cumulative percentages of work completed by the end of week 6. What is the cumulative earned value of the project at the end of week 6? Is it good? Week 25 5 12 29 4 24 5 Task 4 Amounts are cumulative percent complete. 6 12 5 17 5 6 35 55 65 10 20 d. What is the CPI at the end of week 6? What is the CV? e. Calculate the FCAC using the first two methods described in the chapter. In addition, describe a third FCAC method you could use.
