Project Management Problems 1. A small pilot study involves the following tasks: Activity Predecessor Duration A – Prepare questionnaire - 5 days B – Collect data A 6 " C – Hire staff A 5 " D – Analyze data B 12 " E – Implement results C, D 4 " Find the critical path and the project duration. 2. Suppose the above project is augmented by an activity F (Purchase software). Task F has no predecessors, but is itself a predecessor to task B. The duration of task F is 7 days. Find the critical path and the project duration. 3. A project is comprised of 8 tasks. Task times are uncertain; consequently, 3 time estimates are provided for each task. Durations (days) .

Unformatted text preview: “ 4 “ \$200 Suppose the benefit arising from reducing the project duration is \$500/day. Which tasks should be crashed, and by how much? What is the total net benefit? 5. The budgeted costs for a project are as given below: Task Predecessor Duration Budgeted Costs A-2 weeks \$10,000 B-3 “ \$30,000 C A 1 “ \$3,000 D B 3 “ \$6,000 E B 2 “ \$20,000 F C, D 2 “ \$10,000 G E 1 “ \$8,000 Develop a weekly budget for the project. 6. The above project is monitored at the end of 4 weeks for cost control purposes. Assume task A is delayed by 1 week; also, it is now estimated that task C will require a total of 2 weeks. All other tasks are on schedule. Actual expenses to date are shown below. Task Actual Expense A \$12,000 B \$30,000 C \$1,000 D \$2,000 E \$11,000 F-G-Find the % complete for each task. Establish the budget variance for each task and for the entire project....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
