Use the Program Evaluation and Review Technique to represent the project in an activity network. In conjunction with the Critical Path Method, use the activity network to find the shortest time possible to complete the project, to identify the critical jobs in the project, and to determine the earliest and latest that each activity can start and finish without making the project completion longer.a=1, b=1, c=6, d=5, e=2, f=5; andab=1x1=1, bc=1x6=6, cd=6x5=30, de=5x2=10, ef=2x5=10, af=1x5=5.
1. A project was planned using PERT with three-time estimates. The expected completion time of the project was determined to be 40 weeks. The variance of the critical path is 9. (e) The project manager wishes to set the due date for the completion of the project so that there is a 90% chance of finishing on schedule. Thus, there would only be a 10% chance the project would take longer than this due date. What should this due date be?
The following eight activities constitute an overall bar chart portrayal of a 4-month project. Two months after the start of the project. Activities A, C, D are completed, E is 50% complete and B is 25% complete. The total cost that has been spent is $10,500. For this project, using earned value concepts, determine the schedule and cost variance. Is the project ahead or behind schedule? Over or under budget? Activity A B VAHE с D F Cost $2,000 $8,000 $2,000 $5,000 $1,000 $15,000 Month 1 Month 2 Month 3 Month 4
We reduce Activity B to 4 weeks on each of the six houses.What affect will that have on the project completion time? Show work on the template provided. The x axis is the number of houses The y axis is time (number of weeks)
A project’s budget was originally $100,000. The CPI is 1.2, and the project is already 40% along. Assuming the project variances are typical, how much more money will you need to complete the project? $50,000 $43,000 $150,000 $83,000

Given the following activity network: Three nodes - A1, A2, A3; two paths - A1, A2 and A1, A3. Activity A1 takes 5 weeks, A2 takes 7 weeks, and A3 takes 4 weeks with a 50% probability and 10 weeks with a 50% probability. What is the project completion time under the worst-case scenario, that is, A3 is late and takes 10 weeks? A. 15 B. 10 C. 12 D. 9
Normal completion time and accelerated completion time Steps that can be taken to crash the project to the shortest time at the lowest cost. Hint: Determine each step's cost and the duration of the project at that stage.
A small software development project at Krishna Dhir's firm has five major activities.

There are four critical paths in a network. A-B-C-D-E, A-F-G-E, A-H-J-K-L-E and A-S-T-E. Each activity in this network can be crashed by 100 hours. The maximum possible reduction in the project duration will be: a. Insufficient information b. 1300 hours c. 500 hours d. 400 hours e. 600 hour
