- The following represents a project that should be scheduled using CPM a. Complete the table b. Draw the Network Diagram c. What is the critical path? d. What is the expected project completion time?' e. What is the probability of completing this project within 16 days?In a network diagram, an activity:A) Is the largest unit of work effort consuming both time and resources that a project manager can schedule and control?B) Should always be something the company has had experience with. C) Is the smallest unit of work effort consuming both time and resources that a project manager can schedule and control?D) Must always have a single, precise estimate for the time duration.PERT NETWORK. A company is faced with the following PERT network situation (time in days): REQUIRED: Calculate (expected time) for each activity. For each activity, the estimates are , , , in that order. Calculate the total time for each path and identify the critical path.
- The client of a project has requested the project team to crash 8 hours of time. The table below provides the necessary information about the possible project crashing. (a) What is the crash cost for 8 hours of time-savings? (b) Assume the team calls the client and asks for a project extension, reducing the amount of time they need to crash. The project team has a $20 crash budget. Is the budget sufficient to crash 4 hours of time?

(a) Find the critical path. (b) Find the project completion time and the corresponding cost. (c) Suppose it is required to complete the project in 22 days. Find which activities to crash and by how much, to yield the minimum project cost. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.Activities A, B, C, and D are on the critical path of the network diagram below: The cost and duration of performing these activities is: Task A: $2,500 in 4 days Task B: $5,000 in 3 days Task C: $10,000 in 6 days Task D: $8,000 in 8 days At the end of day 10, tasks A and B are complete and task C is 25% complete. The amount spent thus far is $11,000. Given this information, how will you summarize the status of the project? Ahead of schedule, over budget Ahead of schedule, under budget Behind schedule, under budget Behind schedule, over budget
- You may need to use the appropriate technology to answer this question. Use the following network with activities and times estimated in days to answer the questions. A project network with 13 activities and 17 directed arcs is shown. Activity Start is connected to activity A, to activity B, and to activity C. Activity A is connected to activity D, to activity E, and to activity F. Activity B is connected to activity F. Activity C is connected to activity G and to activity H. Activity D is connected to activity K. Activity E is connected to activity I. Activity F is connected to activity I. Activity G is connected to activity I. Activity H is connected to activity J. Activity I is connected to activity K. Activity J is connected to activity K. Activity K is connected to activity Finish. Activity Finish has no arcs directed to other activities.
