Analyzing a project schedule using CPM

You are managing a construction project with the following tasks and dependencies:

Task A: $5$ days, no predecessor

Task B: $8$ days, must start after Task A$.$

Task C: $7$ days, must start after Task A$.$

Task D: $4$ days, must start after Task B$.$

Task E: $6$ days, must start after Task C and Task D$.$

Use the data above, draw the project network diagram. Identify the critical path using Critical Path Method by calculating the earliest start and finish times, and the latest start and finish times. Determine the total project duration.

Make a diagram showing the critical path and the project duration.
