The following table shows a WBS with 11 tasks. Note that each task has an ID, a description, duration, and a reference to predecessor tasks, if any, which must be completed before the task can begin. Construct a PERT/CPM chart from these tasks (similar to chart in Slide 20 Ch 3). Also, identify the critical path for this project (what are the tasks on the critical path and how long would it take?).
