Cherry Jones owns a homeopathic medicine company called Faithhealers. She sells vitamins and other relatively nonperishable products for those who want choices regarding alternative medicine. Cherry is developing a new system that would require her staff to be retrained. Given the information in Figure 3.E X3, make a P E R T diagram for her and identify the critical path. If Cherry could find a way to save time on the “write use cases” phase, would it help? Why or why not?

What will be an ideal response?

It would not help if Cherry could find time to save on the write use cases activity (activity E). The time for activity E is four weeks and is precedent to activity G. Activity F is also precedent to activity G, and Activity D is precedent to Activity F. The total time for Activity D and activity F is five weeks, which is greater than activity E (four weeks).
