8. Define a fast-track operation . Briefly discuss its pros and cons.
9. Mention examples in which using fast-tracking is bad, good, or a “must” option.
10. From the following table, draw the precedence network, perform the CPM
calculations, and complete the table entries, assuming interruptible activities.
