(d) State critical path's in the network? (e) Assume that the project manager wants to shorten the project by five Weeks. What crashing decisions do you recommend to meet the desired completion time? When tie, must prefer least-cost option. To answer part =(8) MUST fill out the given table and MUST support your work separately.

(h) After reducing the project by five weeks, identify all the paths in the network and state their length? (Add as many rows as you needed) No. Paths Length of the Paths 1. 2. Can you further reduce the project duration? Yes/No. If 'No' Justify why? You are performing 15 crashing How many options alternative of activities available that can reduce the project duration by one week, list only the three highest cost options/alternative of activities.
