Exercise 2: Schedule Compression TechniquesA project schedule has been developed using the Critical Path Method (CPM), and the project's critical path has a duration of 50 weeks. The project manager needs to reduce the project duration by 10 weeks. The following table shows the activities on the critical path and their associated crashing costs:\table[[Activity,Normal Duration (weeks),Crash Duration (weeks),Normal Cost (R),Crash Cost (R)],[A,8,6,15,000,25,000],[B,12,8,20,000,38,000],[C,10,7,18,000,30,000],[D,9,6,22,000,37,000],[E,11,9,25,000,33,000]]Tasks:Determine the critical path and the normal project cost.Apply the crashing technique to reduce the project duration by 10 weeks at the minimum cost. Show the activities crashed and the crashing cost for each step.Discuss the limitations of crashing and other schedule compression techniques (e.g., fast-tracking).Explain how resource constraints might affect the crashing decisions.
