Question

The primary objective of crashing in CPM is

• A. To decrease cost
• B. To increase cost
• C. To decrease project duration
• D. To optimise the path

Answer 1

Answer:

C. To decrease project duration

Project crashing is used to reduce project duration by investing more money. Only critical activities are considered and crashing is done on activities with lower cost slopes. The objective is to determine the optimum project duration with minimum cost. Steps include drawing a network diagram, selecting critical activity with minimum cost slope, reducing its duration, revising the diagram, and repeating until optimum duration is obtained.
