Crashing analysis is done to evaluate the merits of reducing the overall completion time against the potential costs incurred for not completing the project at the desire time. It is used to identify which activities to crash that would result in overall lowest crashing cost. Let’s consider the following example.
Following is an example of project management with crashing. The four columns of data are the standard columns for this type of problem — the normal time and normal cost for each activity as well as the crash time and crash cost for each activity.
The project manager should crash the following activities (A,C,D,G and H) with the overall lowest crashing cost of 102. Each activities are crashed by one day. The project’s normal time of 16 days is reduced to 12 days.
