Project Budgeting, Progress Monitoring, and Benefits Realization (LO5)
Crashing a Project
Identify the critical path.
Shorten activities on the critical path with the lowest crashing cost, one day at a time, as long as they haven't reached their shortest possible duration.
If two activities have the same crashing costs, crash the earlier one.
Cross-check that the critical path has not changed and identify new ones if they have.
Stop when the desired reduction in project duration is achieved.
Crashing Diagram
Depicts the accumulated costs of incremental project schedule reductions.
X-axis: Project duration in days.
Y-axis: Total project costs.
Managers can use it to discuss the optimal degree of crashing, balancing duration reduction with cost. Pay attention to the knee points of the curve.
