PMI PMP Project Management

Answer: B - The definition of crashing means adding more resources to a project in an attempt to complete the project sooner.

Key Takeaway: Crashing typically helps your Schedule Performance Index (SPI), but will badly hurt your Cost Performance Index (CPI). The return is rarely cost effective, as it usually means bringing in new resources who have to get up to speed or paying people to work overtime.

Crashing is most effective when you have resources familiar with the project who can work more. For instance, if you have a part-time contractor who can go full-time for a few weeks, this can be an effective way to crash in a cost-effective manner. As such, keep resources with capacity can be an effective risk management technique.
