With regard to project management when of the following statements about prefect crashing is true?

Project crashing is a schedule compression technique used to shorten the project duration by adding resources to activities on the critical path. This method involves analyzing the trade-offs between cost and schedule to determine how to obtain the greatest schedule compression for the least incremental cost. For example, management might approve overtime, pay for expedited delivery of materials, or bring in additional personnel to complete specific tasks more quickly. The fundamental action in crashing is the allocation of more resources.

A. While crashing can increase risk and the potential for rework due to accelerated timelines and new resources, this is a consequence or a risk of the technique, not its definition.

B. This statement describes "fast-tracking," a different schedule compression technique where activities that would normally be performed in sequence are performed in parallel to shorten the overall duration.

C. This describes scope reduction or re-scoping. While reducing the project's scope can shorten the timeline, it is a separate strategy from crashing, which aims to complete the original scope faster.

Schedule Compression. The guide defines crashing as "A technique used to shorten the schedule duration for the least incremental cost by adding resources." It explicitly contrasts this with fast-tracking.

"Scheduling the Project

" discusses schedule compression techniques

defining crashing as the process of shortening activity times by adding resources

which invariably increases direct costs.

"Reducing Project Duration

" details the concept of crashing a project

stating

"Crashing a project is a term that has emerged for shortening the duration of an activity or a project beyond when it can be normally done... The usual methods for crashing a project are to add resources."
