A crash program is a plan of action entailing rapid, intensive resource allocation to solve a pressing problem.
These time limits may originate from predictable events like weather cycles or financial deadlines, or they may be arbitrarily established as lifesaving measures in situations involving famine, disease, or military vulnerabilities.
Schedule compression occurs when deadlines appropriate for expected conditions are shortened while the program is in progress.
[2] Fast-tracking involves working simultaneously on activities that would have been performed sequentially under normal circumstances.
[2] Project crashing occurs when additional resources are required to meet the established deadline.
