Over the course of a given project, often times, it is up to the project management team and or the project management team leader to make a determination that the previously determined and derived schedule may need to be modified and or tweaked in one way or another in order to accommodate one of more schedule events. This may be because a particular event is running behind schedule, or in other cases because a succeeding event’s timing has to e changed one way or another. One technique that is often employed by the project management team and or the project management team leader is that of project schedule compression. Schedule compression specifically speaking is a technique that is employed that involves taking the previously determined sch3edule and shortening the project schedule duration, but doing so in a manner which does not reduce and or minimize the project scope in any way. The term schedule compression can be compared and contrasted with the terms crashing and fast tracking.
This term is defined in the 3rd and the 4th edition of the PMBOK.
