CRITICAL PATH SCHEDULING
CPM is an acronym for Critical Path Method. It usually refers to a computer-generated schedule that illustrates each activity start and end points, and includes predecessor and successor activities, activity durations and activity dependencies. Usually a single path of dependant activities defines the longest length of the total work on the project, all other activities being off the critical path. Activities defining work start, stop and durations along this longest path are those defined as critical, hence the term critical path.
