2.3 Critical Path Method (CPM)
Tasks (possibly from a Gannt chart) can be put in a network diagram.
Earliest Start (ES) the earliest time a task can start.
Minimum Project Duration - the shortest time to complete the project based upon the longest path.
Desired Project Duration - the planned time for completing the project.
Latest Start (LS) - the latest a task can start for a Desired Project Duration.
Critical Path - the sequence of tasks that take the longest, and dictate the Minimum Project Duration.
