How Critical Path is Identified and What Information It Yields

By November 16, 2020No Comments

Critical path is identified with the use of Critical Path Method (CPM), which involves identifying:

  • Activity duration

  • Activity relationships (any relationship i.e. SS, FF, FS, SF)

  • Activities with zero Total Float (activities which can’t be delayed. If delayed, project end date will be effected)

This resultant critical path gives us the following:

  • Longest path (longest set of activities) in the project. In other words it gives us project duration
    Project end date.

  • Critical Path activities (activities that fall on Critical Path which also have zero Total Float)
    Early and Late dates of activities (detail in next slide)
