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)
