Critical path

This is simply regarded as the longest path via a network diagram, that shows the shortest amount of time by when project can or should be completed. the critical path method commonly called CPM is broken down into:

Earliest start time (ES) - This is simply the fastest or earliest a said activity can start without starting before any formal activities.

Earliest finish time (EF) - This is how fast or earliest an activity can finish.

Latest start time (LS) - This is simply known as the latest time an activity can start without delaying the entire project.

Latest finish time (LF) - This is simply the latest time an activity can finish without delaying the entire project.

Critical Path Analysis is a known project management tool that lets out all the individual activities that make up a larger project and it often shows the order in which activities have to be undertaken etc,
