Critical Pathway

NotesQuiz

The critical path through a network is:

the chain of activities whose times determine the overall duration of the project. 

Using our ‘Example Above’ (EA), the critical pathway will be ACFH.

A

Steps to finding the critical pathway:

  1. Find the final event where EET = LET (Event 7)

  2. Find the event series that leads up to this final event where EET = LET (in all of the events).

    (Event 1 - 2 - 4 - 6- 7)

  3. Find the activities that follow these events, this is the critical pathway. (A - C - F - H)

    The total of the durations of these activities will be the duration of the critical pathway.

    This is the critical pathway. It is the pathway where there is no float/slack.
