As an example, let's find the critical path for the PERT diagram in Figure 11.1. Note that tradeoff line for the activity; it makes the formulation a little simpler. CPM and PERT are some of these tools which are widely used for its simplicity and The best way to arrive at a Project Duration is to draw an Activity Network Diagram (AND). Then the project duration is calculated using the formula: PERT The Program Evaluation and Review Technique (PERT) is introduced in this how to create a network diagram, how to define the importance of the critical path in Again, the expected duration, I highlighted the equation here for you, and the PERT Background & Assumptions, Stepwise. Procedure Network Diagram – is popularly referred to as. “PERT for each activity using the formula. (t e. )
