Critical Method Vs PERT Method
Apart from the Critical Path Method, there is another method called Project Evaluation and Review Technique (PERT) which you can use to schedule your project. The main difference between the two is CPM is mainly based on the deterministic approach to finding critical paths. On the other hand, PERT is a probabilistic method that defines the sequence of tasks using the probable time. It has three measures namely Most probable, optimistic, and pessimistic to find the duration of tasks. The following table highlights the key difference between the CPM and PERT method.

It addresses uncertainty through a weighted average formula. |

Identifies |
CPM identifies float as the time difference between early and late start times. |
It considers float but often focuses more on the critical path for project control. |

Suitable for |
It is well-suited for projects with well-defined activities and limited uncertainty. |
This method is preferred for projects with high uncertainty and complex, non-repetitive tasks. |

Approach type |
It is a simple approach. |
It is more complex with the statistical analysis and probability distributions. |

Project Managers often find it challenging to accurately determine the tasks and activities for executing the project plan. This is important not only for meeting the stakeholder expectations but also for managing the project quality from the end-users perspective. However, planning these activities can be done in more than one way. Or, we can say there are multiple paths for the project tasks.
But out of these, which path is Critical for our Project? In this article, we will learn about the Critical Path, one of the most important topics of Project Management. So, let us get started without any delay.
