Critical Path Method (CPM) is an algorithm for planning, managing and analyzing the timing of a project. Key Steps in Critical Path Method.

Learn how to calculate it with a step by step approach to calculating the critical path for a project. All numbers are shown and examples highlighted. The process of using critical path method in project planning phase has six steps. The step-by-step CPM system helps to identify critical and non-critical tasks from projects’ start to completion and prevents temporary risks. Managing Critical Path. It represents the longest path through the entirety of the project and typically this path consists of every single activity that must be concluded from the kickoff to the ultimate conclusion of the project.

Step 1: Activity specification. The critical path is the longest sequence of tasks in a project.

The tasks on the critical path control the duration of the entire project. You can use the Work Breakdown Structure (WBS) to identify the activities involved in the project. Now that we have calculated the critical path, we, the project managers, have to manage the critical path. Any increase in duration of a critical path task will always cause the project’s duration to increase.

The critical path refers to the sequence or order of schedule activities that will make up the entire duration of a project.

The critical path method is a core component of project management, and a must-know for any project management exam. When you string these dependent tasks together from start to finish you get your critical path. It is an approach to project scheduling that breaks the project into several work tasks, displays them in a flow chart, and then calculates the project duration based on estimated durations for each task. Critical Path Method (CPM) is defined as the way to predict work duration by using network analysis. Simply, Critical path method is generally used for the projects whose time duration is known with certainty and also the amount of resources required for the completion of the project is assumed to be known. Let's have a look at how critical path method is used in practice.

Critical Path Method Definition: The Critical Path Method or CPM is a network analysis technique concerned with planning and controlling of complex, but routine projects. The foundation of both critical path analysis and critical path method is the idea that you cannot start a task until a previous one has been finished. The critical path method is a step-by-step project management technique to identify activities on the critical path.
