The critical path method (CPM) is a project management technique used to schedule tasks and identify the critical path of tasks that must be completed on time to meet deadlines. The critical path is the longest sequence of tasks in a project, where a delay in any critical path task will delay the entire project. CPM involves specifying tasks, determining dependencies, drawing a network diagram, estimating task times, and identifying the critical path to determine the shortest possible project duration. It helps project managers identify important tasks, reduce project timelines, and compare planned vs actual progress.

Introduction
The critical path method (CPM) is an
algorithm for scheduling a set of project
activities.
The critical path method, a project
management technique created in the
1950s, allows you to identify these
important tasks and stay on track
throughout your project.

 In any given project, you may have hundreds of tasks and
dozens of dependencies. It can feel almost impossible to
identify the most important tasks; the ones that, if missed,
will impact your whole project. In other words, the ones
you really need to worry about to make sure you meet
your deadlines.
 The critical path is defined as “the sequence of scheduled
activities that determines the duration of the project.” It
is the longest sequence of tasks in a project plan that
must be completed on time in order for the project to meet
its deadline. If there is a delay in any task on the critical
path, then your whole project will be delayed.

The critical path method is a step-by-step project
management technique to identify activities on
the 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.

 Planning the project so that it is completed
as quickly as possible
 Identifying activities where a delay in
their execution will effect the overall end.
