Question

What and define CPM

Answer 1

The critical path method (CPM) is a step-by-step project management technique for process planning that defines critical and non-critical tasks with the goal of preventing time-frame problems and process bottlenecks. The CPM is ideally suited to projects consisting of numerous activities that interact in a complex manner.

In applying the CPM, there are several steps that can be summarized as follows:

• Define the required tasks and put them down in an ordered (sequenced) list.
• Create a flowchart or other diagram showing each task in relation to the others.
• Identify the critical and non-critical relationships (paths) among tasks.
• Determine the expected completion or execution time for each task.
• Locate or devise alternatives (backups) for the most critical paths.
