What does the critical path method (CPM) help determine in project scheduling?

The critical path method (CPM) is a project management tool that helps determine the longest stretch of dependent activities within a project schedule. By identifying the critical path, project managers can ascertain which sequence of activities must be completed on time for the overall project to be completed on schedule. Any delays in the activities on this path directly affect the project’s finish date, emphasizing their importance in the overall timeline.

This method involves constructing a project schedule by analyzing the relationships and dependencies between various tasks. By understanding the critical path, project managers can prioritize resources and efforts towards these essential activities, ensuring efficient time management and the successful completion of the project.

The other choices do not align with the primary function of the critical path method. Determining the total number of workers required relates more to resource allocation than scheduling, while the location of the project site and funding sources pertain to planning and budget considerations, respectively, rather than the sequencing and timing of project activities.
