The critical path method (CPM) is a project management technique that helps construction managers ensure that their projects are completed on time and within budget. It is the most popular method for scheduling construction projects. CPM involves analyzing the various tasks involved in a construction project, determining their dependencies, and establishing the timeline for each activity. By identifying the critical path—the sequence of tasks that must be completed on time to avoid delays—project managers can focus on making sure those tasks are completed as scheduled.
