The Critical Path Method (CPM) is a project management technique used to determine the longest sequence of tasks that must be completed on time for a project to finish by its deadline. By identifying these critical tasks, project managers can prioritize their efforts and allocate resources effectively. This helps in minimizing delays and ensuring that the project stays on track. In CPM, each task is represented as a node in a network diagram, and the relationships between tasks are shown as arrows. The critical path is the longest path through this network, and any delay in these tasks will directly impact the overall project timeline. Understanding the critical path allows teams to focus on what truly matters for project success.
