CPM - critical path method is an important piece in automation, FlowWrigt uses this algorithm in various parts of the application.

• Display when tasks are going to start and end
• Display what tasks are in the critical path, impact to these tasks have an effect on the overall plan
• To figure out if a plan is on time or late

Here's a more detail explanation of critical path method.

The critical path is a project management tool that helps identify the tasks that must be completed on time in order for a project to be completed on schedule. It is a way to visually represent the project timeline, with each task represented as a node on the path. The length of each task is represented by the distance between the nodes, and the dependencies between tasks are represented by arrows pointing from one task to another.

The critical path is determined by identifying the tasks that have no slack, or buffer time. These are the tasks that must be completed on schedule in order for the project to be completed on time. The critical path is the longest path through the project, and it determines the overall duration of the project. Any delay in completing a task on the critical path will result in a delay in the completion of the entire project.

One way to manage the critical path is to use the critical path method (CPM). This involves creating a network diagram that represents the tasks and dependencies in the project. The CPM allows project managers to identify the critical path and to monitor progress on the critical tasks. It also helps to identify potential bottlenecks and to develop contingency plans to address them.

Another tool that can be used in conjunction with the critical path is the critical chain method (CCM). This method focuses on managing the resources needed to complete the tasks on the critical path. It involves adding buffers, or reserve time, to each task on the critical path in order to account for uncertainties and risks. By adding buffers, project managers can protect the critical path from delays caused by unexpected events or changes in the project.

In conclusion, the critical path is an essential tool for project management. It helps to identify the tasks that are most critical to the success of the project and to monitor progress on those tasks. By using the critical path method and the critical chain method, project managers can effectively manage the timeline and resources of their projects and increase the likelihood of delivering on time and within budget.
