Understand Critical Path Method & Its Types

Critical Path Method

A project management tool called the critical path method (CPM) aids in estimating the shortest time necessary to accomplish a project. This is accomplished by reviewing every job that goes into a project and identifying the "critical path," or the task sequence with the longest length.

The critical path is the sequence of tasks that must be finished by the project deadline in order for it to be finished on schedule. Using the critical path technique, project managers may spot potential schedule bottlenecks and adjust the activities, their order, and their dependencies as necessary to maintain the project on schedule.

The CPM is a visual depiction of the project schedule that frequently takes the form of a network diagram and highlights the dependencies between jobs as well as the anticipated completion times for each one. Project managers can concentrate their efforts on making sure that the crucial tasks are finished on time and prevent delays that might affect the project's overall schedule by identifying the key path.

How Critical Path Is Determined

There are two ways to determine critical path:

  1. Forward Pass: This method determines the earliest start and finish dates for each task in the project. It starts at the beginning of the project and works forward to calculate the earliest possible date that each task can begin and end.

  2. Backward Pass: This method determines the latest start and finish dates for each task in the project. It starts at the end of the project and works backward to calculate the latest possible date that each task can begin and end without delaying the overall project completion date.

The critical path is identified and the project's timeline is guaranteed by combining the forward pass and backward pass procedures. Project managers can recognize potential scheduling issues, change the project schedule, and guarantee that crucial tasks are performed on time by combining the two techniques.

Two Types of Critical Paths

There are two types of critical paths:

The Longest Path: The shortest time required to complete a job is determined by the longest path. It is the sequence of tasks with the longest cumulative duration. The project completion date will be postponed if any of the tasks along this path take longer than they were predicted to.

The Shortest Path: This is the sequence of tasks with the shortest total duration, and represents the best-case scenario for project completion. It is useful for project managers to understand the shortest path because it can help identify opportunities for improving the project schedule by reducing the duration of critical tasks.

The two types of critical paths are determined using the forward pass and backward pass methods of the critical path method (CPM). Project managers use the critical path information to monitor and control the project schedule, making adjustments as necessary to keep the project on track.

  3. Use the "Baselines" feature to save a snapshot of your project schedule at a specific point in time. This feature allows you to compare the current schedule with the original schedule, or with a previous schedule, to see how the project has progressed.

  4. Use the "Reports" feature to generate a wide range of pre-built and custom reports. This feature allows you to create reports that show project progress, resource usage, and other important data in a clear and concise format.

  5. Use the "Global Change" feature to make changes to multiple activities at once. This feature allows you to update the duration, resources, or other data for multiple activities at the same time, saving you time and effort.

  6. Use the "Activity Usage Profile" feature to view the resource usage for a specific activity over time. This feature allows you to see how the resource usage for a specific activity changes over the course of the project.

  7. Use the "EPS" feature to view the project structure by using an organizational breakdown structure. This feature allows you to see how the activities of the project are related to the different levels of the organization.

  8. Use the "Resource Availability" feature to view the available resources over time. This feature allows you to see when resources are available, and when they are already assigned to other activities.

  9. Use the "Custom fields" feature to add custom data fields to the activities. This feature allows you to add specific data fields that are important for your project, and to use them for filtering and grouping activities.

  10. Use the "Earned Value Analysis" feature to measure the project's performance by comparing the actual progress to the planned progress. This feature allows you to see the performance of the project in terms of schedule, cost, and scope, and to make adjustments if needed.
