In other words, the ones you really need to worry about to make sure you meet your deadlines.The critical path method, a project management technique created in the 1950s, allows you to identify these important tasks and stay on track throughout your project.Starting as hand-drawn diagrams and evolving into automated software, the critical path method has become an essential part of planning a project.The Project Management Body of Knowledge (PMBOK), an internationally recognized collection of processes and knowledge areas accepted as best practice for the project management profession, defines the critical path as “the sequence of scheduled activities that determines the duration of the project.” It is the longest sequence of tasks in a project plan that must be completed on time in order for the project to meet its deadline.There are a whole bunch of calculations that go into figuring out what-ifs, forecasting, and scheduling, but that's where project management software comes in and makes everyone's lives easier.
It is best used when you have multiple branches, or multiple entry points, for an activity.
It identifies tasks that are critical, time-wise, in completing the project. Larry Bennett, a civil engineer, project manager, and author of four books, including a guide on critical path written in 1978 and titled, “Critical Path Precedence Networks,” explains that the critical path method helps manage projects in two different ways: “It produces a planned schedule to guide the project team, and it forms the basis for tracking project schedule performance by comparing actual with planned task progress.”We asked two critical path users for the best way to explain it.
Here's what they had to say: "The critical path is just a fancy way of saying ' How long does each task take before you can finish the project?
You’ll need to be able to draw a network diagram, identify the critical path, use the Forward Pass/Backward Pass technique, and calculate slack.
Here is an overview of the most important things to know about the critical path method to help you pass the PMP exam: On the PMP Exam, you will be asked to draw a network diagram.
