It’s tempting to think of dependencies in a strictly linear fashion, yet that’s rarely the case.ĭependencies are often a more complicated relationship. For example, you can’t launch a new Facebook ad campaign without a completed landing page. Understanding the building blocks of PERT helps teams better manage projects, regardless of method.Ī dependency is when one task or project activity can’t happen without a related activity being kicked into motion first. ![]() In PERT charts, the critical path is often highlighted by position (in the center) or with a different color. It shows the relationship between tasks as well as the overall project duration. The PERT technique was designed as a statistical tool to visualize the overall project schedule, not just the critical path. In fact, project managers often use the PERT chart to show the critical path, which is why the two sometimes get confused. Visualization is not necessary, although it is helpful, and often used as part of the process. It works by analyzing the longest stretch of dependent activities. In project management, the critical path method (aka CPM), is a way to calculate the longest “path” or duration until a project is finished. Focus on deliverables rather than the required tasks will ensure the flowchart doesn’t become a nightmare of lines and bubbles. The PERT framework can also be used for large-scale projects.įor a longer and more complex project, replace days with weeks or months and split activities into larger groups. So, the team responsible for that activity doesn’t need to start work until 8 days into the project (2 days for Task 1 plus 6 days for Task 2). The lines show order, duration, and dependencies.įor example, you can’t start activity 6 until both 2 and 4 are completed. The numbers (1-8, in this case) help identify the tasks. It’s useful during the early stages of planning when sorting through how all the pieces go together.įor example, a project with 7 key activities and a total project duration of 14 days, could have a chart that looks like this:ĭoes it feel like you’re staring at a Jackson Pollock painting?ĭon’t worry, it’ll make more sense as you read on. Program Evaluation and Review Technique, or PERT, is a way to estimate the total duration of a project … especially effective for projects with many moving parts and dependencies.Ī PERT chart helps visualize a project schedule or timeline as a flowchart. This article l cover what PERT is, how to effectively use it, and alternatives that better suit certain use cases. PERT is a framework to map out task dependencies and estimate how long a project will last. In 1957, while secretly creating nuclear submarines, the United States Navy developed a technique called PERT (Program Evaluation and Review Technique).įast forward 65+ years later and PERT is still a popular project management tool today. Q: What do a project management system and nuclear submarines have in common? ![]()
