What is a Critical Path Schedule?
It’s a schedule that identifies the absolute must-do tasks that determine your project’s finish date. It shows you the chain of jobs that can’t afford any delays.
Why do I need to know the "Critical Path"?
It tells you exactly where to focus your energy and resources. If a task on the critical path is delayed, your whole project is delayed. It stops you from worrying about non-urgent tasks and helps you avoid costly overruns.
