Understanding the project scope is a foundational step in creating an effective project schedule. A clear grasp of the project's objectives and deliverables enables the creation of a work breakdown structure (WBS), breaking down the scope into manageable tasks. This structured breakdown forms the basis for scheduling activities, allowing project managers to assign durations and dependencies to each work package. A well - defined project scope serves as a guide throughout the scheduling process, ensuring that all necessary tasks are identified and sequenced logically .
