According to the Project Management Body of Knowledge (PMBOK), a project manager should ensure that all relevant stakeholders, including subject matter experts (SMEs), have contributed to the schedule development. This ensures that the schedule is realistic and takes into account all necessary tasks and dependencies. Additionally, evaluating the schedules for interdependencies to establish the critical path is crucial in project management. The critical path method is a step-by-step project management technique to identify activities on the critical path. It is an approach to project scheduling that breaks the project into several work tasks, displays them in a flow chart, and then calculates the project duration based on estimated durations for each task. References: PMBOK Guide, 6th Edition, Section 6.3: Sequence Activities and Section 6.4: Estimate Activity Durations.
