Why is identifying dependencies crucial in project scheduling?

Identifying dependencies is crucial in project scheduling because they affect the order and timing of tasks, thereby influencing the project's overall completion. Dependencies highlight the relationships between different tasks, indicating which activities need to be completed before others can begin. This relationship is essential in developing a realistic schedule, as it ensures that all prerequisites for task completion are met, preventing delays and ensuring that the project flows smoothly from one phase to the next.

Understanding these dependencies allows project managers to effectively allocate resources, optimize task sequences, and anticipate potential bottlenecks in the workflow. As a result, accurate identification of dependencies leads to a more robust schedule, better resource management, and ultimately, a higher likelihood of completing the project on time and within scope. This highlights why option B is the correct choice, linking dependencies directly to the timing and success of project completion.
