Which factor must be considered when developing a project schedule?

When developing a project schedule, considering the allocation of resources, task durations, and dependencies is crucial because these elements directly affect the project's timeline and overall success. The allocation of resources includes understanding what materials, equipment, and personnel are required, ensuring that these resources are available when needed. Task durations involve estimating how long each task will take to complete, which is essential for setting realistic deadlines and milestones. Dependencies refer to the relationships between tasks and how the completion of one task may affect the start or completion of another. Recognizing these dependencies helps in avoiding scheduling conflicts and potential delays.

Together, by taking into account the allocation of resources, task durations, and dependencies, project managers can create a more accurate and effective schedule that reflects the realities of the project, leading to better planning and execution. This comprehensive approach helps to ensure that all aspects of the project are aligned and functioning together seamlessly.
