What do dependencies in schedule components indicate?

Dependencies in schedule components indicate the sequence in which activities take place. Understanding dependencies is crucial in project management, particularly in construction, as they dictate how tasks are interrelated and the order in which they must be completed for the project to proceed efficiently. For example, if one activity must finish before another can start, this creates a dependency that needs to be accounted for in scheduling.

This sequencing ensures that resources are optimally managed and that delays in one task do not cascade into others, jeopardizing project timelines. In addition, recognizing these dependencies helps project managers identify the critical path—essentially the longest stretch of dependent activities that determines the project's minimum completion time. Thus, option B is the correct choice as it directly relates to how project schedules are structured and managed.
