What result can occur if one task in a project schedule is delayed?

When one task in a project schedule is delayed, it can often cause subsequent tasks to also be delayed. This happens because many tasks in a project are interdependent, meaning the start or completion of one task is reliant on the progress of another.

For example, if a foundation needs to be poured before framing can begin, any delay in pouring the foundation will automatically lead to a delay in framing. This cascading effect can ripple through the project schedule, impacting deadlines and possibly affecting the overall project timeline and resource allocation. Therefore, the correct answer highlights the interconnected nature of tasks in project scheduling, where delays in one area can have far-reaching implications on the entire project.

The other options fail to recognize these interdependencies: one task being impacted does not necessarily mean only that task is affected, nor does it imply that all subsequent tasks will remain unaffected or that there would be no impact on project completion.
