Fast tracking is an example of which type of project relationship?

Fast tracking is a project management technique where tasks that were originally planned to be completed in sequence are instead performed in parallel, thereby overlapping their schedules. This approach can help in shortening the overall project duration. By overlapping activities, project managers can better utilize resources and time, which can be particularly valuable in situations where deadlines are tight or delays need to be minimized.

In contrast, the other types of project relationships establish clear distinctions in how tasks relate to one another. Sequential relationships involve tasks that must be completed one after the other, with each task dependent on the completion of the previous one. Dependent relationships highlight that one task's start or finish is contingent upon another's completion, while independent relationships describe tasks that do not affect one another’s timelines. Fast tracking specifically leverages overlapping to enhance efficiency and speed, making it distinct from these other relationships in project management.
