What is the primary purpose of 'fast tracking' in project management?

The primary purpose of 'fast tracking' in project management is to complete more activities concurrently. Fast tracking involves overlapping phases or tasks that would traditionally be completed sequentially, thereby reducing the overall project duration. This technique allows project managers to compress schedules without necessarily increasing resources, sometimes resulting in significant time savings.

By employing fast tracking, teams can identify tasks that can be performed simultaneously, which can be especially beneficial in time-sensitive projects. However, it may lead to increased risks and management challenges, as overlapping activities may complicate coordination and communication among teams.

The other options, while related to project management, do not capture the essence of fast tracking. Increasing overhead costs and improving time estimation accuracy are not direct outcomes of this strategy. Similarly, assessing resources needed for each task is part of project planning but does not pertain to the primary goal of executing tasks concurrently through fast tracking.
