Which scheduling technique involves reducing the project timeline by overlapping tasks?

Fast tracking is a scheduling technique that focuses on reducing the overall timeline of a project by allowing tasks that were originally planned to be performed sequentially to be completed in parallel, or overlapped. This approach aims to expedite project completion by optimizing the scheduling of activities, thereby taking advantage of any opportunities to overlap tasks that can be run concurrently.

This method is particularly useful in projects where time is of the essence, but it does carry risks, as overlapping may lead to increased complexities and potential delays if tasks are not properly coordinated.

On the other hand, time lag refers to a delay between dependent tasks, which does not involve overlapping tasks but rather spaces them out. The Critical Path Method is aimed at identifying the longest stretch of dependent activities and measuring the time required to complete them, but it does not inherently involve overlapping tasks, as it focuses on task sequencing. Time management encompasses a broader set of practices related to effectively planning and controlling the amount of time spent on specific tasks, rather than the specific technique of overlapping tasks.
