If a project has no float time, what does that indicate?

When a project has no float time, it indicates that there is no leeway or extra time allocated for particular tasks. This means that if any tasks are delayed, they can directly impact the overall project timeline. In this context, "float" refers to the amount of time that a task can be delayed without affecting the subsequent tasks or the project's completion date.

Projects characterized by zero float are typically on a critical path where each task's timing is essential for maintaining the overall schedule. Therefore, if a task runs late, there is no flexibility to compensate for that delay, which may lead to project completion being jeopardized. This underscores the importance of careful scheduling and resource allocation to prevent potential delays from impacting the overall project timeline.
