In project scheduling using the Critical Path Method, what is the inherent characteristic of any activity located on the critical path regarding its total float?

The inherent characteristic of any activity located on the critical path regarding its total float is that its total float is always zero. Total float, sometimes referred to as total slack, represents the maximum amount of time an activity can be delayed from its early start date without delaying the entire project's completion date or violating a schedule constraint. The Critical Path Method (CPM) is a project scheduling technique used to identify the longest sequence of activities in a project network that must be completed on time for the project to finish by its earliest possible date; this sequence is known as the critical path. An activity, in this context, is a distinct, scheduled piece of work that consumes time and resources. Because the critical path determines the shortest possible duration for completing the entire project, any delay to an activity that is part of this longest sequence would directly extend the project's overall completion date. Consequently, activities on the critical path possess no available buffer or flexibility in their schedule, meaning their total float is precisely zero, indicating that any delay in these specific activities will directly result in a corresponding delay to the project's final delivery date.
