CAPM Practice: Demonstrate an understanding of a project management plan schedule

Total float = time an activity can be delayed without delaying the project end date. Free float = time an activity can be delayed without delaying any of its immediate successor activities. Free float is always ≤ total float. Free float delay affects only the current path; total float delay affects the overall project end.

**Why not A:** Free float is always less than or equal to total float, never larger. Total float considers the entire path to the project end, while free float only considers the immediate successor. The constraint for free float is tighter, so the value is smaller or equal.

**Why not B:** Critical path activities have zero total float and zero free float. Free float is a concept for non-critical activities that have scheduling flexibility. It is not exclusive to or specifically associated with the critical path.

**Why not C:** Free float is a scheduling concept used in predictive projects that employ the Critical Path Method. It is not limited to agile projects. In fact, float calculations are a fundamental part of CPM scheduling in predictive methodology.
