Float (also known as slack) in a project schedule refers to:

Show answer & explanation

Correct answer: The amount of time an activity can be delayed without delaying the project end date

Explanation

Float (or slack) is the amount of time a non-critical activity can be delayed without affecting the project's overall completion date or a successor milestone. Activities on the critical path have zero float. Float represents schedule flexibility for non-critical activities.

**Why not A:** While schedule buffers may be added to account for risk, float is not an intentionally added buffer. Float is calculated through the Critical Path Method as the difference between early and late schedule dates. It is a mathematical result of network analysis, not a deliberate risk provision.

**Why not B:** Extra resources assigned to critical path activities describe resource loading or crashing decisions. Float is a time-based scheduling concept that measures schedule flexibility, not a resource allocation strategy.

**Why not D:** The time difference between planned and actual completion describes schedule variance or slippage. Float is a forward-looking planning metric calculated before work begins, not a measure of actual performance deviation.
