CompTIA Project+ (PK0-005)Project Life Cycle PhasesMedium
A project manager is developing the project schedule and identifies that a specific activity, 'Software Module Testing,' has some flexibility and can be delayed by up to five days without affecting the project's overall completion date. What term describes this flexibility?
- AFast Tracking
- BLag Time
- CCritical Path
- DFloat (Slack)
Show answer & explanationAnswer & explanation
Correct answer: D. Float (Slack)
Float, also known as slack, is the amount of time an activity can be delayed without delaying the project end date or violating a schedule constraint. It represents the scheduling flexibility available for an activity.
Why the other options are wrong
- A. Fast Tracking is a schedule compression technique, not a measure of flexibility.
- B. Lag Time is a delay between activities, not the flexibility of a single activity.
- C. Critical Path is the sequence of activities with zero float, where any delay impacts the project end date.
Float (Slack)
The amount of time an activity can be delayed without delaying the project end date or violating a schedule constraint.
- Indicates scheduling flexibility.
- Activities on the critical path have zero float.
- Can be total float or free float.
Memory trick: Float is like a 'breather' in the schedule, a 'cushion' for tasks.
