The time by which the completion of an activity can be delayed without affecting the start of succeeding activity is called
- ATotal float
- BInterfering float
- CIndependent float
- DFree floatCorrect
Solution
Concept
Definition of free float in scheduling
Formula
NONE
Step-by-step solution
1. Total float is the total time by which an activity can be delayed without delaying project completion. 2. Free float is the portion of total float by which an activity can be delayed without delaying the early start of any succeeding activity. 3. Therefore, free float directly measures flexibility that does not affect following activities. Answer: D
Explanation
Free float is defined as the maximum time an activity can be delayed without delaying the early start of any succeeding activity. Unlike total float, which impacts the overall project completion date, free float is restricted to the specific task without disturbing subsequent schedules. Therefore, free float accurately describes this allowable delay.
Why the other options are wrong
A) Total float is the delay allowed without affecting the overall project completion date. B) Interfering float is the part of total float that consumes the float of succeeding activities. C) Independent float is the delay possible without affecting preceding or succeeding activities.
Shortcut
Free Float = delay without delaying the start of succeeding activities.
Common mistake
Confusing free float with total float, which affects overall project duration rather than just succeeding activities.
Correct answer: D) Free float
