Question:medium

Which of the following is the "amount of time" by which the "start of an activity" may be delayed without delaying the "start of a following activity"?

Show Hint

Free float is always less than or equal to total float, and it ensures no delay to successor activities.

  • Interference float
  • Free float
  • Independent float
  • Total float
Show Solution

The Correct Option is B

Solution and Explanation

Phase 1: Review float classifications.
- Total float: The maximum extension of an activity's duration without impacting the overall project end date.
- Free float: The permissible delay for an activity without pushing back the start date of its immediate successor.
- Independent float: The float available when the preceding event is at its latest possible time and the succeeding event is at its earliest possible time.
- Interference float: The segment of total float that, if consumed, will inevitably postpone the subsequent activities.

Phase 2: Application to the query.
The question explicitly asks for the "delay of start of activity without delaying start of following activity." This statement precisely matches the definition of free float.

Phase 3: Determination.
The accurate response is Free float.
