Question

The time by which activity completion time can be delayed without affecting start of succeeding activity

• A. Duration
• B. Free float
• C. Total float
• D. Interfering float

Hint:

Think of the floats in terms of their impact:
- Free Float: Delay impacts NO ONE else. (You are "free" to use it).
- Total Float: Delay impacts SOMEONE else down the line, but not the final project deadline.
- Zero Float: Delay impacts EVERYONE, including the project deadline (Critical Activity).

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks for the specific project management term that defines the amount of delay possible for an activity without impacting the very next activity in the sequence.

Step 2: Detailed Explanation:
Let's define the different types of float:
-

Total Float: This is the maximum amount of time an activity can be delayed without delaying the entire project's completion date.
-

Free Float: This is the amount of time an activity can be delayed without delaying the early start of any immediately following ("succeeding") activity.
This is a subset of Total Float.
It represents the "local" slack an activity has before it starts affecting its neighbours.
This perfectly matches the definition in the question.
-

Interfering Float: This is the difference between Total Float and Free Float.
It is the amount of slack that, if used, will not delay the project but will delay the start of a subsequent activity.

Step 3: Final Answer:
The time by which an activity can be delayed without affecting the start of a succeeding activity is called Free Float.
This corresponds to option (B).
