You are the project manager of the NHQ Project. You have created the project network diagram as shown in the figure:
//IMG//

Based on the project network diagram, how much float is available for Activity H if Activity B is delayed by four days and Activity D is delayed by two days?

## Correct Answer

_See scenario._

## Explanation

The path of ABDHJ will take 21 days to complete and cannot exceed 27 days or else the project will be late. If Activity B takes four additional days and Activity D takes two additional days, this adds (4+2= 6) six days to the path, bringing the path's duration to exactly (21+6 = 27) twenty seven days. There is no available float left for Activity E or H. Float or total float (TF) is the total amount of time that a schedule activity may be delayed from its early start date without delaying the project finish date, or violating a schedule constraint. It is calculated by using the critical path method technique and determining the difference between the early finish dates and late finish dates.
Incorrect Answers:
A, B, C: There is no float available because the path's duration has increased to 27 days.
