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

You are concerned about a risk on Activity G that if it happens will delay the project by four days.
You would like to utilize float for Activity G. How much float is available for Activity G to help offset
the risk event?

A.
Five days

B.
Four days

C.
Eleven days

D.
Zero

Explanation:
There is no float available for Activity G because it is on the critical path. 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.
Answer options B, A, and C are incorrect. There is no float available for Activity G because it is on
the critical path.
