You have created the project network diagram for the ABC project. You are exploring total float
and free float for that project. Martin, a project team member, wants to know the difference
between total float and free float. What is the difference between total float and free float?
A.
Total float is the amount of time an activity can be delayed without delaying any project
successors, whereas free float is the amount of time an activity can be delayed without delaying
the project completion date.
B.
Total float is the amount of time an activity can be delayed without delaying the project
completiondate, whereas free float is the amount of time an activity can be delayed without
delaying any project successors.
C.
Total float is the amount of time an activity can be delayed without delaying the project
completiondate, whereas free float is the amount of time an activity can be delayed without
delaying any project predecessors.
D.
Total float is the amount of time a non-critical activity can be delayed without delaying any
project successors, whereas free float is the amount of time an activity can be delayed without
delaying the project completion date.
Explanation:
Total float is the time you can delay an activity without delaying the project end date, whereas free
float is on each activity and does not affect the early start date of successor activities. Float, also
called slack, is the amount of time an activity can be delayed without affecting any subsequent
activities. There are two types of floats available: Free Float: It is the amount of time a schedule
activity can be delayed without delaying the early start date of any immediately following schedule
activities. Total Float: It 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 schedule constraint. Float is
calculated by using the critical path method technique.
Answer options C, A, and D are incorrect. These are not accurate definitions of free float and total
float.
