Question
Assume that activity P has the following times:
Early start time (ES) = 4 days
Early finish time (EF) = 11 days
Latest start time (LS) = 6 days
Latest finish time (LF) = 13 days
Which of the following statements is TRUE about activity P?
a. Activity P takes 2 days to complete
b. Activity P is on the critical path
c. Activity P has 2 days of slack time
d. Activity P is the first activity of the project
e. None of the above are true
Assume that activity P has the following times:
Early start time (ES) = 4 days
Early finish time (EF) = 11 days
Latest start time (LS) = 6 days
Latest finish time (LF) = 13 days
If disaster strikes and activity P will take 20 days to complete rather than the original activity duration (assume that it started at the ES time), by how long will the completion of the project be delayed?
a. 20 days
b. 13 days
c. 11 days
d. 7 days
Explanation / Answer
1.
(ES) = 4 days
(EF) = 11 days
(LS) = 6 days
(LF) = 13 days
Slack = LF - EF or LS - ES
= 13 - 11 = 2
c. Activity P has 2 days of slack time
2.
Earlier Activity Duration = EF - ES = 11 - 4 = 7 days
If disaster strikes and activity P will take 20 days to complete rather than the original activity duration.
by (20 - 7) = 13 days will take for completion of the project be delayed.
b. 13 days
