If you are the project manager of the BNQ Project and you add "waiting time" between two
activities, then what have you added in the project?
Lag time is positive time that requires the successor activity to wait for a defined
amount of time, such as three days, before it can begin. Lag
time does not change the task relationship, but requires a 'waiting time' before the starting of the
activity can begin.
A lag time is a delay between the predecessor and the successor tasks. Sometimes it may be needed
to schedule a delay between the
predecessor and the successor tasks. For example, if two coats of paint are required to paint a car,
then the final coat should be applied only
when the first coat dries. This delay is known as the lag time. The lag time is entered as a positive
value. The lag time can be entered as a
duration or as a percentage of the predecessor's task duration. It is entered on the Predecessor tab
in the Task Information dialog box.
Answer option D is incorrect. Float is a natural event that is discovered through the forward pass
when using the critical path method. Float
cannot be arbitrarily added as lag.
Answer option C is incorrect. Lead time actually brings activities closer together and causes them, in
some cases, to overlap.
Answer option B is incorrect. Management reserve is a pool of time allotted for unscheduled
changes and events that affect the project
duration.
