Which of the following allows activities to be done in parallel that would normally be done in
equence?
Fast tracking is a technique for compressing project schedule. In fast tracking, phases
are overlapped that would normally be done in
sequence. It is shortening the project schedule without reducing the project scope.
Answer option D is incorrect. Crashing is a process in that the project manager adds more resources
to effort-driven activities in an attempt to
shorten their duration.
Answer option A is incorrect. 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 B is incorrect. A lead time is the time that overlaps between the predecessor and the
successor tasks. The successor task can
start before the predecessor task finishes. For example, if a task can start when its predecessor is
one-fourth finished, a finish-to-start
dependency with a lead time of 25 percent for the successor task can be specified. The lead time is
entered as a negative value. The lead 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.
