Which of the following allows activities to be done in parallel that would normally be done in
sequence?

A.
Lag time

B.
Lead time

C.
Fast tracking

D.
Crashing

Explanation:
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.
