PMI-SP Exam - Topic 3 Question 58 Discussion

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.
