13.1 PERT and CPM are quantitative analysis tools designed to schedule and control large
projects.
ANSWER: TRUE
13.2 PERT is a deterministic analysis tool allowing for precise times of activities within a project.
ANSWER: FALSE
13.3 PERT had its beginnings in a military department of the United States.
ANSWER: TRUE
13.4 CPM is a probabilistic analysis of managing a project.
ANSWER: FALSE
13.5 An event is a point in time that marks the beginning or ending of an activity.
ANSWER: TRUE
13.6 A network is a graphical display of a project that contains both activities and events.
ANSWER: TRUE
13.7 The optimistic time is the greatest amount of time that could be required to complete an
activity.
ANSWER: FALSE
13.8 PERT is a network technique similar to CPM, but PERT allows for project crashing.
ANSWER: FALSE
13.9 The most likely completion time of an activity is used to represent that activity’s time within
a project.
ANSWER: FALSE
13.10 The expected completion time and variance of an activity is approximated by the normal
distribution in a PERT analysis.
ANSWER: FALSE
13.11 PERT was developed for a project for which activity or task times were uncertain.
ANSWER: TRUE
13.12 CPM was developed for use in managing projects which are repeated and about which we
have good information as to activity or task completion times.

ANSWER: TRUE
13.13 With PERT, we are able to calculate the probability of finishing the project on a particular
day.
ANSWER: TRUE
13.14 With CPM, we are able to calculate the probability of finishing the project on a particular
day.
ANSWER: FALSE
13.15 A PERT or CPM network shows activities and activity sequences.
ANSWER: TRUE
13.16 One of the most difficult aspects of using PERT is defining the activities so that they have
measurable/observable starts and finishes.
ANSWER: TRUE
13.17 Before drawing a PERT or CPM network, we must identify each activity and their
predecessors.
ANSWER: TRUE
13.18 The three time estimates employed in PERT are: optimistic time, average time, and
pessimistic time.
ANSWER: FALSE
13.19 In the PERT process, if an activity has zero variance it must be on the critical path.
ANSWER: FALSE
13.20 Given the variability of the activity completion time, the original critical path we identify in
our PERT analysis may not always be the actual critical path as the project takes place.
ANSWER: TRUE
13.21 In PERT, the activity completion times are modeled using the beta distribution.
ANSWER: TRUE
13.22 In PERT, the earliest finish time in one activity will always be the earliest start time of the
following activity.
ANSWER: FALSE
13.23 In PERT, the earliest start time for an activity is equal to the latest of the earliest finish times
of all of its immediate predecessors.
