which day (rounded to nearest day)?A) 98B) 112C) 120D) 124E) 220.
Answer: B) 112
◍ (T/F)Ill-defined projects are typified by software development and new
technology..
Answer: TRUE
◍ The ________ is the computed longest time path(s) through a network..
Answer: Critical path
◍ The network analysis method that allows activity times to vary is
________..
Answer: PERT or Program Evaluation and Review Technique
◍ ________ is decreasing activity time in a network to reduce time on the
critical path so total completion time is reduced..
, Answer: Crashing
◍ Which of the following statements regarding CPM networks is true?A)
There can be multiple critical paths on the same project, all with different
durations.B) The early finish of an activity is the latest early start of all
preceding activities.C) The late start of an activity is its late finish plus its
duration.Which of the following statements regarding CPM networks is
true?D) If a specific project has multiple critical paths, all of them will have
the same duration.E) None of the above are true..
Answer: D) If a specific project has multiple critical paths, all of them will
have the same duration.
◍ The waterfall approach is used most often for:A) well-defined projectsB)
projects whose changes tend to be minorC) projects with step-by-step
progressD) controlling projectsE) all of the above.
Answer: e. all of the above
◍ (T/F)Agile project management is a type of work breakdown structure
(WBS)..
Answer: FALSE
◍ Which of these statements regarding time-cost tradeoffs in CPM networks is
true?A) Crashing is not possible unless there are multiple critical paths.B)
Crashing a project often reduces the length of long-duration, but noncritical,
activities.C) Activities not on the critical path can never be on the critical
path, even after crashing.D) Crashing shortens the project duration by
assigning more resources to one or more of the critical tasks.E) The crash
time always exceeds the normal time..
Answer: D) Crashing shortens the project duration by assigning more
resources to one or more of the critical tasks.
◍ A combination of effective Gantt chart use and other tactics allowed Delta
to cut the average time for a plane layover by what % of the original 60
minute duration?A) 33%, to 40 minutesB) 50%, to 30 minutesC) 20%, to 48
minutesD) 25%, to 45 minutesE) 40%, to 36 minutes.
Answer: A. 33% to 40 minutes
, ◍ Activity R on a CPM network has predecessors M and N, and has successor
S. R has duration 5. N's late finish is 18, while M's is 20. S's late start is 14.
Which of the following is definitely true?A) R is critical and has zero
slack.B) R has no slack but is not critical.C) The set of times cannot all be
possible.D) N is a critical activity.E) S is a critical activity..
Answer: C) The set of times cannot all be possible.
◍ PERT calculations typically include the duration variance of each activity.
What is the purpose of this calculation, i.e. what's the role of variances in
PERT analysis?.
Answer: The activity variances influence the probability of project
completion. Specifically, the sum of the variances of the critical tasks equals
the variance of the project. Further, large variances on noncritical tasks need
to be monitored. Such an activity might have an actual completion time so
large that the task becomes a critical task.
◍ Describe the differences between a Gantt chart and a PERT/CPM network..
Answer: The differences between a Gantt chart and a PERT/CPM network
are mainly that PERT/CPM has the ability to consider precedence
relationships and interdependence of activities.
◍ Explain why the critical path is the longest, not the shortest, path through a
network..
Answer: The critical path is that set of activities in a project network that
controls the duration of the entire project. The controlling element to
completion of all activities is the longest path; any shorter path will not
allow for all activities to be completed.
◍ The ________ distribution is used by PERT analysis to calculate expected
activity times and variances.A) NormalB) BetaC) AlphaD) GaussianE)
Binomial.
Answer: B) Beta
◍ (T/F)Every network has at least one critical path..
Answer: TRUE
