Exam 3: Project Management

The network below represents a project being analyzed by the critical path method.Activity durations are A=5,B=2,C=12,D=3,E=5,F=1,G=7,H=2,I=10,and J=6. a.What task must be on the critical path,regardless of activity durations? b.What is the duration of path A-B-E-H-J? c.What is the critical path of this network? d.What is the length of the critical path? e.What is slack time at activity H? f.What is the Late Finish of activity H? g.If activity C were delayed by two time units,what would happen to the project duration?

The beta distribution is used in project management to:

The difference between AON and AOA networks is that:

Match the following steps in Microsoft's development of Windows 8 to their respective WBS level.

The critical path for the network activities shown below is ________ with duration ________.

Describe some of the challenges faced in the construction of the new 11-story building at Arnold Palmer Hospital in Orlando,Florida.

Ethical issues that may arise in projects large and small include:

How is the expected completion time of a project activity,and of a PERT project,computed?

Which of the following statements regarding CPM is true?

Which of the following statements concerning CPM activities is false?

The PERT pessimistic time estimate is an estimate of the minimum time an activity will require.

A project organization:

Contract requirements state that a project must be completed within 180 working days,or it will incur penalties for late completion.Analysis of the activity network reveals an estimated project time of 145 working days with a project variance of 400.What is the probability that the project will be completed before the late-payment deadline?

The ________ distribution is appropriate for calculating expected activity times and activity variances in PERT networks.

What is a project organization?

Two critical path activities are candidates for crashing on a CPM network.Activity details are in the table below.To cut one day from the project's duration,activity ________ should be crashed first,adding ________ to project cost.

What are the three phases of a project? Describe each in a sentence or two.

Explain why the critical path is the longest,not the shortest,path through a network.

A project whose critical path has an estimated time of 820 days with a variance of 225 has a 20% chance that the project will be completed before which day (rounded to nearest day)?

Three critical path activities are candidates for crashing on a CPM network.Activity details are in the table below. a.What is the crash cost per unit time for activity A? b.What is the crash cost per unit time for activity B? c.Which activity should be crashed first to cut one day from the project's duration; how much is added to project cost? d.Which activity should be the next activity crashed to cut a second day from the project's duration; how much is added to project cost? e.Assuming no other paths become critical,how much can this project be shortened at what total added cost?
