Exam 3: Managing Projects

A PERT project has 45 activities,19 of which are on the critical path.The estimated time for the critical path is 120 days.The sum of all activity variances is 64,while the sum of variances along the critical path is 36.What is the probability that the project can be completed between days 108 and 120?

A network consists of the following list.Times are given in weeks. a.Draw the network diagram. b.Calculate the expected duration and variance of each activity. c.Calculate the expected duration and variance of the critical path. d.Calculate the probability that the project will be completed in less than 28 weeks.

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?

An activity on a PERT network has these time estimates: optimistic = 1,most likely = 2,and pessimistic = 5.What is its expected activity time?

The ES of an activity that has only one predecessor is simply the EF of that predecessor.

What are the earliest activity start time and latest activity start time,and how are they computed?

A local project being analyzed by PERT has 42 activities,13 of which are on the critical path.If the estimated time along the critical path is 105 days with a project variance of 25,what is the probability that the project will be completed in 95 days or less?

Which of the following statements regarding time-cost tradeoffs in CPM networks is false?

A network consists of the activities in the following list.Times are given in weeks. a.Draw the network diagram. b.Calculate the ES,EF,LS,LF,and Slack for each activity. c.What is project completion time?

A(n)________ is an organization formed to ensure that programs (projects)receive the proper management and attention.

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

Activity D on a CPM network has predecessors B and C,and has successor F.D has duration 6.B's earliest finish is 18,while C's is 20.F's late start is 26.Which of the following is definitely true?

Define slack time.

A(n)________ divides a project into more and more detailed components.

A project organization works best for an organization when the project resides in only one of its functional areas.

Which of the following statements regarding CPM is true?

Pirmin's Bike Shop is behind on a custom bike and needs to crash 8 hours of time from the 8-step project.Given the project table below calculate the crash cost for 8 hours of time-savings.Suppose Pirmin calls the customer and asks for a project extension,reducing the amount of time he needs to crash.Calculate both the maximum time-savings available on a $25 crash budget and the cost to crash four hours of savings.

The ________ has established a code of ethics especially for project managers.

What was the name of the construction project to rebuild the Pentagon after the terrorist attacks on Sept.11,2001?

The ________ is the computed longest time path(s)through a network.
