Exam 3: Project Management

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?

Gantt charts give a timeline for each of a project's activities,but they do not adequately illustrate the interrelationships between the activities and the resources.

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?

Agile project management is a type of work breakdown structure (WBS).

Which of the following is NOT performed by Microsoft Project?

Given the critical path below,calculate the following: a.The crash cost per unit time savings for each activity. b.The maximum total crash time savings and cost. c.The maximum total time-savings with a $3000 budget.

Which of the following statements regarding CPM is true?

Which of the following statements regarding CPM networks is true?

Consider the network presented in the following table.Calculate a.All possible paths b.The critical path c.The slack available at any non-critical points d.The minimum project duration

Which of the following statements regarding Gantt charts is true?

The beta distribution is used in project management to:

Slack is the amount of time an activity can be delayed without delaying the entire project.

The waterfall approach is used most often for:

A simple CPM network has five activities,A,B,C,D,and E.A is an immediate predecessor of C and of D.B is also an immediate predecessor of C and of D.C and D are both immediate predecessors of E.Which of the following statements is true?

PERT,but not CPM,has the ability to consider the precedence relationships in a project.

Define slack time.

An activity on a PERT network has these time estimates: optimistic = 2,most likely = 5,and pessimistic = 10.What is its expected activity time?

In PERT analysis,the identification of the critical path can be incorrect if a noncritical activity takes substantially more than its expected time.

A partially solved PERT problem is detailed in the table below.Times are given in weeks. a.Calculate the expected time for each activity.Enter these values in the appropriate column in the table above. b.Which activities form the critical path? c.What is the estimated time of the critical path? d.What are the project variance and the project standard deviation? e.What is the probability of completion of the project after week 40?

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