Exam 3: Project Management

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 22. Which of the following is definitely TRUE?

An activity on a PERT network has these time estimates: optimistic = 3, most likely = 5, and pessimistic = 10. What is its expected activity time?

Which of the following is NOT performed by Microsoft Project?

Match the following steps in Microsoft's development of Windows 10 to their respective WBS level. Step Level Develop Windows 10 Operating System ? System Testing ? Compatible with Windows 8 ? Develop GUI's ? Module Testing ?

Work breakdown structure is a useful tool in project management because it addresses the timing of individual work elements.

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

One phase of a large project is scheduling.

The beta distribution is used in project management to:

A project whose critical path has an estimated time of 120 days with a variance of 100 has a 20% chance that the project will be completed before which day (rounded to nearest day)?

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

The shortest of all paths through the network is the critical path.

The difference between AON and AOA networks is that:

Define slack time.

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

Ethical issues that can arise in projects include gifts from contractors, pressure to mask delays with false status reports, false reports for charges of time and expenses, and pressure to compromise project quality to meet bonuses or avoid penalties related to schedules.

Describe in words how to calculate a project's standard deviation. What assumption allows that calculation to be accurate?

The expected activity time in PERT analysis is calculated as:

A project being analyzed by PERT has 60 activities, 13 of which are on the critical path. If the estimated time along the critical path is 214 days with a project variance of 100, what is the probability that the project will take less than 224 days to complete?

Which of the following projects was NOT completed by Bechtel?

The network below represents a project being analyzed by the critical path method. Activity durations are indicated on the network. (a) Identify the activities on the critical path. (b) What is the duration of the critical path? (c) Calculate the amount of slack time at activity H. (d) If activity I were delayed by ten time units, what would be the impact on the project duration?
