Exam 11: Project Management

Which of the following statements about project crashing is false?

Consider the tasks, durations, and predecessor relationships in the following network.Draw the network and answer the questions that follow. (a)What is the expected duration of the project? (b)What is the probability of completion of the project before week 42?

Given the following small project, the critical path is ________ days.

PERT stands for

Table 11-8 A mad scientist has identified the ten steps required to create a race of atomic supermen to complete his plans for world conquest.The estimated time in weeks and cost in US dollars appear in the table along with the shortest possible duration for each activity and cost of those expedited activities.Activities are designated generically as A, B, and so on in order to avoid any copycat projects of this nature. -Consider the project summarized in Table 11-8.Suppose in addition to the costs shown in the table, the mad scientist faces a $2,000 per week opportunity cost of not being in control of the world.Which of these activities should be crashed in an effort to deliver a minimum cost (both project and opportunity cost)project?

The first step in planning and scheduling a project is to develop the

In PERT/CPM, what is meant by the critical path?

Table 11-2 The following represents a project with four activities.All times are in weeks. -According to Table 11-2, there are four activities in the project.Assume the normal distribution is appropriate to use to determine the probability of finishing by a particular time.What is the probability that the project is finished in 16 weeks or fewer? (Round to two decimals.)

Consider a project that has an expected completion time of 60 weeks and a standard deviation of five weeks.What is the probability that the project is finished in 70 weeks or fewer? (Round to two decimals.)

CPM stands for

The process of smoothing out the utilization of resources in a project is called

Table 11-4 The following represents a project with known activity times.All times are in weeks. -Using the data in Table 11-4, compute the latest finish time for activity E.

Table 11-5 -How long could Table 11-5's activity E be delayed without delaying the completion of the project?

The crash time of an activity represents

Table 11-4 The following represents a project with known activity times.All times are in weeks. -Using the data in Table 11-4, determine the latest time activity A can be finished and not delay any activity?

Given: Determine: (a)the critical path. (b)the probability that the project will be completed in 22 weeks.

Your company is considering submitting a bid on a major project.You determine that the expected completion time is 100 weeks and the standard deviation is 10 weeks.It is assumed that the normal distribution applies.You wish to set the due date for the project such that there is an 85 percent chance that the project will be finished by this time.What due date should be set?

PERT stands for Probabilistic Evaluation and Review Technique.

A small software development project has four major activities.The times are estimated and provided in the table below. (a)What is the expected completion time for this project? (b)What variance would be used in finding probabilities of finishing by a certain time?

The project described by has a critical path length of:
