A PERT/CPM activity has an optimistic time estimate of three days, a most likely time estimate of eight days, and a pessimistic time estimate of 10 days. The expected time (in days) of this activity is

Activities not on the critical path have a slack time equal to zero.

Which of the following is determined as a direct result of computing the earliest starting and finishing times for the activities of a project network?

A popular visual tool for planning and scheduling simple projects, and for monitoring progress, is the

A method used for establishing a logical framework for identifying the required activities for the project is called

Slack time is equal to LS-ES or LF-EF.

Consider the following work breakdown structure: What is the estimated expected (mean) time for activity E?

Which of the following is not a limitation of PERT and similar project-scheduling techniques?

Consider the following work breakdown structure: What is the estimated expected (mean) time for project completion?

Project management software eliminates constraint violations when there are shared resources.

One way that project management differs from management of more traditional activities is because of the limited time framework of projects.

Activity J has a duration of 7 and an earliest finish time of 21. If J's latest start time is 16, this must mean that J's slack is

A project is represented by the following diagram: The critical path for the network shown is:

Although PERT and CPM were originally developed independently, they are now nearly identical in terms of analysis and procedures.

In a project network, the critical path is the sequence of activities which has the

The probability of occurrence of risk events is lower near the beginning of a project and higher near the end of the project since very few activities remain.

Consider the following work breakdown structure: What is the estimated slack time for activity D?

Consider the following work breakdown structure: What is the estimated expected (mean) time for project completion?
