Which of the following is not typically treated as part of a project life cycle?

What is the probability that the critical path for this project will be completed within 200 days?

In order to determine the probability of timely project completion, it is sometimes necessary to take into account paths other than the critical path.

The standard deviation of the critical path is equal to the sum of the standard deviations of all of the activities on the critical path.

What is the estimated expected (mean) time for project completion?

The optimum project length in crashing occurs where the cumulative cost of crashing equals savings in the indirect costs.

Project management differs from management of more traditional activities mainly because of:

Project managers are sometimes able to reduce indirect project costs by increasing direct costs.

Prepare a crashing plan for the following project that will reduce the project duration by three weeks.

Many activities have slack time; if we add these slack times together, this represents the potential improvement in early completion for the project.

The sum of times of the longest path in a network indicates expected project completion time, and the activities represent the critical activities.

A hierarchical (vertical) listing of what must be done during a project is called matrix.

Consider the project depicted by the following A-O-A diagram:

If the expected length of a path is more than 2.5 standard deviations less than a desired project completion time, the path would not be a factor in assessing the probability of finishing the project on time.

Which of the following is not an element of the project management triangle?

What is the estimated expected (mean) time for project completion?

Given the network diagram below, determine the probability that the project will finish within 26 weeks of its start.Times on the diagram are in weeks.
