There are four activities on the critical path, and they have standard deviations of 1, 2, 4, and 2 days.The standard deviation of the critical path is:

The probability that the project will go beyond the desired time is equal to one minus the joint probability that all paths will be completed within the desired time.

In crashing this project to 18 weeks, which activities (in order of selection) will be reduced? A.

The task of identifying risks should involve everyone associated with the project.

The total cost of crashing any one activity should never exceed 20% of the total cost of the original project.

Most likely time generally is more than optimistic time.

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

The critical path for the network shown is:

If two consecutive activities on the same path each have two days of activity slack, this means that each of them can be delayed by two days without delaying the project.

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

Given this information about activity 3-4: ES = 10, EF = 15, LS = 16, and LF = 21, we can determine that the amount of slack associated with the activity is:

In PERT, the path with the fewest activities is referred to as the critical path.

If an activity is determined to be on the critical, that means that it, and perhaps other, will affect project ____________.

Activity C has an early start time of 8, an early finish time of 12, a latest start time of 13, and a latest finish time of 17.Its slack is:

What is the estimated slack time for activity W?

What is the estimated standard deviation in the time for activity E?

To _____ an activity means to shorten the time it will take.

What is the estimated standard deviation in the time for activity D?
