Exam 9: Project Scheduling: Networks, Duration Estimation, and Critical Path

Use the information in the table to determine the early start time for Activity B.

The amount of time an activity may be delayed from its early start without delaying the finish of the project is the:

There's an old saying, "The job is not finished until the paperwork is done." From an activity network standpoint, this does not necessarily mean that the paperwork can't begin until the last non-paperwork activity is completed. It might be possible to work on some paperwork as early activities are completed. In order to depict this in an activity network:

Draw a network of any size that has at least one of each of the following features: merge activity, burst activity, hammock activity, ladder activity, critical path, serial activities, concurrent activities, and float. Mark these features on your network.

A sequence of activities defined by the project network logic is a(n):

The least amount of float is found:

Serial activities are those that:

What is the early finish time for Activity F given the activity times and precedence requirements shown in the table?

What are hammock activities and when should they be used?

What does a network diagram illustrate and why are they important in project management?

Use the information in the table to determine the slack time for Activity B.

What is the slack time for activity E?

Ray's shipment of materials hit every red light and traffic jam on the way to the site. Upon arrival, half of the material was judged defective, necessitating a trip back to the supplier, and then the same arduous journey back to the site once the new materials were loaded. Traffic was a little better on the second round but the flat tire and subsequent repair caused as much if not more delay than the first trip. In the final analysis:

A gentleman farmer maniacally works on academic projects to raise funds for his true passion, farming. He has identified seven tasks and developed three time estimates (all in days) of the next big project on the farm, replacing the fence at the comedy pasture. Tasks, precedence requirements, and time estimates are shown in the table. What is the probability that the project takes more than 34 days?

An activity has an optimistic time estimate of 17 days, a most likely estimate of 22 days, and a pessimistic estimate of 32 days. What is the expected duration of the activity?

An activity has an expected duration and an expected cost. Another name for an activity is a(n):

Which technique would accelerate the completion of a project?

Activity float is the difference between the late finish and early finish for the activity in question.

What is the float start time for Activity C given the activity times and precedence requirements shown in the table?

Use the information in the table to determine the early finish time for Activity D.
