The easiest way to add more labor to a project is not to add more people, but to schedule overtime. What are the disadvantages of scheduling overtime?

Incentive contracts can make the reduction of project time rewarding-usually for both the project contractor and owner.

Cost slope can be determined by dividing the

What does it mean to say that a project network is sensitive and why is that important to a project manager who needs to reduce the duration of his or her project?

Helen has just learned that she needs to reduce the duration of her project to meet an imposed deadline. She has calculated the crash cost per unit and knows the maximum units each activity can be reduced. What is the next step?

Insensitive networks are a rarity; Planning for a sensitive network is more practical.

An activity's normal time and cost are 12 and $150, respectively. Its estimated crash time and cost are 9 and $300, respectively. This activity's crash cost per time unit is ________.

An activity must be crashed on each critical path in order to reduce project duration.

Consider the following table of activities that describes a project network. Without causing the critical path to become noncritical or otherwise wasting money, by how many days max could you crash this project? Assume you can crash only one activity at a time and that crashing is necessary regardless of cost. You do not want to crash the critical path(s) beyond the point where it (they) is no longer critical as this will not reduce project duration.

Consider the following table of activities that describes a project network. Is this network sensitive? Suppose indirect costs are $550 / day. For how many days could you crash this network and still be saving money because crash costs / day are less than the indirect costs / day that would be saved?

Because direct costs are assumed to be developed from normal methods and in a normal amount of time, any reduction in activity time should ________ the direct cost of the activity.

In selecting the best activity to crash you would first select the activity with the

Consider the following table of activities that describes a project network. What is the first activity you would crash?

Compressing activities on a project with a sensitive project network will:

Sometimes very high __________ costs are recognized before a project begins and reducing these costs through shorter project durations becomes a high priority.

A project that has several near-critical or critical paths is said to be

Which of the following is NOT one of the more commonly used options for cutting project costs?

An activity's ________ is calculated by dividing the rise by the run.
