under 2.5 percent of sales.

Consider a three sequentially stepped process named as Process A, Process B and Process C. Input comes into Process A. Output form A goes into Process B. Output from B goes into Process C. Output of C is the final output. Suppose that it takes 2 minutes per unit in Process A, 3 minutes per unit in Process B and 1 minute per unit in Process C. What will be maximum steady state output from this system? Multiple Choice • 30 per hour • 60 per hour • 20 per hour • 10 per hour • cannot tell since it depends on the input rate.

One of the assumptions made using CPM is that project activities can be identified with clear beginning and ending points. Here are the data for a time-cost CPM scheduling model analysis. The time is in days and the costs include both direct and indirect costs.

Multiple Choice • Total time is 13 days, total cost is $1,200. • Total time is 12 days, total cost is $1,700. • Total time is 11 days, total cost is $1,600. • Total time is 10 days, total cost is $1,750. • Total time is 9 days, total cost is $1,700.

A project may be defined as a series of related jobs directed toward some major output and requiring a significant period of time to perform.

When reducing the planned duration of a project using the time-cost CPM model, we select the activity to crash by determining the cost of each alternative and selecting the one whose cost is the greatest.

A series of projects that are organized in such a way that each project utilizes people from different functional areas is using which of the following organizational structures?

Using CPM, what is the latest finish time for the last activity in this project (i.e., the total time to complete the project)? Multiple Choice • 10 days • 7 days • 8 days • 12 days • 9 days

Upper-level management must decide between pure, functional, and matrix structures as ways to organize projects. In a CPM analysis, if you subtract the late finish from the early finish, the result is the activity's slack time.

You are managing a project and need to cut the cost of the project. You decide to transfer workers to another job to cut the project's costs. Costs associated with transferring the workers are an example of project indirect costs. A simple project listing of five activities and their respective time estimates are presented here:

Using CPM, which activities make up the critical path? Multiple Choice • A, C, D, E • A, B, D, E • A, C, B, D, E • A, D, E • None of these
