1. When process tasks in a value- stream analysis are classified, inspection of
parts before they are shipped to a customer is often considered
a. value- added because we have to do it to ensure that the customer receives
only good product.
B. non- value-added because it does nothing to change form, fit, or function and
is needed only because of our poor process quality.
C. business- value- added because it does nothing to change form, fit, or function
and is needed only because of our poor process quality, yet random sampling
inspection ensures that the customer receives only good product.
D. business- value- added for processes considered incapable (i.e., out of control
or C < 2) and non- value- added for in- control and capable processes.

2. From the lean viewpoint, design of products or services that do not fully
meet customers’ needs is considered
a. best practice.
B. waste.
C. value- added.
D. just in time.

3. Standardization is an effective strategy to
a. simplify a process by removing as much of the “special cases” as possible.
B. reduce the number of items needed in inventory.
C. reduce the cost of delivery.
D. all the above are true.

4. Process cycle times can be reduced through
a. reducing the need for rework.
B. reducing the movement of material.
C. level loading to reduce batches and waiting.
D. all the above are true.

5. Impact(s) of level loading a process include
a. reduction or elimination of work- in- process inventories.
B. increased flexibility to respond to change in demand.
C. reduction of batches and downstream waiting associated with batches.
D. all the above are true.

6. Setup time can be reduced effectively with a corresponding reduction in
total cycle time for a unit of production by
a. redesign of processes so that tasks that currently require process shutdown
instead can be performed while the process is operational.
B. increasing the batch size to reduce the number of setups.
