1. The processes required to ensure that the project will satisfy the needs
for which it was undertaken include all activities of the overall manage-
ment function that determines the quality policy, objectives, and re-
sponsibilities and implements them by means such as quality planning,
quality control, quality assurance, and quality improvement, within the
quality system. This is called:
a. Quality assurance.
b. Quality control.
c. Quality planning.
d. Quality management.

11. The quality manager of a company wishes to analyze the data that is
coming to him in the form of a list of defects that have occurred in the
shipping department. The report comes with defects listed chronologi-
cally as they occurred, the cost of the repair necessary to correct each
defect, the person involved, and a description of the defect. The man-
ager would like to determine which of the defects should be corrected
first according to the frequency of the defect occurring. He should use

spector takes the printed circuit assembly and puts it into a fixture. The
fixture is part of a testing machine that has three digital readouts. The
inspector records the readings on the three digital readouts on his in-
spection report. This is an example of:
a. Attribute inspection.
b. Variable inspection.
c. Sampling inspection.
d. Process control.
19. One of the important advantages of using control charts in managing a
production operation is that the control chart tells you when to take
corrective action on the process being controlled. Another important
result of using control charts is:
a. The control chart identifies the special causes.
b. The control chart tells you when you should not take corrective
action.
c. The control chart shows how much the defects are costing.
d. The control chart shows who is responsible for the defects.
