SHORT ANSWER

these differ for goods and services.
2. List the three principles of
total quality and why they are important.
3.

points on which they agree and on which they differ.
4. The
GAP model recognizes five ways to mis-specify and mismanage the creation and
delivery of high levels of quality. Describe each of the five problem areas

PROBLEM
1. Each day, a golf resort handles 700 golfers. Each
guest encounters 22 "moments of truth" during a typical day. The
resort is open seven days a week. If they receive 12 complaints per week,
what is the epmo measure?
2. Over
the last year, 1,100 oral medications were administered at a health clinic.
Quality is measured by the proper amount of dosage and the use of the correct
drug. In three (3) instances, the incorrect amount was given, and in two (2)
instances, the wrong drug was selected. What is the epmo metric?
3. An
airline performed 4000 preflight inspections during one month. Each inspection
checks 50 items. What is the maximum number of defects that could occur during
a year if the process is operating at a six sigma level?
4. The employees in an insurance
company’s mailroom are responsible for sorting and delivering the incoming U.S.
mail to the correct departments. These employees have been receiving
numerous complaints that mail is being delivering to the wrong
departments. To better understand these complaints, the mailroom
employees recorded the number of these complaints they received each day for
the last 20 working days (Monday through Friday for the last 4 weeks).
The data, in the order of the last 20 working days, is given below.
TRUE/FALSE
1. Quality control focuses on the design of a good or
service to ensure meeting customer expectations.
2. It
generally costs more to correct an error or defect at the design stage than
after it has reached the customer.
3. A key
element of a control system is the ability to measure performance and compare
it to a performance standard.
4.
“Quality at the source" focuses on supplier quality at the beginning of a
value chain.
5. In
manufacturing, quality control is generally applied at the receiving stage from
suppliers, during various production processes, and at the finished goods
stage.
MULTIPLE CHOICE
1. Common cause variation is
2. Which
of the following is not a component of a control system?
3. In the
1:10:100 Rule, which of the following would be correct?
4. Quality at the source means that
quality is controlled by
5.

SHORT ANSWER
1. Define and give an example of the three components
of any control system.
2.
Explain and give the significance of the 1:10:100 Rule.
3. Define
"quality at the source."
4.
Discuss the three basic quality control practices used in manufacturing.
5. Define
Statistical Process Control (SPC) and differentiate between common cause and
special (or assignable) cause variation.
PROBLEM
1. A production process is sampled 24 times with a
sample size of 6 yields an overall mean of 25.2 and an average range of 0.8.
Determine the control limits for the x-bar and R charts.
2.
Fifteen samples of size 5 have been taken from a production process. The sum of
the sample averages was found to be 92.54 cm while the sum of the ranges was
115.36. Find the values of the center lines for the x-bar and R charts.
3. Over
several days, 25 samples of 100 items each were tested for electrical
resistance. A total of 60 items failed. Determine and the control limits
for a p chart.
4. An
airline found that on average, 0.62% of the luggage they received from
passengers at LAX (Los Angeles Airport) is lost or damaged. On a typical
day, 1000 pieces of luggage pass through this airport. The upper control limits
for a p chart for monitoring the daily fraction nonconforming?
5. Flaws
are counted on a standard steel plate (sheet). Each sheet has the exact same
dimensions. Ten sheets are selected at random and the number of flaws per sheet
is as follows.
