SHORT ANSWER
1. Discuss different ways of defining quality and how these differ for goods and services.
2. List the three principles of total quality and why they are important.
3. Summarize the philosophies of Deming, Juran, and Crosby, highlighting the key points on which they

4. The GAP model recognizes five ways to mis-specify and mismanage the creation and delivery of

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

(Monday through Friday for the last 4 weeks). The data, in the order of the last 20 working days, is given
below.

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.

5. Define Statistical Process Control (SPC) and differentiate between common cause and special (or
assignable) cause variation.

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
