Chapter 17
Quality Management
17.1 a. Productivity is a ratio of output to input and measures efficiency.
b. Quality control refers to methods used to ensure product or service quality.
c. Process control refers to methods used to ensure process consistency and
conformance to process specifications.
Learning Objective: 17-1
17.2 From the modern perspective productivity and quality move in the same direction. When
you improve quality you also improve productivity. In the past, the relationship was
thought to be the inverse. People believed that to improve quality they must slow
down processes which would decrease productivity. This is not the case if one
considers that rework and scrap due to poor quality actually decrease productivity.
Learning Objective: 17-1
17.3 Common cause variation is normal and expected. It’s part of the process. Special cause
variation is caused by something outside the normal process.
Learning Objective: 17-1
17.4 Zero variation is a lofty goal but not achievable. Variation will always exist. We can
attempt to minimize variation but cannot eliminate all sources of variation.
Learning Objective: 17-1
17.5 Statisticians help organization define metrics used to measure quality and then help
design data collection and process monitoring systems.
Learning Objective: 17-1
17.6 Students may name Deming, Shewhart, Ishikawa, Taguchi, and others they’ve heard of.
Learning Objective: 17-2
17.7 Deming’s 14 Points (abbreviated)
1. Maintain constancy of purpose.
2. Adopt a new philosophy.
3. Don’t rely on inspection—design quality in.
4. Don’t award contracts just on the basis of price.
5. Continuous improvement.
6. Institute training on the job.
7. Supervision should help people do a better job.
8. Drive out fear and create trust.
9. Break down barriers between departments.
10. Eliminate slogans, exhortations, and targets.

11. Eliminate numerical goals.
12. Remove barriers to pride in work.
13. Continuing education for all.
14. Act to accomplish the transformation.
See www.deming.org for a more detailed complete list.
Learning Objective: 17-2
17.8 a. A car dealership typically surveys their customers and might track the number of
customers who respond that they were satisfied with their service.
b. A bank might track the number of transactions that are error free. They might track
the time required to complete a transaction.
c. The movie theater might track the time required to purchase a ticket or the number of
customer complaints.
Learning Objective: 17-3
17.9 SQC refers to a specific set of tools used to monitor, improve, and control product
quality. Most of the tools rely on statistical techniques. SPC refers to the statistical
tools used to monitor, improve, and control process characteristics.
Learning Objective: 17-3
17.10 Total Quality Management or TQM
Business Process Redesign or BPR
Continuous Quality Improvement or CQI
Six Sigma or 6-sigma uses the DMAIC cycle (define, measure, analyze, improve,
control)
PDCA cycle (plan, do, check, act)
Learning Objective: 17-3
17.11 The improvement process is never-ending because once you eliminate one source of
variation you move to the next source of variation. Two cycles: PDCA (plan, do,
check, act) and DMAIC (define, measure, analyze, improve, control)
Learning Objective: 17-3
17.13 Service blueprints and Service transaction analysis
Learning Objective: 17-3
17.14 Attribute control charts are for nominal data (e.g., proportion conforming) while variable
control charts are for ratio or interval data (e.g., means).
Learning Objective: 17-4
17.15 a. Sampling frequency depends on cost and physical possibility of sampling.
