CHAPTER 14
QUALITY AND ENVIRONMENTAL
COST MANAGEMENT
DISCUSSION QUESTIONS
1. Quality of design is a function of the
product’s specifications, whereas quality of
conformance is a measure of how a product
meets its specifications.
2. All quality costs are incurred because poor
quality may or does exist.
3. The zero-defects approach emphasizes con-
forming to specifications. Upper and lower
limits are set for product variation, and any
unit that falls within those limits is deemed
acceptable (units outside the range are de-
fined as defective). The robust quality
approach emphasizes “fitness for use.”
There is no range within which variation is
acceptable. Thus, any unit not meeting the
target is defective.
4. Under the robust quality approach, any vari-
ation from the ideal entails a loss, a loss
which grows larger as the variation in-
creases. This approach leads to the Taguchi
quality loss function, which is based on the
idea that any variability from the ideal caus-
es hidden quality losses or costs. The
Taguchi quality loss function shows that
costs increase at an increasing rate as vari-
ability increases. This function is symmetric.
5. Prevention costs are incurred to prevent de-
fects in products; appraisal costs are costs
incurred to determine whether products are
conforming to specifications; internal failure
costs are incurred when nonconforming
products are detected prior to shipment; and
external failure costs are incurred because
nonconforming products are delivered to
customers.
6. External failure costs can be more devastat-
ing because of warranty costs, recall costs,
lawsuits, and damage to the reputation of a
company, all of which may greatly exceed
the costs of rework or scrap incurred from
internal failure costs.
7. Agree. It is poor quality, not good quality,
that is costly. All quality costs exist because
poor quality may or does exist.
8. Interim quality standards are used to
measure a firm’s progress toward better
quality within a given period.
9. Interim quality reports are used to measure
quality improvement with respect to a cur-
rent-period standard; multiple-period reports
are used to measure quality improvement
with respect to a base period; and long-
range reports are used to measure progress
toward achieving the goal of zero defects.
10. Both monetary and nonmonetary incentives
can be used. For example, employees can be
given a bonus that is equal to a fixed
percentage of the savings from a suggestion
that improved a product’s quality (referred to
as gainsharing). Additionally, nonmonetary
awards of excellence can be used to
recognize those employees who make
outstanding quality contributions. Gainsharing
pro–vides cash incentives for a company’s
entire workforce that are keyed to quality or
productivity gains.
11. Firms should spend about 2.5 percent of
sales on quality costs. The potential savings
from quality improvement is $31 million [$36
million (0.18 × $200 million) – $5 million
(0.025 × $200 million)].
12. It is possible to improve quality and lower
costs by changing the relative distribution of
quality costs among the four categories. The
optimal mix needs to be identified.
13. A quality cost report shows the amount of
cost for each category as well as the relative
cost of each category. This report requires
managers to identify the costs that should
appear in the report, to identify the current
quality performance level, and to begin
thinking about the level of quality perfor-
mance that should be achieved.
14. Two major reasons: (1) they have the exper-
tise and training, and (2) they have the
objectivity.
