1 Define quality, describe the four types of
quality costs, and discuss the approaches used for quality cost measurement
2 Prepare a quality cost report, and explain
its use
3 Explain why quality cost information is
needed and how it is used
4 Describe and prepare three different
types of quality performance reports
Trang 3CHAPTER 14 OBJECTIVES
5 Discuss how environmental costs can be
measured, reported, and reduced
6 Show how environmental costs can be
assigned to products and processes
Trang 4COSTS OF QUALITY
• A quality product or service is one that meets or
exceeds customer expectations
• Quality of conformance measure of how a product meets its specifications
• Defective product is one that does not conform to
Trang 5COSTS OF QUALITY
• Costs of quality are the costs that exist because
poor quality may or does exist
• Control activities are performed by an
organization to prevent or detect poor quality
• Failure activities are performed by an
organization or its customers in response to poor
quality
• Failure costs are the costs incurred by an
organization because failure activities are
performed
Trang 6COSTS OF QUALITY
• The definitions of quality-related activities
imply four categories of quality costs
1 Prevention costs
2 Appraisal costs
3 Internal failure costs
4 External failure costs
Trang 7COSTS OF QUALITY
• Prevention costs: incurred to prevent
poor quality
• Appraisal costs: incurred to determine
whether products and services are
conforming to their requirements or
customer needs
Trang 8COSTS OF QUALITY
• Internal failure costs: incurred because
products and services do not conform to
specifications or customer needs
• External failure costs: incurred because
products and services fail to conform to
requirements or satisfy customer needs
after being delivered to customers

Quality Cost Measurement
• Observable quality costs: available from an
organization’s accounting records
• Hidden quality costs: opportunity costs
resulting from poor quality
• Three methods of estimating hidden quality costs
1 The multiplier method
2 The market research method
3 The taguchi quality loss function
Trang 11COSTS OF QUALITY
• The multiplier method: assumes that the
total failure cost is simply some multiple of
measured failure costs
Total external failure cost = k(Measured external
failure costs)
• The market research method: used to
assess the effect of poor quality on sales and
market share
• Used to project future profit
losses attributable to poor quality
Trang 12COSTS OF QUALITY
• The taguchi quality loss function: assumes
that any variation from the target value of a
quality characteristic causes hidden quality costs
L(y) = k(y-T) 2
where
K= A proportionally constant dependent upon the
organization’s external failure cost structure
Y = Actual value of quality characteristic
T = Target value of quality characteristic

Trang 15REPORTING QUALITY COSTS
• The first and simplest step in creating a quality
cost reporting system is assessing current
actual quality costs
• A detailed listing of actual quality costs by
category can provide two important insights
• Reveals the magnitude of the quality costs in
each category, allowing managers to assess their
financial impact
• Shows the distribution of quality costs by
category, allowing managers to assess the
relative importance of each category
Trang 16REPORTING QUALITY COSTS
Optimal Distribution of Quality Costs:
Zero-Defects with Robust Quality View
• Take direct attack on failure costs in an attempt to
drive them to zero
• Invest in the “right” prevention activities to bring
about improvement
• Reduce appraisal costs according to results
achieved
• Continuously evaluate and redirect prevention
efforts to gain further improvement

Role of Activity-Based Cost
Management
• Activity-based costing (ABC) can be used to
calculate the quality costs per unit of a firm’s
products
• Classifies activities as value added and
non-value-added
• Keeps only those activities that add value
• Applies to quality-related activities
Trang 20QUALITY COST INFORMATION
AND DECISION MAKING
• Reporting quality costs improves
managerial planning, control, and decision
Trang 21QUALITY COST INFORMATION
AND DECISION MAKING
Certifying Quality Through ISO 9000
• Companies assess the quality of its supplies
through ISO 9000 international quality standards
• Standards are applied to the way in which a
company ensures quality
• For example, testing products, training employees,
keeping records, and fixing defects
Trang 22CONTROLLING QUALITY COSTS
Choosing the Quality Standard
• The total quality approach
• Total quality management standard that will be used
is referred to as the robust zero-defects standard
• Total quality control implies the ultimate elimination
of failure costs
• Quantifying the quality standard
• Quality can be measured by its costs
• As the costs of quality decrease, higher quality
results
Trang 23CONTROLLING QUALITY COSTS
Types of Quality Performance Reports
• Quality performance reports measure the progress
realized by an organization’s quality improvement
program
• Three types of progress measured and reported
• Progress with respect to a current-period standard or
goal (an interim standard report)
• The progress trend since the inception of the quality
improvement program (a multiple-period trend report)
• Progress with respect to the long-range standard or
goal (a long-range report)
Trang 24CONTROLLING QUALITY COSTS
Interim Standard Report
• Compares the actual quality costs for the period
with the budgeted costs
• Measures the progress achieved within the period
relative to the planned level of progress for that
period
Trang 25CONTROLLING QUALITY COSTS
Multiple-Period Trend Report
• By plotting quality costs as a percentage of sales
against time, the overall trend in the quality
program can be assessed
Long-Range Report
• Compares the current actual costs with the costs
that would be allowed if the zero-defects standard
were being met
• A variation of the value- and non-value-added cost
report

Incentives for Quality Improvement
• Nonmonetary incentives
• Monetary incentives
Trang 30CONTROLLING QUALITY COSTS
Nonmonetary Incentives
• Participation helps employees internalize quality
improvement goals as their own
• One approach is the use of error cause
identification forms
• Program in which employees describe problems
that interfere with their ability to do the job
right the first time
Trang 31CONTROLLING QUALITY COSTS
Monetary Incentives
• Gainsharing provides cash incentives for a
company’s entire workforce that are keyed to
quality or productivity gains
• Gainsharing provides an incentive by offering a
bonus to the employees equal to a percentage of
the cost savings

The Ecoefficiency Paradigm
• Ecoefficiency: ability to produce competitively
priced goods and services that satisfy customer
needs while simultaneously reducing negative
environmental impacts, resource consumption, and
costs
• Sustainable development: development that
meets the needs of the present without
compromising the ability of future generations to
meet their own needs

Trang 34DEFINING, MEASURING, AND CONTROLLING ENVIRONMENTAL COSTS
Environmental Costs
• Costs that are incurred because poor
environmental quality exists or may exist
• Four categories
1 Environmental prevention costs
2 Environmental detection costs
3 Environmental internal failure costs
4 Environmental external failure costs

Environmental Cost Report
• Reporting environmental
• Costs by category reveals two important outcomes
• The impact of environmental costs on firm
profitability
• The relative amounts expended in each category

Trang 38DEFINING, MEASURING, AND CONTROLLING ENVIRONMENTAL COSTS
Environmental Cost Reduction
• Investing more in prevention and detection
activities reduces environmental failure costs
• Zero damage is the lowest cost point for
environmental costs

An Environmental Financial Report
• Ecoefficiency suggests a possible modification to
environmental cost reporting
• Specifically, in addition to reporting environmental
costs, report environmental benefits
• Additional revenues
• Current savings
• Cost avoidance (ongoing savings)
Trang 40EXHIBIT 14.12—ENVIRONMENTAL
FINANCIAL STATEMENT
Trang 41ENVIRONMENTAL COSTING
Environmental Product Costs
• Full environmental costing: assignment of all
environmental costs, both private and societal, to
products
• Full private costing: assignment of only private
costs to individual products
Trang 42• Each environmental activity is assigned costs,
activity rates are computed, and the rates are then
used to assign environmental costs to products
based on usage of the activity
• By assigning environmental cost to products,
management can classify products according to their degree of “dirtiness”
