Managing Quality Improvements
ISSUED BY THE
INTERNATIONAL FEDERATION OF ACCOUNTANTS
Foreword
The Council
of the Malaysian Institute of Accountants has approved this Foreword for
publication.
The status of
Statements on International Management Accounting Practice is set out in the
Council’s statement on Approved Management Accounting Statements.
CONTENTS
-
The world economy has changed.
Enterprises in many countries now have the ability to compete globally. In
many sectors, supply exceeds demand. Consumers faced with greater choices have
become more cost- and value-conscious, and are turning to alternative sources
for products and services. Consumers are also demanding improved quality. A
customer lost because of a quality problem may never return but, more
importantly, may take other customers with him or her.
-
In the economic marketplace,
every enterprise is required to define its chosen battlefield and competitive
weapons. Today, quality, cost, innovation and response times to customers are
the competitive weapons of choice for the successful enterprise.
-
In the 1970s and '80s,
traditionally managed businesses that competed with those that mastered total
quality management lost markets that they previously dominated. The successful
companies proved that a better quality product or service, produced and
delivered in a timely manner, can be less, not more, expensive for the
producer.
-
Quality, cost and time frequently
seem to conflict with one another, necessitating trade-offs. These conflicts
exist because traditional cost accounting practices do not always consider the
hidden costs of (poor) quality. For example, an executive in the computer
industry once observed, "If you catch a faulty two cent resistor before you
use it and throw it away, you lose two cents." However, if you don't find it
until it has been soldered into a subassembly, it may cost $ 10 to repair the
part. And if you don't catch it until it is in the computer, the expense may
be well in excess of the manufacturing costs.
-
This is illustrated by the
Quality Lever for a manufacturing company (see Exhibit 1).

-
Traditional accounting practices
measure product costs at the end of the manufacturing process. This process
identifies and captures a limited amount of savings by focusing on scrap,
rework, testing, etc. But if the quality cost opportunities were identified in
the inspection stage before the manufacturing process was finalized, the
savings would be greater.
-
Similarly, the savings would be
even greater if quality and cost opportunities were identified in the product
design phase.
-
Unfortunately, the "fire
fighting" mode of problem solving at the production stage frequently occurs.
Enterprises tend to focus on solving instead of preventing problems. While
they may not have consciously decided to do this, enterprises fall into a
pattern of behavior that favors the "find and fix" approach. Hence, there is a
need for a disciplined quality management that will redirect all efforts to
improving quality in all stages, from the concept of the product or service
through to its delivery to the customer.
-
This Statement provides practical
operating principles and recommended approaches for implementing Total Quality
Management (TQM). It is addressed to management accountants so they can fully
employ their unique skills in the quality management process. It is designed
to:
-
help make the management
accountant a key contributor to the achievement of quality through the use
of Cost of Quality, statistical measures, and other quality management tools
and processes.
-
help in implementing the
initial process of a TQM system and the ongoing continuous improvements in
the enterprise.
-
This Statement assumes an
organization where the decision to implement a TQM process has already been
made.
-
This Statement is, of necessity,
both descriptive and prescriptive. The descriptive parts shape a vision of the
future, build commitment for the change, and define quality concepts and
techniques. The prescriptive part addresses how to lead, plan, and implement
TQM.
-
The concepts, techniques, and the
case study included in the guideline are all structured to be applicable to:
-
businesses that produce a
product or a service;
-
all levels of an enterprise,
from the CEO down;
-
all functions in an enterprise;
and
-
enterprises in all business
sectors.
-
Quality, like excellence, is a
concept that is easy to visualize but exasperatingly difficult to define. It
remains a source of confusion to managers. Quality improvement is unlikely in
such settings. Even when quality has been precisely defined, it has been
focused narrowly on the factory floor or has relied primarily on traditional
methods of quality control. Little attention has been paid to the underlying
sources of superior quality, such as contribution of product design, vendor
management and selection, production and workforce management.
-
Quality remains a difficult
concept because it has undergone a significant evolution since the 1950s.
Quality methods have expanded in ever-widening circles, each incorporating the
elements of the preceding method.
-
During the evolution of quality,
five principal approaches to defining quality have been tried. These are:
-
Transcendent:
Neither mind nor matter. I know it when I see it.
-
Product-based:
Quality of product ingredient or attributes, such as performance, features,
reliability, durability, serviceability and aesthetics.
-
User-based:
Ability to satisfy wants.
-
Manufacturing-based:
Conformance to specification.
-
Value-based:
Quality at an acceptable price.
-
These differing approaches
coexist because of the competing views of quality held by members of the
marketing, engineering and manufacturing departments. Despite the potential
for conflict, an enterprise can benefit from such multiple perspectives.
Reliance on a single definition can cause problems. For example, a company may
discover that its product does not meet customer requirements, even though it
conforms to all the specifications. Conversely, the customer satisfaction
rating may be very high, but at a high cost of rejects, scraps, rework, and
warranty costs.
-
In both cases, managers thought
that they were producing high-quality products. And they were, but according
to only one of the approaches to quality described above. Because each
approach has a blind spot, TQM encourages multiple perspectives on quality,
actively shifting the measures of products more from design to quality.
-
The TQM concept is the most
comprehensive quality concept to date. It is no longer an isolated,
independent function dominated by technical experts. It has entered the
corporate mainstream, becoming an activity as worthy of attention as marketing
or production.
-
TQM, as discussed in this
Statement, integrates the contributions of major quality masters such as
Deming, Juran, Taguchi, Ishikawa and Crosby.
-
The TQM approach starts with
identifying the customers and their requirements.
-
Every function, and every
individual within a function, has a set of customers. Each of these customers
has a set of spoken and/or latent needs or requirements.
-
The focus on the
customer-supplier relationship is crucial to any attempt to improve quality.
This recognizes that everyone in a process is at some stage a customer or
supplier of someone else, either inside or outside the organization.
-
At an enterprise level, TQM
starts with the external customer requirements, identifies the internal
customer-supplier relationship and requirements, and continues with the
external suppliers. In a chain of operations to produce a product or service,
there are many internal customer-supplier links. The ultimate, external
customer is better served if each internal customer is also served to the
fullest-in terms of timeliness, completeness, and accuracy (See Exhibit 2).

-
Understanding and meeting these
customer requirements completely is the premise of TQM. See Exhibit 3 for an
example using a manufacturing company.
-
The implementation of TQM
requires care because the various customer requirements are not always
translated properly. The traditional structure of large organizations and the
complexity of the product/service delivery processes often stand in the way.
-
For example, most companies are
organized, out of necessity, along vertical reporting hierarchies. But the
delivery of a product or a service requires a great deal of cooperation among
horizontal linkages.
-
The horizontal linkages in large
organizations tend to be weak and lead to differences in interpretation and
conflicting priorities. If the product development cycles are long, several
key players may also change or be promoted before completion of the output.
-
Because of these complexities,
TQM needs to be formally articulated and understood across all horizontal and
vertical linkages. Ford utilized this concept to develop the Ford Taurus and
Mercury Sable. To bring these cars to market, a cross-function "Team Taurus"
was organized to strengthen internal linkages and to ensure that quality was
designed into the new cars at every stage.

-
Traditionally, the management of
quality has been seen as the exclusive domain of the quality management staff,
manufacturing and production engineering department personnel, and product
design and engineering department personnel.
-
On the other hand, the modern
concept of TQM is seen as a company-wide function and need that requires many
new players.
-
Most existing quality information
gathering, measurement and reporting systems have been developed and operated
by non-accountants. The problem with these systems is that quality data are
seldom accumulated and reported in a manner that emphasizes quality costs and
clearly indicates the impact of quality on financial performance. Instead,
these cost/benefit relationships are buried in a variety of product cost,
marketing, engineering, and service department accounts.
-
Since management accountants are
trained in analyzing, measuring, and reporting information focused on user
needs, their expertise can be of assistance in the design and operation of
comprehensive quality information gathering, measurement, and reporting
systems.
-
To leverage this advantage,
management accountants should integrate quality cost systems into the existing
management reporting and measurement systems. With full knowledge of cost
concepts and allocation procedures, they can measure and report quality costs
in a manner that will contribute to the solution of quality problems. (The
case study in Appendix 1 to this Statement highlights this further.)
-
These efforts will enhance the
role and responsibility of the management accountant in the enterprise. He or
she can highlight the fact that poor quality can be a significant cost driver.
The absence of good materials, trained labor, well-maintained equipment, and
well-conceived management processes can dramatically increase quality costs.
These include scrap, rework, excess inventories, process and equipment
breakdowns, field service, and product warranty claims.
-
As an example, the material
management function in some organizations is evaluated on a purchase price
variance from standard cost. This encourages the acquisition of materials on a
price basis alone rather than on the merits of design quality and price. If
low-cost materials do not possess the right quality, this accounting process
results in high manufacturing costs. Such costs include scrap, rework,
schedule disruptions, etc., all downstream functions for which the material
management function is not accountable. If not managed, the downstream costs
of this lack of quality could exceed the price savings achieved.
-
The management accountant should
be totally involved in all activities of the enterprise. The following
activities illustrate the role of the involved management accountant.
-
ensure that he or she is well
represented on the main quality control committees and employee involvement
teams;
-
ensure that the company knows
the competitive benchmarks, competitive gaps, customer retention rate, and
the Cost of Quality;
-
help identify areas of greatest
quality opportunities;
-
create a system of quality
measures to monitor ongoing progress against quality goals. The existing
reporting systems may need extensive reworking;
-
ensure that accounting is
involved intimately in vendor rating decisions;
-
ensure that he or she takes
part in selection procedures for new manufacturing equipment by attending
outside trials and viewings;
-
discuss quality control
effectiveness and the value of training courses for quality control
personnel and operators with the human resources department; and
-
continually review scrap and
recovery costs and the basis of their evaluation.
-
In service industries, some
adjustment from the management accountant's role may be required if:
-
services are delivered away
from headquarters, at customer premises, and in direct interface with
customers; and
-
operating personnel (i.e.,
repair technicians) are away from headquarters.
-
The management accountant should
be informed and willing to be an active participant in the TQM process. The
management accountant's training and field of expertise will be of value in
this process but the achievement of quality goals will not be driven, only
aided by the application of such expertise.
-
The overriding lesson to be
learned from the evolution of quality in Japan is that there are no easy
answers. TQM cannot be reduced to a cookbook. Many early converts to the
quality approach implemented quality circles, work teams, and other faddish
techniques that merely copied the Japanese style while missing its substance.
Each enterprise that has implemented TQM has developed its own implementation
plans. TQM does not occur overnight; there are no shortcuts. It took the
Japanese more than 15 years to approach and then surpass the quality levels of
the West.
-
In general, the movement within
an enterprise from traditional management to TQM will take between three to
five years and will be difficult as well as time consuming. Many specific
projects along the way, however, can yield high returns quickly.
-
While there is no one perfect
implementation prescription for TQM, the following phases have been used by
the winners of the U.S. Malcolm Baldrige awards for effectively managing
quality.
Year 1
-
Create CEO/Quality council and
staff
-
Conduct executive quality
training programs
-
Conduct quality audit
-
Prepare gap analysis
-
Develop strategic quality
improvement plans.
Year 2
Year 3
Create CEO/Quality
Council and Staff
-
Most companies seeking to
implement TQM have found the transition impossible to achieve without the
direct involvement of the most senior managers, including the chief
executive/president. Leadership for such a change cannot be delegated. It
requires active, unwavering leadership from the CEO. If it means no more than
a few speeches and a lapel pin, quality will not work. CEOs must lead this
change. Most TQM companies establish an executive-level quality council to
oversee the change process, chaired by the CEO or president and composed of
the top management team. The council develops quality mission and vision
statements, the company's long-range quality strategy, and company-wide
quality goals. To support the council, some TQM companies develop a small
quality staff to coordinate and track the quality improvement process, provide
technical guidance and oversight to improvement teams, develop the content of
quality training, and assist professional trainers. Other TQM companies look
to major segments of the total organization to manage this activity and
provide the required information to the corporate offices.
Conduct Executive
Quality Training Programs
|
43. |
Most TQM companies invest
considerable time and effort raising senior management's awareness of the need
for a systematic focus on quality improvement, creating a common knowledge
base concerning total quality, establishing reasonable expectations, and
avoiding misunderstandings and miscommunications as the change effort
progresses. |
Conduct
Quality Audit
-
The quality audit assesses the
effectiveness of efforts to provide background information to support the
development of a long-term strategic quality improvement plan. It may include
an analysis of the quality improvement initiatives and quality performance
levels of "best-in-class" competitors to identify the company's strengths and
weaknesses versus the competition. It should also identify improvement
opportunities that are likely to provide the greatest return to the company in
both the short and long term.
Prepare
Gap Analysis
-
A gap analysis against the
"best-in-class" competitors tells a company what it lacks to move from one
point to the other or to "leap-frog" the competition to become the new
industry leader. It identifies strengths, weaknesses, and target areas for
improvement, which are then fed back to managers and employees. The purpose of
the gap analysis is to provide a common objective data base from which a
strategic quality improvement plan can be developed.
Develop
Strategic Quality Improvement Plans
-
Next, the quality council sets
priorities for quality improvement by developing a one-year short-term
strategic quality plan and a five-year long-range plan based on the gap
analysis and target criteria. Successful TQM plans need to have the support
and participation of every group in the company including unions, where they
exist.
Conduct
Employee Communication and Training Programs
-
Training is used both to
communicate management's commitment to total quality and to provide employees
with significantly enhanced skills in data analysis and problem solving.
Training should be done from the top down: managers who actively participate
in staff training reinforce the importance the company attaches to quality
improvement.
Establish
Quality Teams
-
Most successful TQM companies use
a wide variety of employee and management teams. In addition to work-unit and
self-managed teams, companies have devised quality management boards to
oversee the continuous improvement effort for their line of business and
quality task forces. These are temporary teams that address cross-functional
quality teams.
-
TQM coordinators should serve as
monitors for quality teams. But if the workforce has been provided with proper
TQM training, then the teams should be able to structure themselves and handle
problems on their own.
-
Unique quality teams, including
representatives from the areas involved and a chairperson from an unrelated
area, should be assembled to handle specific problems. Involving people from
unrelated areas gives everyone a chance to share their experiences on how the
TQM process has worked elsewhere.
-
A target should be established at
the outset of the company's TQM process as to the number of quality teams and
issues that will be dealt with at any one point in time. This will ensure that
resources are not being spread too thin and that issues are being resolved
before new topics are added to the process.
Create
Measurement System and Set Goals
-
Crucial to the success of TQM
implementation is the ability of quality teams to develop a better
understanding of their internal and external customer needs and expectations,
and to develop measures that truly reflect these expectations. Frequently, TQM
companies find that traditional measures are not only inadequate, but
misleading, and must be overhauled or discarded. They adopt high goals that
call for improvements by tenfold or more over the span of a few years. They
also measure their performance against not just the "best-in-class" among
their competitors but the "best-in-class" for a function or business process.
Revise
Compensation, Appraisal and Recognition Systems
-
As TQM companies revise their
measurement systems, they also revise their compensation, appraisal, and
recognition systems to reflect the emphasis on quality.
Launch
External Initiatives with Vendors
-
It is important that quality
management be extended beyond the firm. Some of the most significant benefits
of a quality program come about when the concept is also adopted by the firm's
suppliers. In general, TQM efforts should become part of the entire business
system that extends from raw materials to the final customer.
Review and
Revise
-
Quality progress is constantly
reviewed by quality teams and the entire quality improvement effort should be
reassessed at least annually. There is no finish line in the race for quality.
-
Implementing quality is not easy.
It requires active, unwavering leadership, firm goals, and time from the CEO.
Many quality initiatives fail because top management often has other
priorities. If all an enterprise has is symbolism, nothing happens.
-
All enterprises have general
access to the same equipment, technology, financing, and people. The real
difference lies in how these resources are developed and deployed. In addition
to the general implementation guidelines described earlier, the following
management processes, tools and measures need to be adopted by an enterprise
embarking on the road to quality:
Policy
Deployment
-
Policy Deployment is a system for
planning corporate objectives and the related means for meeting them. The
Japanese quality commentators describe it as the key to the TQM system. This
reflects its primary characteristic: that of providing a measurable link
between a company's strategic vision and plans, and the detailed means by
which each level within the company will move toward achieving its related
objectives. Policy Deployment is thus the method that TQM companies use to
ensure goal congruence throughout the organization.
-
Policy Deployment evolved as the
linking or umbrella TQM system in Japan over the last decade. It followed
years of quality effort that had already resulted in a process-centered
business environment where the use of the Plan-Do-Check-Act cycle and
statistical performance measurement was common at all levels. The
Plan-Do-Check-Act process is:
-
As a result, when Japanese
companies refined their strategic planning processes to improve their
long-term competitive advantage, they had the considerable advantage of
already knowing their business process capability. They were already able to
"manage by fact" on a day-today basis. As a result, Policy Deployment offered
Japanese companies two major business benefits. The first was a method of
developing strategic plans that were not only customer-centered, but
incorporated detailed means and related measures for implementing the plans
over the plan period. The second was a method of focusing each organizational
level on common, vital business objectives and testing the capability of the
business entities to achieve the required performance.
-
Policy Deployment is deliberate,
time consuming and, at times, difficult. It requires organizational discipline
to be sustained in the face of day-today pressures. However, there is a
greatly improved chance for TQM by using Policy Deployment (see Exhibit 4).

Quality
Function Deployment (QFD)
-
QFD is a means of ensuring that
customer requirements are accurately translated into relevant design
requirements throughout each stage of the product development process. This
means that the ends and means are linked at each stage. The process, like
Policy Deployment, is simple but very detailed and disciplined. The rewards of
QFD are well worth the extra up-front effort in planning. Toyota reports that,
with QFD, its design cycle was reduced by one-third and the customer
requirements were better reflected in the end product.
Kaizen
-
This is a Japanese term for
Continuous Improvement in all aspects of a company's operations at every
level. The process is often thought of as a staircase of improvement. As you
move from step to step, you follow an improvement, maintain the improvement,
follow an improvement, maintain an improvement, etc. Each step is a small
upward movement (the vertical part of the step). While the steps are small,
the staircase continues to move you upwards.
Employee
Involvement (EI)
-
There is little chance that a
firm's customers will be excited about its products and services if its
workers are not. EI results in excited and committed workers. EI is more than
simply organizing a few quality control circles or worker teams. Teams are
only part of the picture. The creative energies of all employees must be used
for problem solving and continuous improvement. This means that employees must
be trained in new skills and encouraged to apply them on the job. Eventually,
the number of ideas generated and the percentage of these ideas implemented
become important measures of both individual and team performance.
-
As the EI process is absorbed,
many of the roles, responsibilities, and activities of departments and
individuals begin to overlap. The organization will de-layer and decompress.
Responsibility for judgments, decisions, and problem resolutions will shift
downward to those closest to the point of activity.
Suppliers'
Management
-
A supplier is an extension of a
company's own process. An enterprise's ability to serve its customers and to
create a perception of value depends on the suppliers' ability to serve the
enterprise's needs. Building a quality supplier base requires:
-
reducing the supplier base to
reduce variation and to increase supplier commitment and the efficient use
of a buyer's resources;
-
selecting suppliers not only on
price but on their capability to improve quality, cost, delivery,
flexibility, and their willingness to become world class;
-
forming new and long-term
relationships with suppliers as working partners; and
-
specifying precise customer and
supplier expectations and agreeing to their consistent delivery.
Competitive Benchmarking (CB)
-
Most organizations do not really
know who or what is best in their industry. Consequently, most quality
improvement targets are set internally based upon past performance. This
results in conservative estimates of further expected improvements. CB is the
creative tool that enables enterprises to break free of these self-imposed
limits and focus on the competitors and how to exceed their performance.
-
CB is the continuous process of
measuring an enterprise's products, services, and practices against its
toughest competitors. Benchmarks should include a measure of the results as
well as an analysis and the appropriate measures of the process used to
achieve those results. Common benchmarks used are: cost, staffing, yield,
cycle time, on-time, inventory level, and rework.
-
Of all the benchmarks, the most
important may be customer satisfaction. Quality is only as good as the
customer says it is, not what the numbers on the quality control chart show.
In fact, customer satisfaction shows up as the most important criterion of the
U.S. Malcolm Baldrige Quality Award.
-
CB emerged as a management tool
with Xerox in 1979. Several other corporations such as IBM, General Motors and
Motorola-all Malcolm Baldrige Quality Award winners in the United States-have
since adopted it. It helps facilitate a culture that values continuous
improvement, increases sensitivity to changes in the external environment, and
prioritizes the areas to be worked on first.
-
To make CB easier, several best
practices data bases are being developed. One of these is the Ernst & Young
and the American Quality Foundation data base. This is based upon a study of
500 companies in the automotive, banking, computer, and health care industries
in four countries.
Quality
Training
-
An important development tool is
quality training. All employees must be familiar with the tools for
preventing, detecting, and eliminating non-quality.
-
The education process needs to be
customized for the various audiences: executives, middle managers,
supervisors, and workers. A suggested quality education matrix for these
target audiences is provided in Exhibit 5.
Exhibit 5
Quality Education Matrix

Reward &
Recognition
-
Reward and Recognition are the
best means of illustrating the emphasis on TQM. Recognition can range from
public acknowledgment of team accomplishments to rewards such as mugs,
jackets, or monetary bonuses. Rewards should be group-oriented rather than
individual. For example, "TQM DAY" would involve all employees and would be
used to mark a major milestone in the company's effort to attain Total
Quality. "TQM Improvement Team of the Week" would honor a group effort.
-
A Reward and Recognition
structure based upon quality measures can be a very powerful stimulus to
promote TQM in a company.
Customer
Retention
-
Progressive service companies use
an integrated measure of service quality (i.e., customer retention). This is
the yardstick that all service companies need to measure their quality. In
most industries, boosting customer retention can have the same effect on
profits as cutting costs by 10%. Loyal customers spend more, refer new
clients, and are less costly to do business with.
-
Organizations must make it easy
for customers to respond to both what is right and what is wrong. The response
must address issues key to the quality of product or service delivery.
-
Some customers will complain that
the company's product or service does not meet their expectations. But many
find it too easy to simply go somewhere else the next time. It is these
customers that the firm must address.
-
As well, customers rarely make
the effort to say "yes, you gave me exactly what I wanted." This is fair; they
should not have to. But the feedback system should actively pursue this
information so that the organization knows it is proceeding in the right
direction.
Statistical Methods
-
Organizations should have the
ability to apply statistical concepts and methods if they intend to implement
quality improvement programs. Useful statistical concepts for implementing TQM
are described in Appendix 2 to this Statement.
-
In a manufacturing setting, the
following is a summary of the approach used by Motorola, a winner of the U.S.
Malcolm Baldrige Quality Award, to implement TQM. This approach is similar to
the eleven-point TQM implementation process discussed earlier.
-
The Company was a successful
multinational in the 1960s and 1970s. It had such a stranglehold on the market
that it hardly paid attention when Japanese competitors first entered the
marketplace in the late 1970s. It had grown up to be a bureaucratic company in
which one function battled another and operating people constantly bickered
with corporate staff. Disputes over issues as minor as the color scheme of
products had to be resolved by the CEO. The result was painfully slow product
development, high manufacturing costs, and unhappy customers.
-
The Japanese exploited this
weakness with aggressive pricing and proceeded to gain a sizable market share.
By the early 1980s, the company recognized that it had to evolve rapidly into
a world-class organization if it was to survive.
-
The company began by assessing
its corporate strengths and weaknesses as well as those of its competitors. An
important management step was taken in the early '80s when the company
initiated a format benchmarking process to identify the successful practices
of top competitors.
-
The competitive benchmarking
revealed that, to compete successfully, the company had to be driven by its
customers and competitors. It instituted several changes in organizational
structure, product development processes, and supplier relations. It also set
out on a quest for quality.
-
The quality practices and results
were studied at leading-edge U.S. and Japanese corporations. The study
convinced management that the effort had to appear more lasting and convincing
than mere symbolism. A high-level quality council, staffed by senior
executives, was created for a period of a year to study the quality gap,
competitive practices, and to recommend company-specific quality vision,
goals, and action plans.
-
The quality council recommended
the following:
-
TQM needs to be a strategic
imperative.
-
TQM means meeting market and
customer requirements.
-
The quality responsibility lies
with everyone, with top management exercising strong leadership.
-
The quality journey would take
approximately three years. The implementation steps included: extensive
training, re-engineering of work processes, employee involvement, quality
audits, gap analysis, quality teams, measurement systems, and reward
structure. Some of these were to be extended to the vendors as well.
-
To support the three-year
implementation process, a small quality staff needed to be established. It
would coordinate and track the quality improvement process, provide
technical guidance and oversee the improvement teams, develop the content of
quality training, and assist professional trainers.
-
These recommendations were
accepted. Over the following two years, the company invested considerably in
quality training-particularly in Employee Involvement, Team Building, Problem
Solving, Design of Experiments, Statistical Analysis, Quality Function
Deployment, and Policy Deployment. The training began with the CEO and his
staff and cascaded in groups across the company and its suppliers.
-
The above training and
accompanying work process changes began to transform the company. Within three
years the quality and cost competitive gaps were reduced by more than 50%.
Encouraged by this progress, the company set an even more aggressive goal-to
apply for and win the U.S. National Quality Award in the following three
years. This required further intensive TQM efforts. At the end of the period,
the company had increased its customer satisfaction index by 50%, reduced
costs by an additional 20%, improved product quality, as measured by the
customers, by 50%, and had begun to win back market share from competitors.
These results, and the quality journey that had made them possible, were
recognized by the U.S. Department of Commerce which awarded the company the
National Quality Award.
-
Converting the language of
quality into something that management is familiar with, such as dollars,
gives everyone a common language and also facilitates measuring, tracking and
analyzing. Dr. Juran first proposed the concept in the Quality Control
Handbook published in 1951 and it has been greatly refined since.
-
The Cost of Quality is a measure
of what an organization is spending for its overall quality. It can be viewed
as the difference between the actual cost of making and selling products and
services and the cost if there were no failures of the products and services
during manufacture or use.
-
Unfortunately, the term "Cost of
Quality" can leave a negative impression that reflects the thinking of the
1960s when it was believed that better quality products cost more to produce.
But Cost of Quality can provide a very useful tool to change the way the
enterprise thinks about errors.
-
Examples include:
-
getting management attention by
taking quality out of the abstract and into dollar terms, thereby competing
with other cost and scheduling priorities;
-
changing the way employees
think about errors;
-
identifying and prioritizing
areas for corrective actions;
-
measuring the effect of
corrective actions and changes; and
-
providing new emphasis on doing
the job right the first time, every time.
-
The Cost of Quality has two basic
components:
a.
Cost of conformance, i.e.,
cost of prevention
cost of appraisal
b.
Cost of non-conformance or failures, i.e.,
cost of internal failure
cost of external failure or lost
opportunity.
Leading companies supplement these
Cost of Quality measures with other non-financial measures depending upon the
nature of the enterprise. Examples of additional quality measures are
illustrated in Appendix 3 to this Statement.
|
95. |
Most enterprises accept that poor
quality is costing them a great deal of money, but they are shocked when they
find out how much. In the 1980s, the cost of poor quality was estimated to be
10 to 20% of sales dollars or two to four times the profit for an average
company. |
Cost of
Prevention
-
The cost of prevention is the
cost to ensure that customer requirements are met. It is associated with
maintaining quality systems, such as quality control systems. These are
incurred prior to or during production to prevent defective units of output.
-
This is a necessary cost for
error prevention. By far the best way an enterprise can spend its Cost of
Quality dollars is to invest in preventive actions. Unfortunately, many
companies have neglected this valuable investment because of difficulties in
identifying the downstream returns.
-
Examples of preventive actions
include:
Cost of Appraisal
|
99. |
The cost of appraisal is the
cost to ensure the work processes are producing outputs that meet customer
needs or requirements, such as the inspection of raw materials. Here the
term refers to both internal and external customers. These are incurred
after production, but before sales, to identify defective items.
|
100. Examples include:
-
quality data acquisition and analysis;
-
quality measurement criteria;
-
quality audits;
-
laboratory acceptance testing;
-
field evaluation and testing;
-
inspection and testing;
-
raw materials testing;
-
in-process testing;
and
-
review of test and inspection data.
101.
Unlike preventive actions,
appraisal actions do not reduce the number of errors; they only detect a higher
percentage of errors in output before it is delivered to the customer.
Cost of Internal Failure
102.
These are costs of not meeting
customer requirements, such as the cost of having to do work again (rework).
These are easy to identify because many accounting systems already track them.
They are incurred to fix or dispose of the defective items before they are sold.
103. Unlike the cost of prevention and
appraisal, these costs are not value added and never necessary.
104. Examples include:
-
scrap;
-
rework or repair;
-
trouble shooting;
and
-
re-inspect and re-test.
Cost of External Failure or Lost
Opportunity
105. These costs represent the lost
profits associated with not meeting external customer needs or requirements. If
the external customers become dissatisfied with an enterprise's offerings, they
are likely to return the product, not buy from the firm again and, more
importantly, tell other potential customers about their experience. The cost of
a lost opportunity, therefore, includes lost profits from order cancellations
and market share loss.
106.
Examples include:
-
customer service faults;
-
products or services rejected and returned;
-
products or
services recalled for modificatio;
-
repairs and replacements or added service provided under warranty;
-
admitted repairs beyond warranty;
-
product liability;
and
-
customer losses due to poor quality.
107.
Costing quality in service
industries is similar to costing quality in manufacturing. External failures,
however, are a more important quality cost in service industries. Errors in
service are not amenable to rework. In manufacturing industries, customers can
call and demand warranty repairs on a faulty product. In the service industry,
it does not always work that way. The service failure can result in the
company's losing the customer-even without knowing it.
108.
For example, an airline that is
either tardy or has poor in-flight service may not win the loyalty of frequent
business travelers and thereby will lose market share.
109. Management accountants should be
aware that a service company's profit has more to do with customer defections
than with unit costs, economy of scale, and other factors traditionally tracked
by cost accounting. For example, in some industries, companies can boost profits
by 50% just by retaining 10% more of their customers.
110.
The cost of lost opportunity in a
service industry, therefore, needs to be strengthened to include the
probability
of market damage done by poor service.
111. Another major difference between
service industries and manufacturing is that labor costs take up a far greater
proportion of operating costs. This can lead to several challenges. For example,
time cannot be reworked or reclaimed. In a manufacturing organization, raw
material can be reclaimed. But when the material is people's time it cannot.
This means that, by looking at the percentage of time spent on various
activities, Cost of Quality data may equate a reduction in failure costs with
job losses, and cooperation may diminish.
112. Since prevention and appraisal
costs are a function of managerial discretion, they are referred to as voluntary
costs. Management makes direct decisions about the current funds to be budgeted
for these voluntary costs. In contrast, investments to manage non-conformance or
failure costs may not be directly controllable by management. For example, the
cost of customer dissatisfaction, while not easily measurable, may trigger a
cost for management to contain.
113.
Even though non-conformance costs
may not be directly controllable, they are definitely related to voluntary
costs. When additional resources are allocated for prevention and appraisal
activities, quality improves and non-conformance costs tend to decline.
Conversely, when quality conformance efforts are reduced across the supplier,
manufacturer and distribution chain, non-conformance costs increase.
Accordingly, voluntary costs and failure costs move in the opposite direction.
114. Therefore,
the minimum amount of total quality cost is located at the point where the
marginal voluntary expenditures are equal to the marginal savings on
non-conformance costs (see Exhibit 6).
115. From Exhibit 6, it is clear that
the minimum total quality cost per unit is located at a level of quality
assurance that is less than 100%. At very low levels of assurance, significant
internal and external failure costs outweigh any cost savings that could be
attained by avoiding voluntary costs. In contrast, extremely high levels of
quality assurance result in voluntary cost expenditures that cannot be offset by
non-conformance cost savings.
Exhibit 6
Optional Quality Cost

116. For an organization not steeped in
TQM, the costs of internal failures and lost opportunities will comprise the
biggest part of the total Cost of Quality. As these non-conformance costs are
identified and managed, the relative balance between conformance and
non-conformance costs shifts. In a steady state, both the conformance and
non-conformance costs decline, though as a percentage of total Cost of Quality,
the conformance costs increase as shown in Exhibit 7.

117.
Management accountants require a
clear understanding of TQM methodology. They should also be able to create a
system of quality information measurement and to evaluate exactly what is
required by each organizational unit and by the total enterprise.
118.
The management accountant may need
to extensively rewrite existing product costing and reporting systems. The costs
associated with lost opportunities or loss of market prominence as quality falls
below customer expectations may require more subjective reasoning than normal.
These costs may have to be subjectively estimated before managers have an idea
of their total quality costs.
119.
Most accounting systems don't
reflect all the specific quality cost categories that are required for quality
management purposes. The management accountant, therefore, must:
-
determine which accounts contain valid information for TQM,
-
reorganize and restructure the existing accounting system to provide accurate
quality cost data; and
-
revise the chart of accounts to reflect each quality cost category.
120.
Another shortcoming of most
accounting systems is their failure to associate costs with activities. The
systems do not provide individual managers and employees with the information
they require to make improvements. Therefore, quality teams will not have the
information necessary to focus on the most important quality problems.
121.
The management accountant needs to
relate quality costs to activities to help quality improvement teams focus their
efforts appropriately in order to assure the success of the TQM effort.
122.
The solution lies in applying
techniques from activity-based costing to TQM. Activity-based costing yields
improved information because of its use of an extensive cost driver
identification process to relate activities to products or services.
123.
Cost drivers (such as the number of
different parts used or the effort expended by a product) reflect the
consumption activities of a product or service. Examples of activities include:
Cost drivers allow quality teams to
pinpoint activities which are the result of not doing things the right way.
124. Since no standard format has been
developed for Cost of Quality reporting, the types of items included vary within
and among companies. For example, some Cost of Quality reports include overhead
related to internal failure costs while others do not. These differences make it
difficult to compare the performance of organizational units. If managers are to
be evaluated on the quality cost performance of their units, the management
accountant should ensure that the Cost of Quality reports are standardized.
125. In addition to these challenges,
the management accountant must recognize that the quality cost performance
measures will vary widely depending upon the organization. Nevertheless, he or
she should ensure that the measurement and reporting process meets the following
criteria:
-
directly relates to the requirements of the internal customer using these
measures and reports;
-
uses Cost of Quality measures as well as other non-financial measures;
-
uses measures that vary between locations depending upon quality and business
challenges;
-
uses measures that change over time as the needs change;
-
is
simple and easy to use, implement and monitor;
-
provides fast feedback to users and managers;
-
is
intended to foster improvement rather than just to monitor; and
-
motivates people to achieve quality gains.
126.
Management accountants will need to
be aware that, although Cost of Quality data can be an attention-getter for
senior management, precision measurement may be redundant. Arguments can arise
over the correct classification of costs. If the Cost of Quality runs as high as
20% of revenue, greater precision in calculating cost seems to be of little
value and perhaps very expensive to achieve. Therefore, techniques such as
periodic audits of Cost of Quality may suffice if the accounting system changes
prescribed earlier are prohibitively expensive. The primary benefits of the Cost
of Quality are its initial shock value and its function as a means to measure
improvement over time.
127.
Based upon these challenges, a
proposed summary of the quality cost process is described in Exhibit 8.
128.
Examining the Cost of Quality
allows the enterprise to identify, prioritize and monitor quality improvements.
Other measures and processes (such as statistical analysis, Quality Function
Deployment, Policy Deployment, quality circles and benchmarking) will also be
required.
129. The leadership for a company-wide
quality transition has to start at the top. It cannot be delegated. The
companies that have successfully moved to the quality paradigm established an
executive-level quality council to oversee and propel the change process. The
council must be chaired by the CEO or the president and composed of the top
management team.
130. The management accountant has the
skills required to be a valuable contributor to the executive quality council,
advising on quality opportunity areas and the measures and reports required to
monitor progress.

131.
The journey on this quality path is
difficult. It can take several years to make significant progress. Several
behavioral factors common to large organizations can become inhibitors. For
example, some functions may be identified as contributing to the Cost of
Quality. The managers of these functions may not cooperate. There may also be
debates about what should be considered as opportunities for managing the Cost
of Quality. Finally, change at one step of the production process may cause
unexpected or hidden changes in subsequent processes.
132.
A company that has successfully
implemented TQM can expect improved market share or profits or both. Cost
reductions of 5 to 10%, out of a potential 20% of sales, are not uncommon.
133.
Companies near the end of their
transition to TQM appear very different from when they started. The differences
show up, for example, in the following areas:
-
the organizational structure becomes more efficient and flexible. Internal
communication improves as some non-value-added or "find and fix" functions are
reduced;
-
internal measures of performance are replaced or supplemented by
customer-oriented quality measures. Several new financial and non-financial
measures (such as customer satisfaction) are added;
-
all employees in all departments are introduced to the basic tools and
philosophy of TQM. Decision making becomes more broadly distributed;
-
there are many cross-functional improvement efforts;
-
suppliers become heavily involved and "buy in" to programs related to the
quality quest;
-
key products/services and markets are reorganized;
-
several management processes are institutionalized, such as benchmarking,
continuous improvement, elimination of waste, prevention not detection, JIT,
reduction of variation, statistical thinking, and consistent management
practices.
134.
While many companies can expect a
successful transition, others will falter or achieve only partial benefits. They
fail because they do not recognize that the total journey can take several
years. Over this time there can be changes in the key players or competing
management priorities. This Statement is designed to alleviate some of these
pitfalls.
Case Study
It is
impossible to provide a general model of quality costing for all companies.
Since a
standard format for Cost of Quality reporting has yet to be developed,
management accountants may not be aware of the analytical methodologies. Various
types of analysis, reports and graphs can be developed once the data has been
gathered, surveyed by questionnaires, or estimated by knowledgeable personnel. A
case study in a manufacturing environment is described below to highlight the
analytical methodologies used to identify the areas for quality improvement.
Manufacturing Example
Manufacturing
company X operates in a highly competitive environment and has been experiencing
increasing cost and quality pressures from new Japanese entrants. By Year 1, the
external failure costs as measured by warranty claims, customer dissatisfaction,
and share loss had increased to 60% of the total Cost of Quality.
Realizing
this, the company instituted a corporate-wide quality program, using a
three-year TQM process, to win customers back. This required considerable
investments in voluntary prevention and appraisal costs.
In the first
year, the company increased the voluntary prevention and appraisal costs by
approximately 50%. In the second year, the investment began to pay dividends.
The
management accountant gathered and summarized the quality costs in the following
Cost of Quality report. The purpose of the report was to communicate to
management the magnitude of the Cost of Quality and provide a baseline for
measuring the impact of future improvement activities (see Exhibit 9).

A decrease in
the warranty costs resulted from a decrease in defective products delivered to
customers. The market share, however, did not yet show a gain. This can be
expected when a company first begins to emphasize quality. It takes time for
quality to work its way through to the market share. Increased quality should
show up later as the customers experience it and the company re-establishes
itself.
Year 1 and 2
quality costs were further summarized (see Exhibit 10). This graph showed the
magnitude of the quality costs and compared the current period's costs with the
prior year's. As TQM is fully implemented by company X, total quality costs will
decline. Prevention and appraisal costs, however, will increase in proportion.
Exhibit
10

The quality
cost data provided by the management accountant pointed to the areas that needed
quality improvement. The problem areas were addressed through quality circles
and problem solving groups. Several times, further analysis of the data through
statistical analysis techniques was necessary.
Rework and
reject was the biggest line item in the internal failure costs. The company
found it necessary to break it down by product. One of the most powerful
analytical tools is Pareto Analysis. This technique was used to identify the
products requiring further root cause analysis. Exhibit 11 showed that three
product lines out of fourteen accounted for 70% of the total scrap.
Further root
cause analysis explained that the parts on these three product lines were
scrapped because of the overall sub-system tolerance requirements. With this
information, management investigated the reasons for the low part tolerance
parameters and formulated a plan to correct the situation.

Statistical Tools and Processes
Measures
Traditional
accounting systems do not provide sufficient information to personnel
responsible for observing the production process, charting quality performance,
or identifying special causes of variation.
Management
accountants need to understand the use of statistical tools and processes
measures so that they can actively participate in and contribute to the TQM
process. A sample listing is presented below.
Closed
loop
In a closed
loop process, feedback provides information about the process output. When this
information shows the need for correction, the process output is corrected
automatically. A closed loop can be effective in reducing variability and
centering a process if the process feedback is correctly analyzed and if process
adjustments are appropriate.
Error
The result of
failing to correctly perform an action. Errors result in non-conforming outputs
if left uncorrected.
Error
Reduction
The reduction
of errors, measured in terms of error rate. Improvement efforts should be
directed to reducing errors rather than correcting non-conforming outputs.
Non-random
Variations
A term
referring to variation in a process output, sometimes used in analyzing control
charts. This variation is the result of "special" causes and can often be
improved by the employees (supported by their managers) who use the process
being measured. Usually these variations show up on control charts as points
outside the control limits, or as trends, shifts or periodic changes.
Process
Capability Measurement
A measurement
to determine if a process can produce output that is both centered on the target
and well within the specifications limits. A process is "capable" if it fully
conforms to customer requirements; meets predetermined levels of centering on
the target value and variability within the specifications limits; and is in
control.
Process
Quality Assurance
A system that
verifies that the process is being followed, that the enablers for the process
are in place, and that the process is consistently capable of achieving
specified outputs.
Random
Variation
A term
referring to inevitable variation in a process output, sometimes used in
analyzing control charts. Random variation is usually the result of "common"
causes that can often be improved only by management (in contrast to "special"
causes that the employee using the process may often address). While the causes
may appear to have a small effect, a single cause may substantially influence
the size of the variation.
Six Sigma
Quality
Sigma is a
measure of variation in a product or process. It is a symbol for a statistical
parameter known as standard deviation. In a typical process, X represents the
process average and sigma its standard deviation. Generally, the process width
is defined as X ± 3 sigma. If the specification width was the same, the process
used to be considered in control. But in real terms, such a process would have a
defect rate of 0.27 percent or 2,700 defects per million units. If, however, the
process width is halved and the specification width remained the same, the
latter's boundaries would be at X ± 6 sigma. In such a case, the defect rate
would be only 2 defects per million units. And even if the process average
shifted by 1.5 sigma to one side, the defect rate would only be 3.4 defects per
million units. This is the statistical meaning of ± 6 sigma.
In product
terms, Motorola's goal is for every important parameter to be designed, built,
and brought to ± 6 sigma; that is, the process width would be no more than half
the specification width. In administrative terms, ± 6 sigma is simply
perfection; that is, having a defect rate of no more than 3.4 errors per one
million opportunities for error. Motorola is dedicated to achieving this state
of perfection by 1992.
Standardization
This ensures
the consistent use of a process or procedure across all applicable areas. After
a process improvement has been tested and verified, the improved process must be
standardized to maintain the benefit across the corporation.
Statistical Process Control (SPC)
The
application of statistical techniques for measuring and analyzing the variation
in processes.
Statistical Quality Control (SQC)
The
application of statistical techniques for measuring and improving the quality of
processes. SQC includes SPC, diagnostic tools, sampling plans, and other
statistical techniques.
Statistical Tools
Graphical
and/or numerical methods that assist in the analysis of a process or population
of events. Often the tools use a sampling of the population to make a judgment
and decision about the entire population.
Listed below
are the seven most commonly used statistical tools for analytical problem
solving.
-
Check Sheets;
-
Cause and Effect Diagrams;
-
Histograms;
-
Pareto Diagrams;
-
Control Charts;
-
Scatter Diagrams; and
-
Graphs.
Stratification
The process
of classifying data into two or more sub-groups based on categories or
characteristics. This is a powerful and frequently used tool. When the data are
stratified according to the variables, which are thought to cause variation, the
causes of variation can be detected more easily.
10X
Improvement
(Also known
as "tenfold reduction".) 10X Improvement means reducing the process's error or
non-conforming output rate to 10% of its existing rate. Improvement is measured
by examining ongoing quality in terms of error and non-conforming output rates.
Variability
The
inevitable changes in the measured values of a process output. Changes are due
to random causes (natural or common causes) or non-random causes (special
causes). Variability can be measured. It describes the spread of the measured
output values around the average. Sigma (standard deviation) is an often used
numerical measure of variability. Variation can be visually represented through
the use of graphical techniques.
Variability Reduction
The process
of reducing the spread of values of a process output. To reduce variability, you
separate the random from the non-random variation before you develop corrective
action plans. You then use different corrective actions for the random and
non-random causes.
Additional Quality Measures
Cost of
Quality by itself cannot resolve quality problems. It is only designed to help
management understand the magnitude of the problem, identify opportunities, and
measure progress. It must be accompanied by an effective improvement process to
reduce the errors in an enterprise. An enterprise should supplement the Cost of
Quality measures with additional measures to maintain focus on unique quality
elements. The management accountant must achieve a working knowledge of these
measures to help quantify the Cost of Quality.
Some of these
measures are common to most organizations. Others may be unique to the nature of
an enterprise, i.e., industry, competition, current and desired state of
quality, etc.
An exhaustive
list of quality measures for manufacturing and service industries is impossible
to create. Many of these measures have to be developed specifically for the
industry, company or quality need. A sample listing is presented below.

Installation failures
-
Scrap and rework

Reinspection and retest

Redesign and engineering changes
