WILLAM EDWARD DEMING

He born on October 14, 1900, Dr. William Edward Deming had a profound effect on the
improvement of production in the USA, during World War II. He is well known for his work in
Japanwhere he guided top management about the improvement indesign, quality testing of a
product and sales he was a contributor of significance in making Japan a nation which produces
high quality of innovative products.

Dr Deming propounded 14 principles for the effective of a business. One of the principles he
propounded was that to stop dependence on mass inspection if you want to achieve quality. It is
better to improve the process and ingrain quality in the product at the first place. He also
advocated institute training for the improvements of skill. He died on December 20 in the year
1993.

Key principles

   1. Create constancy of purpose toward improvement of product and service, with the aim to
        become competitive and stay in business, and to provide jobs.
   2. Adopt the new philosophy. We are in a new economic age. Western management must
        awaken to the challenge, must learn their responsibilities, and take on leadership for
        change.
   3. Cease dependence on inspection to achieve quality. Eliminate the need for massive
      inspection by building quality into the product in the first place.
   4. End the practice of awarding business on the basis of price tag. Instead, minimize total
      cost. Move towards a single supplier for any one item, on a long-term relationship of
      loyalty and trust.
   5. Improve constantly and forever the system of production and service, to improve quality
      and productivity, and thus constantly decrease costs.
   6. Institute training on the job.
   7. Institute leadership. The aim of supervision should be to help people and machines and
      gadgets to do a better job. Supervision of management is in need of overhaul, as well as
      supervision of production workers.
   8. Drive out fear, so that everyone may work effectively for the company.
   9. Break down barriers between departments. People in research, design, sales, and
      production must work as a team, to foresee problems of production and in use that may
      be encountered with the product or service.
   10. Eliminate slogans, exhortations, and targets for the work force asking for zero defects
      and new levels of productivity. Such exhortations only create adversarial relationships,
      as the bulk of the causes of low quality and low productivity belong to the system and
      thus lie beyond the power of the work force.
          a. Eliminate work standards (quotas) on the factory floor. Substitute leadership.
          b. Eliminate management by objective. Eliminate management by numbers,
              numerical goals. Substitute leadership.
   11. Remove barriers that rob the hourly worker of his right to pride of workmanship. The
      responsibility of supervisors must be changed from sheer numbers to quality.
      b. Remove barriers that rob people in management and in engineering of their right to
      pride of workmanship. This means, inter alia," abolishment of the annual or merit rating
      and of management by objective.
   12. Institute a vigorous program of education and self-improvement.
   13. Put everybody in the company to work to accomplish the transformation. The
      transformation is everybody's job.
   14. Improve constantly and forever the system of production and service, to improve quality
      and productivity, and thus constantly decrease costs.

Deming philosophy synopsis
          The philosophy of W. Edwards Deming has been summarized as follows:

"Dr. W. Edwards Deming taught that by adopting appropriate principles of management,
organizations can increase quality and simultaneously reduce costs (by reducing waste, rework,
staff attrition and litigation while increasing customer loyalty). The key is to practice continual
improvement and think of manufacturing as a system, not as bits and pieces.”

In the 1970s, Dr. Deming's philosophy was summarized by some of his Japanese proponents
with the following 'a'-versus-'b' comparison:

       (a) When people and organizations focus primarily on quality, defined by the following
       ratio,




       Quality tends to increase and costs fall over time.
       (b) However, when people and organizations focus primarily on costs, costs tend to rise
       and quality declines over time.


DR. JOSEP JURAN (B. 1904)

Dr. Juran was born on December 24, 1904 in Braila, Romania. He moved to the United States
in 1912 at the age of 8. Juran's teaching and consulting career spanned more than seventy
years, known as one of the foremost experts on quality in the world.


A quality professional from the beginning of his career, Juran joined the inspection branch of the
Hawthorne Co. of Western Electric (a Bell manufacturing company) in 1924, after completing his
B.S. in Electrical Engineering. In 1934, he became a quality manager. He worked with the U. S.
government during World War II and afterward became a quality consultant. In 1952, Dr. Juran
was invited to Japan. Dr. Edward Deming helped arrange the meeting that led to this invitation
and his many years of work with Japanese companies.

Juran founded the Juran Center for Quality Improvement at the University of Minnesota and the
Juran Institute. His third book,Juran's Quality Control Handbook, published in 1951, was
translated into Japanese. Other books includeJuran on Planning for Quality(1988),Juran on
Leadership for Quality(1989),Juran on Quality by Design(1992),Quality Planning and
Analysis(1993), andA History of Managing for Quality(1995).Architect of Quality(2004) is his
autobiography.
Selected Jurans Quality Theories


Juran's concepts can be used to establish a traditional quality system, as well as to support
Strategic Quality Management. Among other things, Juran's philosophy includes the Quality
Trilogy and the Quality Planning Roadmap.




Juran's Quality Trilogy.


The Quality Trilogy emphasizes the roles of quality planning, quality control, and quality
improvement. Quality planning's purpose is to provide operators with the ability to produce
goods and services that can meet customers' needs. In the quality planning stage, an
organization must determine who the customers are and what they need, develop the product or
service features that meet customers' needs, develop processes which are able to deliver those
products and services, and transfer the plans to the operating forces. If quality planning is
deficient, then chronic waste occurs.


Quality control is used to prevent things from getting worse. Quality control is the inspection part
of the Quality Trilogy where operators compare actual performance with plans and resolve the
differences. Chronic waste should be considered an opportunity for quality improvement, the
third element of the Trilogy. Quality improvement encompasses improvement of fitness-for-use
and error reduction, seeks a new level of performance that is superior to any previous level, and
is attained by applying breakthrough thinking.


While up-front quality planning is what organizations should be doing, it is normal for
organizations to focus their first quality efforts on quality control. In this aspect of the Quality
Trilogy, activities include inspection to determine percent defective (or first pass yield) and
deviations from quality standards. Activities can then focus on another part of the trilogy, quality
improvement, and make it an integral part of daily work for individuals and teams.

Quality planning must be integrated into every aspect of the organization's work, such as
strategic plans; product, service and process designs; operations; and delivery to the customer.
The Quality Trilogy is depicted below in Figure 2.

JURAN'S QUALITY PLANNING ROAD MAP.

as a checklist for understanding customer requirements, establishing measurements based on
customer needs, optimizing

Quality Planning Roadmap is used for Product and Process Development and is shown in
Figure 3.

Developed, and teams must work on improvement projects. The infrastructure should include a
quality steering team with top management leading the effort, quality should become an integral
part of the strategic plan, and all people should be involved. As people identify areas with
improvement potential, they should team together to improve processes and produce quality
products and services.

Under the "Big Q" concept, all people and departments are responsible for quality. In the old era
under the concept of "little q," the quality department was responsible for quality. Big "Q" allow
workers to regain pride in workmanship by assuming responsibility for quality.


PHILIP CROSSBY (1926–2001)

Philip Bayard Crosby was born in Wheeling, West Virginia, in 1926. After Crosby graduated
from high school, he joined the Navy and became a hospital corpsman. In 1946 Crosby entered
the Ohio College of Podiatric Medicine in Cleveland. After graduation he returned to Wheeling
and practiced podiatry with his father. He was recalled to military service during the Korean
conflict, this time he served as a Marine Medical Corpsman.
In 1952 Crosby went to work for the Crosley Corp. in Richmond, Indiana, as a junior electronic
test technician. He joined the American Society for Quality, where his early concepts concerning
Quality began to form. In 1955, he went to work for Bendix Corp. as a reliability technician and
quality engineer. He investigated defects found by the test people and inspectors.


In 1957 he became a senior quality engineer with Martin Marietta Co. in Orlando, Florida.
During his eight years with Martin Marietta, Crosby developed his "Zero Defects" concepts,
began writing articles for various journals, and started his speaking career.


In 1965 International Telephone and Telegraph (ITT) hired Crosby as vice president in charge of
corporate quality. During his fourteen years with ITT, Crosby worked with many of the world's
largest industrial and service companies, implementing his pragmatic management philosophy,
and found that it worked.


After a number of years in industry, Crosby established the Crosby Quality College in Winter
Park, Florida. He is well known as an author and consultant and has written many articles and
books. He is probably best known for his book Quality is Free(1979) and concepts such as
hisAbsolutes of Quality Management, Zero Defects, Quality Management Maturity Grid, 14
Quality Improvement Steps, Cost of Quality,andCost of Nonconformance. Other books he has
written include Quality Without Tears(1984) and Completeness(1994).


Attention to customer requirements and preventing defects is evident in Crosby's definitions of
quality and "non-quality" as follows: "Quality is conformance to requirements; non-quality is
nonconformance."

CROSBY'S COST OF QUALITY.


In his book Quality Is Free, Crosby makes the point that it costs money to achieve quality, but it
costs more money when quality is not achieved. When an organization designs and builds an
item right the first time (or provides a service without errors), quality is free. It does not cost
anything above what would have already been spent. When an organization has to rework or
scrap an item because of poor quality, it costs more. Crosby discusses Cost of Quality and Cost
of Nonconformance or Cost of Non quality. The intention is spend more money on preventing
defects and less on inspection and rework.

CROSBY'S FOUR ABSOLUTES OF QUALITY.
Crosby espoused his basic theories about quality in four Absolutes of Quality Management as
follows:


   1. Quality means conformance to requirements, not goodness.
   2. The system for causing quality is prevention, not appraisal.
   3. The performance standard must be zero defects, not "that's close enough."
   4. The measurement of quality is the price of nonconformance, not indexes.


To support his Four Absolutes of Quality Management, Crosby developed the Quality
Management Maturity Grid and Fourteen Steps of Quality Improvement. Crosby sees the
Quality Management Maturity Grid as a first step in moving an organization towards quality
management. After a company has located its position on the grid, it implements a quality
improvement system based on Crosby's Fourteen Steps of Quality Improvement Absolutes of
Quality as below:

Step 1. Management Commitment

Step 2. Quality Improvement Teams

Step 3. Quality Measurement

Step 4. Cost of Quality Evaluation

Step 5. Quality Awareness

Step 6. Corrective Action
