Despite there are eight gurus in assessing total quality
management , but there are differences in their opinions.

3. Three groups of gurus

4. W. Edwards Deming
• Born:- October 14, 1990.
• Died:- December 20, 1993
• Dr. W. Edwards Deming is
known as the father of the
Japanese post-war industrial
revival and was regarded by many
as the leading quality guru in the
United States.
• His expertise was used during
World War II to assist the United
States in its effort to improve the
quality of war materials

5. - He got his PHD in the states in physics and math's
- Get his first employment chance in an electricity
company in Chicago
- He taught physics , mathematics , statistics and quality
in Japan .
* Deming is best known for his management philosophy ,
establishing quality , productivity and competitive
position .

6. • Deming focus on 5 ideas :
1. Statistical process controlling (SPC)
2. Deming philosophy
3. Deming 14 points
4. Deming Cycle (for continuous improvements)
5. Seven deadly diseases of quality

7. 1. Statistical process controlling: It’s a process which aims
at achieving good quality during manufacture through
prevention rather than detection .
It is concerned with controlling the process (machine)
which make the product through inspecting the machine
rather than the product itself.
• For example why the salesman can’t sell the same
amount every month ?
• SPC will answer this question by discovering and
analyzing these items :-

8. I. Common causes : which inherent to the process as
Machine fails
II. Special causes : Not inherent to the process and should
be defined such as poor performance
III. Natural Variation: producing certain amount of defects
IV. Significantly different variation: Discovering exactly
where it is by management.
Note. Deming said :
*80% depends on management
*20% depends on employee

9. 2. Deming Philosophy : The quality and the productivity
increases when the process fluctuation Decreases

10. 3. Deming 14 points:
• Create constancy of purpose for improving products and
services.
• Adopt the new philosophy.
• Cease dependence on inspection to achieve quality.
• End the practice of awarding business on price alone;
instead, minimize total cost by working with a single
supplier.
• Improve constantly and forever every process for
planning, production and service.
• Institute training on the job.

11. • Adopt and institute leadership.
• Drive out fear.
• Break down barriers between staff areas.
• Eliminate slogans, exhortations and targets for the
workforce.
• Eliminate numerical quotas for the workforce and
numerical goals for management.
• Remove barriers that rob people of pride of
workmanship, and eliminate the annual rating or merit
system.
• Institute a vigorous program of education and self-
improvement for everyone.
• Put everybody in the company to work accomplishing
the transformation.

12. 4. Deming's cycle

13. 5. Deming's Seven Deadly Diseases
• Lack of constancy of purpose to plan product and service that
will have a market and keep the company in business, and
provide jobs.
• Emphasis on short-term profits: short-term thinking (just the
opposite from constancy of purpose to stay in business), fed by
fear of unfriendly takeover, and by push from bankers and
owners for dividends.
• Evaluation of performance, merit rating, or annual review.
• Mobility of management; job hopping.
• Management by use only of visible figures, with little or no
consideration of figures that are unknown or unknowable.
• Excessive medical costs.
• Excessive costs of liability, swelled by lawyers that work on
contingency fees.

14. Joseph M. Juran
• Born:- December 20, 1904
• Died:- February 28, 2008
• American
• Joseph Juran is an internationally
acclaimed quality guru, similar to
Edwards Deming, strongly
influencing Japanese manufacturing
practices.
• Joseph Juran’s belief that “quality
does not happen by accident” gave
rise to the quality trilogy.

15. Juran Ideas are :
1. Quality definition
2. Breakthrough concept
3. Internal customer
4. Quality Trilogy
5. Pareto analysis
6. Cost of quality
7. Quality council

16. 1. Quality definition : ( Fitness of purpose)
The statement is not that much easy , as it requires asking
many questions like :
• What is the real purpose ?
• Are customer internal or external users ?
• Who are the possible customers ?

17. 2. Breakthrough concept : sequences of process
improvements , which take two journeys
• journey from symptom to cause
• journey from cause to remedy
3. Internal customers : quality is associated with customer
satisfaction and dissatisfaction
• Satisfaction : occurs when the product has superior
performance and features
• Dissatisfaction : when we have defects and deficiencies

18. Customer satisfaction has two dimensions:
• Internal : Building the product and the service correctly
• External : matching customer requirements and meet
their expectations
4. Quality council : A group of experts who are
responsible for supervising in the application of quality
*Juran Big (Q) : quality doesn’t the concern of the
production or the total quality within the organization ,
but it extends to link between organization departments,
operations and services .

19. 5. Juran quality cost :
• Appraisal Costs: Costs of activities designed to ensure
quality or uncover defects (inspection)
• Prevention Costs :All TQ training, TQ planning to prevent
defects from occurring
• Failure Costs - costs incurred by defective parts/products
or faulty services.
• Internal Failure Costs : Costs incurred to fix problems
that are detected before the product/service is delivered to
the customer.
• External Failure Costs : All costs incurred to fix
problems that are detected after the product/service is
delivered to the customer.

20. • Juran three role models : He assumed that every
process has an internal customer and supplier which
linked to each other through a process to reach the
optimum quality .
6. Juran Pareto analysis : A universal problem solving
methodology in which we list the key problems into a
table and ranking them from the highest to the lowest
and trying to solve the deficiencies

21. 7. Quality Trilogy :
Quality planning : *determine the organization internal and
external customers * determine customer needs ,
requirements and expectations * design the product to
achieve customer satisfaction * prepare a design to
achieve a good quality
Quality controlling : *determine variation and make
decisions * measure performance and results * compare
the results with the stated objectives .
Quality improvements : * define quality goals * train the
workers * develop a problem solving statement

22. Philip B. Crosby
* Known as The Fun Uncle of the
Quality Revolution
• Born:- June 18, 1926
• Died:- August 18, 2001
• American
• Where Philip Crosby excellence was
in finding a terminology for quality
that mere mortals could understand.
• He popularized the idea of the "cost of
poor quality", that is, figuring out how
much it really costs to do things badly.

23. • Mr. Crosby defined quality as a conformity to certain
specifications.
Crosby four absolutes are :
1. The definition of quality is conformance to requirements: It is not
appropriate to say good or bad quality as quality cant be measured
but conformance can be.
2. The system of the quality is prevention : Make a prevention
strategy and it should be supported by SPC in order to understand
the process and discover the default before occurring .
3. The performance is zero defects: Make the requirement right from
the first time , and make the quality accepted by a number of
standard items .
4. The measurements of quality is the price of Nonconformance :
Because cost quality is the prime motivation for management .

24. CROSBY quality costs :
• Price of NON conformance :All the costs involved in
not getting the product or a service right .
• Price of conformance : Costs for doing things right .

25. Crosby has 14 points like Deming , like :
- Management commitment
- Building awareness
- Educating employees
- Quality councils
And others but the main difference between Deming and
Crosby is that :
**Deming focus on quality management .
**Crosby focus on action plan and implementation process .

26. Armand Vallin Feigenbaum
• Born:- April 6, 1922
• Died:- November 13, 2014
• He was an American quality
control expert and
businessman.
• Feigenbaum concept's of Total
Quality Control , known today
as total quality management ,
combines management methods
and economic theory with
organizational principles.

27. • He does not get the great attention that the others
(Deming, Juran, Ishikawa, etc.) get.
• Feigenbaum believed that quality was a way of operating
or a way of life, thus the term "Total Quality."
• Believes that quality has become the single most important
force leading to organizational success and growth.
• Feigenbaum defined total Quality control as an effective
system for integrating the quality development, quality
maintenance, and quality improvement efforts of the
various groups in an organization so as to enable
production and service at the most economical levels which
allow full customer satisfaction.

28. • Armand is also know for his concept of the “hidden plant”
the idea that so much extra work is performed in correcting
mistakes that there is effectively a hidden plant within any
factory.
• Accountability for quality: Because quality is everybody's
job, it may become nobody's job—the idea that quality
must be actively managed and have visibility at the highest
levels of management.

29. Feigenbaum believes that there are three elements
to quality:
• Quality Leadership the management in a company must
always be striving for quality. They must put items in place
that allow them to measure quality, control quality and
improve quality. There must be constant feedback and
oversight of the organization to assure that quality
continues.
• Modern Quality Technology the quality function cannot
achieve quality without the help of others. Everyone must
be trained and led to quality.
• Organizational Commitment everyone in the
organization must believe in quality.

30. David A. Garvin
David A. Garvin is the
Professor of Business
Administration at the
Harvard Business School.
"If quality is to be managed, it
must be understood first."

31. • He studied one industry which was active in both
the United States and Japan -- the room air
conditioning industry -- analyzing the products to
determine which plants in which country were
turning out the highest quality. Then he analyzed
every step of the manufacturing process, to find
the differences that made the difference.
• His findings were often surprising. Some things that
everyone thought guaranteed higher quality (such
as exhaustive testing) did not, while some things
rarely mentioned in the literature (such as the way
the factory dealt with layoffs and seniority, and the
length of production runs) made a big difference.

32. The eight dimensions of quality
• Performance: Main operating characteristics such as
power, sound, speed etc.
• Features: The extras that supplement the main
characteristics
• Reliability: How often it breaks down
• Conformance: How close it is to the design
specification or service to the customers experience.
• Durability: Length of life, toughness in use, service
frequency etc.
• Serviceability: Ease, cost and friendliness of service.
• Aesthetics: Appearance and impression.
• Perceived quality: The feel, finish and manner in
which the customer is dealt with.

33. Kaoru Ishikawa
• Born:- July 13, 1915
• Died:- April 16, 1989
• Kaoru Ishikawa was a Japanese
professor and influential quality
management innovator best
known in north America for the
Ishikawa or cause and effect
diagram (also known as
fishbone diagram) that are
used in the analysis of
industrial process.

34. Quality Contributions
• User Friendly Quality Control
• Fishbone Cause and Effect Diagram -
Ishikawa diagram
• Implementation of Quality Circles
• Emphasized the 'Internal Customer'
• Shared Vision

35. Quality Contributions
he was known for the use of the “seven basic tools of quality”:
• Pareto analysis: which are the big problems?
• Cause and effect diagrams: what causes the problems?
• Stratification: how is the data made up?
• Check sheets: how often it occurs or is done?
• Histograms: what do overall variations look like?
• Scatter charts: what are the relationships between factors?
• Process control charts: which variations to control and how?

36. Ishikawa diagram
The Ishikawa diagram (or fishbone diagram or also cause-
and-effect diagram) are diagrams, that shows the causes
of a certain event. A common use of the Ishikawa diagram
is in product design. Also it reveals key relationships
among various variables.

38. Categories of causes
• The 6 M's
– Machine, Method, Materials, Maintenance, Man and
Mother Nature (Environment) (recommended for the
manufacturing industry.
• The 8 P's
– Price, Promotion, People, Processes, Place/Plant, Policies,
Procedures, and Product (or Service) (recommended for
the administration and service industries).
• The 4 S's
– Surroundings, Suppliers, Systems, Skills (recommended for
the service industry(

39. Shigeo Shingo
• Born:- 1909
• Died:- 1990
• Shigeo Shingo, born in Saga City,
Japan.
• He was a Japanese industrial
engineer who distinguished
himself as one of the world’s
leading experts on manufacturing
practices and The Toyota
Production System.
• Shingo is known far more in the
West than in Japan.

40. Shigeo Shingo is strongly associated with Just-in-
Time manufacturing, and was the inventor of :
1) The single minute exchange of die (SMED)
system, in which set up times are reduced
from hours to minutes, and
2) The Poka-Yoke (mistake proofing) system. In
Poka Yoke, defects are examined, the
production system stopped and immediate
feedback given so that the root causes of the
problem may be identified and prevented
from occurring again.

41. He distinguished between “errors”, which are inevitable,
and “defects”, which result when an error reaches a
customer, and the aim of Poka-Yoke is to stop errors
becoming defects. Defects arise because errors are
made and there is a cause and effect relationship
between the two.

42. Poke-yoke
Zero quality control is the ideal production
system and this requires both Poka-Yoke and source
inspections.

43. Genichi Taguchi
• Born:- January 1, 1924
• Died:- June 2, 2012
• Genichi Taguchi was an engineer and
statistician.
• Taguchi developed a methodology for
applying statistics to improve the
quality of manufactured goods.
• Taguchi methods have been
controversial among some
conventional Western statisticians,
but others have accepted many of the
concepts introduced by him as valid
extensions to the body of knowledge.

44. Taguchi methodology
“Taguchi methodology” is fundamentally a prototyping
method that enables the designer to identify the
optimal settings to produce a robust product that can
survive manufacturing time after time, piece after
piece, and provide what the customer wants. Today,
companies see a close link between Taguchi methods,
which can be viewed along a continuum, and quality
function deployment (QFD).

45. Taguchi contributions:
Taguchi has made a very influential contribution to
industrial statistics. The key elements of his quality
philosophy are:
• Taguchi loss function: used to measure financial loss
to society resulting from poor quality.
• The philosophy of off-line quality control: designing
products and processes so that they are insensitive
to parameters outside the design engineer's control.
• Innovations in the statistical design of experiments:
notably the use of an outer array for factors that are
uncontrollable in real life, but are systematically
varied in the experiment

46. Off-line quality control
Taguchi realized that the best opportunity to eliminate
variation is during the design of a product and its
manufacturing process and it consists of 3 stages:
• System design
• Parameter design
• Tolerance design

47. • System design:- This is design at the conceptual level,
involving creativity and innovation.
• Parameter design:- Once the concept is established,
the nominal values of the various dimensions and
design parameters need to be set. Taguchi's radical
insight was that the exact choice of values required is
under-specified by the performance requirements of
the system. This allows the parameters to be chosen
so as to minimize the effects on performance arising
from variation in manufacture, environment and
cumulative damage. This is sometimes called
robustification.
• Tolerance design:- With a successfully completed
parameter design, and an understanding of the effect
that the various parameters have on performance,
resources can be focused on reducing and controlling
variation in the critical few dimensions

48. That’s all.
