QUALITY
“Uncontrolled Variation is the enemy of Quality”.
……..W. Edward Deming
Quality= “Degree or Standard of Excellence”
“You know it when you see it.”

Garvin’s five approaches toward the achievement of quality:
The transcendent approach : Quality is something we can recognize through experiences but not define.
Product-based approach : Quality is tied to inherent product characteristics.
Manufacturing-based approach : Quality is conformance to specification.
Value-based approach : Quality depends on the amount the customer is willing to pay for it.
User-based approach : Quality is fitness for purpose.

QUALITY CONTROL
Dr. Ishikawa`s definition of quality control:
“Quality control is to develop, design, produce and service a quality product which is most economical, most useful and always satisfactory to the consumer. To meet this goal, everyone in the company must participate in and promote quality”.
When problems occur:
1. Look into each area
2. Look into each aspect
Key aspects to check:
• Workers’ skill level
• Working environment
• Equipment
• Machines

1: Create Constancy of purpose toward improvement of product and service, with the aim to become competitive, stay in business.
Purpose:-They must have clarity on the questions; what are we doing, and why are we doing it?
To stay in business requires….
• innovation, research and education
• And constantly improve the design
Deming’s 14 points

2:Adopt the new philosophy:
Why?
• The customer demands and tastes change very fast,
We have to accept new philosophies according to
the market trends and technology revolutions.
Deming’s 14 points

3:Cease dependence on inspection to achieve quality.
Eliminate the need for inspection on a mass basis by
building quality into the product in the first place.
Quality doesn’t come from inspection,
• from improvement of the process. Improve the process
so that defects aren’t produced in the first place.
• This eliminates the need for inspection on a mass
basis.
You can not save money
if you are more worried about
money, than you are about quality.
Deming’s 14 points

4. End lowest tender contracts:
End the practice of awarding business on the basis of
price tag alone.
• Instead, minimise total cost.
• Move toward a single supplier for any one item,
• on a long-term relationship of loyalty and trust.
Deming’s 14 points
Price has no meaning without
measure of the
quality purchased.
11
5. Improve every process:
Improve constantly system of production and service,
to improve quality and productivity, and thus
constantly decrease costs.
• Finding what’s wrong is not improvement.
• Don’t look at outcomes or defects, instead look at
what produces the defects.
Deming’s 14 points
12
6.Institute modern methods of training on the job
• When training, need to understand what the job is
and why it is being done.
• Training must be done on the job, Learning by doing;
• Going into the work and experimenting with work
methods and new ideas, Studying the results, and
striving for perfection.
• New skills are required to keep up with changes in
tools, methods, techniques, product and service design.
Deming’s 14 points

7. Institute leadership:
The aim of management should be to help people to do a
better job.
• Leadership is required not supervision.
• The emphasis of management must be changed from
sheer numbers to quality. Improvement of quality will
automatically improve productivity.
Deming’s 14 points

8. Drive out fear:
Drive out fear so that everyone may work effectively for
the company.
• People are afraid of change, any attempt to make
things better
• Many organisations are run by fear(Like : bonus,
annual ratings)
• To achieve better quality people need to feel
secure
Deming’s 14 points
15
9. Break down barriers:
Break down barriers between departments. People in
research, design, sales, technology and production
must work as a team.
“everybody wins if the system wins”
Deming’s 14 points

10. Eliminate exhortations:
Eliminate the use of slogans and exhortations for the work
force asking for zero defects and new levels of productivity.
• Ensure you substitute work standards and quotas with
effective leadership and effective methods.
• Substitute effective leadership.
Deming’s 14 points

11. Eliminate arbitrary numerical targets:
• Focus on quality rather than quantity of product.
• Remove obstacles from work.
• Substitute aids and helpful leadership for improvement
• The focus is ”not on how many you make, it is on how
well you make them”.
Deming’s 14 points

12. Permit pride of workmanship:
• Remove the obstacles and barriers that deprive workers,
and people in management
• Abolition of the annual merit rating (appraisal of
performance) which creates conflict and competition
• Involve employees, at all levels, in the process of
improvement.
Deming’s 14 points

needs people that are improving with education.
Deming’s 14 points

14. Put everybody in the company to work to accomplish
the transformation. The transformation is everybody’s job.
• Develop a critical mass that will bring about the change; a
critical mass including top management.
• Create a structure in management who spend time in the
work reinforcing and the organisation’s commitment to it’s
customers and to quality.
• Without such a structure no viable long-term benefits will
be achieved.
Deming’s 14 points
