Deming
A professor of statistics in 1940s.
Went to Japan after WWII to assist Japanese in improving quality
and productivity.
Japanese established Deming prize for quality.
Deming was unknown in his home country until 80s
He developed a famous list of 14 points he believed were key for
quality in organizations.
His message was; System is the cause for inefficiency and poor
quality not employees. It is management’s responsibility to
improve the system.
The essence of his 14 points are; Constancy of purpose,
continuous improvement, profound knowledge.
Deming : Profound Knowledge
Profound knowledge is; appreciation for the system, theory of
variation, theory of knowledge, and psychology.
Appreciation for the system;.Every one in the organization
working to achieve overall optimization. Management most
eliminate internal competition.
Theory of Variation; Variation reduction is an important key to
quality. There are two types of variations; random and correctable.
We should concentrate on the later.
Theory of Knowledge; Knowledge comes from theory. Learning
can not occur in an organization without a theory of knowledge.
Psychology; Workers want to create and learn. Management’s
greatest challenge is to motivate workers to contribute their
common effort to achieve a common goal.
Deming’s 14 Points
1.Constancy of purpose toward improvement.
2.We can no longer live with defects and delays.
3.Forget mass inspection, rely on statistical process control (SPC).
4. Eliminate unqualified suppliers. Not just price, but Price + quality.
5.Work continually on the system, identify problems, resolve them.
6.Institute modern methods of training on jobs.
7.Responsibility of foremen is not productivity but quality, which in turn
improves productivity. Management takes immediate action on foremen
requests regarding improvement in elements of the system.
8.Drive out fear, so that every one may work effectively for the company.
9.Break down barriers between departments. Motivate team work.
10.Do not ask for more productivity, without providing methods.
11.Eliminate work standards that prescribe numerical quotas.
12.Break down barriers between hourly and permanent workers.
13.Institute a vigorous program for education and retraining.
14.Top management will push every day on the above 13 points.
Juran
He made his first trip to Japan after publication of his Quality Control
Handbook in 1951.
His method is close to that of Deming, but with two main differences.
1) Management of quality is not very difficult.
2) He places less emphasize on SPC.
His initiatives;
Quality begins by knowing what customer wants. Quality is fitness-for
use.
Almost 80% of quality defects can be controlled by commitment of
management to continuos improvement.
Quality management is 1) quality planning, 2) quality control, and 3)
quality improvement.
He showed high cost of low quality, and potentials of cost reduction
through quality improvement.

ISO 9000 Registration Process
• When an organization feels that its quality system is
good enough, it may ask for assessment.
• The audit begins with a review of the company's
quality manual. The audit team checks to see that the
documented quality system meets the requirement of
ISO 9000 and that the organization is practicing what
is documented.
• When the registrar is satisfied with the
recommendation of the audit team, it issues a
registration document to the company.
