Dr. W. Edwards Deming was one of the great statisticians
employed by Stanford University to teach American industry about methods that
allowed them to rapidly ramp up production of war-time goods during World War
II. After the war, the Japanese leaders invited Deming to teach them these
techniques. They were an island nation, production capacity destroyed by the
war, and few natural resources, so they were desperate. He is generally
credited with turning their economy around and helping them become a factor in
the world economy. He then focused on improving the quality of American
industry through his process thinking methods.
Some of his oft-quoted comments are:
·
“Good
intentions are not enough. They must be accompanied by profound knowledge. Deming
often said, “People are doing their
best.” Workers and managers alike intend to do a good job but their
processes and knowledge may be limiting their results. Dictionary definitions
of profound and knowledge can be interpreted to mean deep understand of
perceived truth. It involves knowledge of variation, understanding that no
process is perfect, and variation always exists. Quality for international trade must be good enough to command a
market.” If the quality of the product or service is not sufficient to
entice people to buy it, there is no market.
·
“Better
quality is the answer to industrial survival in the western world.” Worldwide
communications are so efficient today that people know where they can find the
best value, i.e., quality vs. cost. People no longer have to accept poor
quality.
·
“How would
you know?” Without data, you
don’t know how to make proper decisions. We often expect people to know
information that they have no way of finding or analyzing.
·
“When a
system is stable, telling workers about mistakes is only tampering.” Using
statistical methods, like control charts, to analyze data allows people to take
correct action to improve the processes., and avoid incorrect action. If a
manager takes action on individual points, the variation will only be
increased. Deming called this action “tampering”. If the process is stable and
the mean is not acceptable or if the variation is to be decreased, the process
must be improved. Simply criticizing or making demands of the employees will
just make it worse.
·
“People
with targets and jobs dependent upon meeting them will probably meet the
targets, even if they have to destroy the enterprise to do it.” If the targets are arbitrary, people
will find a way to achieve them even if it has a detrimental effect elsewhere.
It the process is not able to achieve the desired target, the employee will
find a way to reach it, no matter at what cost. If the process is capable of
doing more than the target, the employee will tend to not go beyond the target.
·
“People
hope for instant pudding,” People want immediate results, but improving
quality is a long and never-ending journey. Dr. Noriaki Kano of the Science
University of Tokyo said, “I wish quality was easy but unfortunately it is a
hot and sweaty job.”
·
“Change is
upon us. It is not optional.”
We cannot ever rest on our laurels. Changes in market desires, technology,
transportation, communication, environment, and world politics contribute to
change in the business climate. We must constantly and forever change.
We will conclude with some of Dr. Deming’s famous quotations
in the next article. It is
interesting to note how they are standing the test of time.
