Deming’s 14 Points

1. Create a constant purpose toward improvement.
2. Adopt the new philosophy.
3. Stop depending on inspections.
4. Use a single supplier for any one item.
5. Improve constantly and forever.
6. Use training on the job.
7. Implement leadership.
8. Eliminate fear.
9. Break down barriers between departments.
10. Get rid of unclear slogans.
11. Eliminate management by objectives.
12. Remove barriers to pride of workmanship.
13. Implement education and self-improvement.
14. Make "transformation" everyone's job.


My Seven Takeaways

1. Always be looking for a better truth.
2. A system is the sum of its human parts.
3. Complexity is the enemy.
4. Variation is the enemy.
5. Make policies explicit.
6. Learn two new words (Kaizen and Kata).
7. Make people before making a service.


Why Are We Here?

"Create constancy of purpose
toward improvement of product and
service, with the aim to become
competitive, stay in business and to
provide jobs."

W. Edwards Deming
14 Points - #1


Werner Karl Heisenberg (1901 – 1976)

• Father of Quantum Mechanics
• Won Nobel Prize for Physics
• Uncertainty Principle
• Opened Pandoras Box


The Father of Scientiﬁc Management


“The Parable of a Frog”


Takeaway #1
Always be looking for a better truth.

"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."
W. Edwards Deming
14 Points - #2


Neo Taylorism

A Japanese Commentary on Taylor

“We will win, and you will lose.
You cannot do anything about it because your
failure is an internal disease.
Your companies are based on Taylor’s principles.
Worse, your heads are Taylorized, too.”

Konosuke Matsushita
Founder, Matsushita Electronics
1988


The Devops First Way: Systems Thinking


W. Edwards Deming (1900 – 1993)

• Father of Quality
• Understanding of the system
• Understanding human behavior
• Understanding variation
• WWII success credited to his quality
approach
• Taught Japan after WWII and
transformed quality
• In 1980 Transformed American quality
revolution
• The Foundations of Six Sigma


System of Profound Knowledge


Taiichi Ohno (1912 – 1990)

• Father of Lean
• Toyota Production System (TPS)
• Just in Time (JIT) & Pull
• Inventor of Kanban
• Eliminate Waste
• 5 Whys method as "the basis of
Toyota's scientific approach


Takeaway #2
A system is the sum of its human parts

"Break down barriers between
departments. People in research,
design, sales, and production must
work as a team, in order to foresee
problems of production and usage
that may be encountered with the
product or service."
W. Edwards Deming
14 Points - #9


Eliyahu M. Goldratt (1947 – 2011)

• Father of Theory of Constraints
• Published the Goal in 1984
• Drum-Buffer-Rope
• Like Deming he was a Physicist
• Five Focusing Steps for Managing
• Global vs Local Optimization
• Inherent Simplicity
• Current & Future Reality Tree


Inherent Simplicity


Current Reality Tree


Takeaway #3
Complexity is the Enemy

"Cease dependence on inspection
to achieve quality. Eliminate the
need for massive inspection by
building quality into the product in
the first place."

W. Edwards Deming
14 Points - #3


The Devops Second Way: Feedback Loops


Walter A. Shewhart (1891 – 1967)

• Father of statistical quality control
• Creator of Control Chart/Shewhart chart
• Creator of PDSA/PDCA
• Chance and Assignable Variation
• Another Physics guy
• Worked for Bell Labs
• “Statistical Method from the Viewpoint of Quality Control”
- 1939


Control Chart


Takeaway #4
Variation is the Enemy

"Improve constantly and forever the
system of production and service,
to improve quality and productivity,
and thus constantly decrease
costs."

W. Edwards Deming
14 Points - #5


Shigeo Shingo (1909 – 1990)

• Co-father of Lean
• Toyota Production System (TPS)
• Poka-yoke (mistake-proofing)
• Jidoka
• Single-Minute Exchange of Die (SMED)
• Standardized work & Kaizen
(Continuous improvement)
• Shingo Prize that recognizes world-
class, lean organizations and operational
excellence.


Andon Cord


Kanban for Software


Takeaway #5
Make Policies Explicit

"Institute a vigorous program of
education and self-improvement."

W. Edwards Deming
14 Points - #13


The Devops Third Way: Continuous Learning


Kata


(TWI) - Training Within Industry

learn-by-doing


Takeaway #6
Learn two new words (Kaizen and Kata)

"Use training on the job. "

W. Edwards Deming
14 Points - #6


Lean Startup Thread

Customer Development Model

33


Tora! Tora! Tora!


Final Takeaway #7
Make People Before Making Services

"The aim of supervision should be
to help people and machines and
gadgets do a better job. "
