• Failure Mode 1:• Copy “tools” only without making work self-
diagnostic• Failure Mode 2:
• Workaround problems even when they are recognized
• Failure Mode 3:• Don’t share systemically what has been
learned locally• Failure Mode 4:
• Don’t develop the capabilities of others to design work, improve work, and institutionalize new knowledge
Why Do We Fail?
![Page 7: Continuous Improvement "System-ism"](https://reader036.vdocuments.site/reader036/viewer/2022070301/546a7923af7959842c8b6bb0/html5/thumbnails/7.jpg)
1. Relying on technology to solve problems2. Seeking examples to follow rather than developing
solutions (implement the new, cool thing)3. Excuses, such as "our problems are different“4. Relying on quality inspection rather than improving
product quality5. Reliance on quality control departments to solve
problems rather than management, supervisors, and production workers solving problems
6. Placing blame on workforces who are only responsible for 15% of mistakes when the system designed by management is responsible for 85% of them
Effects (Symptoms) Of Failure...

• Failure Mode 1:• Copy “tools” only without making work self-diagnostic
• Causes:• We look only with our eyes...so we only see what is visible
Causes...
"I think that people here expect miracles. American management thinks that they can just copy from Japan—but they don't know what to copy!“
- W. Edwards Demming

• Failure Mode 2:• Workaround problems even when they are recognized
• Causes:• Scientific Problem Solving isn’t taught• Problems aren’t seen as opportunities• Focus on Short Term Goals
• This week
• This Month
• This Quarter
• This Fiscal Year
Causes...

• Failure Mode 3:• Don’t share systemically what has been learned locally
• Causes:• No predefined method of sharing• No way of knowing when sharing has not occurred• Running an organization with functional “Silos”
Causes...
![Page 11: Continuous Improvement "System-ism"](https://reader036.vdocuments.site/reader036/viewer/2022070301/546a7923af7959842c8b6bb0/html5/thumbnails/11.jpg)
• Failure Mode 4:• Don’t develop the capabilities of others to design work,
improve work, and institutionalize new knowledge
• Causes:• Problem Solving is thought of as a specialist role, rather than
a core capability of every worker to be developed• Problem Solving and the ability to develop problem solving in
others is not a key requirement of managers everywhere• Ignoring the importance of mentor / student ratio’s on the
plant floor.
Causes...

• Forget whatever “Cool” name you’ve given your CI Program – the name matters not
• Stop measuring CI by short term Goals – focus on customer satisfaction, profits will come
• Move away from functional silo’s of disciplinary “experts” – move towards organization built around products
• Give every employee a capable mentor – expect that every employee continue learning
Countermeasures

1. How to Design Work to see problems
• Make All work highly specified as to content, sequence, timing, and outcome
2. Insist on swarming problems• Problems must be immediately
addressed, both to contain their effects from propagating, and to trigger problem solving
Countermeasures (what to teach)
![Page 14: Continuous Improvement "System-ism"](https://reader036.vdocuments.site/reader036/viewer/2022070301/546a7923af7959842c8b6bb0/html5/thumbnails/14.jpg)
3. Problem Solving Using the Scientific Method
• Any improvement must be made in accordance with the scientific method, under guidance of a teacher, at the lowest possible level within the organization
4. Leaders Must be Teachers• The most senior management
level has to own the capability development process – it must cascade downhill

The FOUR Levels of Process Design
1. Defining objectives/outputs for the system
2. Creating pathways by assigning responsibilities
3. Connecting adjacent nodes on the pathway
4. Designing individual work activities

Problem Solving is Mostly Simple...
Both Demming and Ishikawa agreed that basic problem solving will solve up to 95% of all problems typical in manufacturing. The problem is one of data collection and rigorous execution of a structured methodology.

Basic PDCA* Problem Solving
Plan• Definition &
Analysis
Do• Try Counter-
measure
Check• Confirm
result
Act• Standardize
or revise
Key Points:
•Constantly repeat the cycle as a problem solving tool & management routine
•Was the Toyota starting point for quality improvement in the 1960’s.
*Originally known as the Shewart Cycle, developed by Walter Shewart in his 1939 book titled “Statistical Methods From the Viewpoint of Quality Improvement” and later popularized by Edward Demming.
