Deming’s PDSA vs Lean PDCA

My LinkedIn reply to a post on Lean’s use of the Plan, Do Study, Act (PDCA) cycle.

Common Mistakes with the PDCA and also its History |Allaboutlean.com .  Overview of the main causes of failures in a PDCA which will cause lean projects to fail. Also, the history…

 

For a history on the PDCA and comparison of the PDCA to the Deming-based PDSA, I recommend the following article:  Foundation and History of the PDSA Cycle

The PDCA was developed in 1950. Deming improved upon the concept in 1986 and replaced the PDCA with the Plan, Do, Study, Act (PDSA) cycle. “Deming never embraced the PDCA.”

The “So what?”  For advocates of Continuous Quality Improvement (CQI), we need a better strategy for leveraging the various methodologies and tools.

Deming is the only expert that correctly identified that reducing variation from the ideal is THE key to CQI.

Employee Suggestions: Deming versus Lean

LinkedIn reply to a “re-post” of a 2007 post at leanblog.org on the topic of employee suggestions:

A Different “Lock Box” No, this isn’t about Al Gore and his infamous Social Security ‘lock box.’ This is about suggestion boxes that we sometimes see hanging on[..]

The contributions of W. Edwards Deming provides context for suggestions.  For instance, if you ask employees “What’s not perfect ?” , the suggestion box would always be overflowing.

The follow-up question is asking if the “imperfection” are recurring (common cause variation), or represent a temporary effect (special cause).  The majority of the imperfection will be common cause variation that requires a permanent change in the system.

Deming also accurately estimated that failure to understand variation resulted in a situation where 95% of change results in no improvement.

I’ve seen too many “lean” projects waste resources overreacting to a special cause and too many claiming success from changes that could not be sustained.  Assess your knowledge of variation at the following:  http://successthroughquality.com/uploads/3/4/5/1/34513631/a_quick_assessment_of_your_quali.pdf

The fact that the topic was re-posted from 2007 indicates the need for application of a better methodology. Without a change in strategy, this post  can be re-posted in another 9 years.

LinkedIn Post Reply: A New Theory For Transforming Society

A New Theory for Transforming Society by Jim Rough : In 1993 I had a mind-blowing insight about how to transform our society so we could solve many of our most intractable issues. Since that moment I’ve been explaining, experimenting and developing the idea —published a book about it (“Society’s Breakthrough! Releasing Essential Wisdom and Virtue in All the People“);” hosted a TV show; co-founded a non profit organization (The Center for Wise Democracy); convened conferences, gave talks, etc.  Recently on Skype I was getting reacquainted with an old friend, Jim Wanless, and wow. Jim’s questions brought out a whole new way of explaining the idea. (See the informal, edited, 23 minute video.)

Jim – great concept – enjoyed the video. I think an additional component that would enhance the transformation strategy is integrating a more explicit knowledge and application of the variation principle. This principle creates a new standard for Quality Leadership that “We the People” can apply in working towards a more- perfect union.  A summary of the variation principle applied to a “controversial issue” such as abortion is available at the following link.  I think your dynamic facilitation  concept  aligned with the explicit aim to reduce variation would help reinforce a better way of making the types of changes that to improvements that can be sustained.

Resolving Controversial Issues – Abortion Issue:

On major change, the first step in Kotter’s 8 stage process for leading change is to start with a sense of urgency. As you mentioned, a “crisis” can provide the extrinsic motivation to bring about needed change.  However, sustaining a quality approach requires people to be more intrinsically motivated which is supported by the fact that variation either gets better or it gets worse.
