Mistakes and Errors: A Circular Definition; Leadership Matters
Blog post link
When writing or speaking, I use the words “mistake” and “error” interchangeably. The definitions in some dictionaries are comically circular.
Dictionary.com defines an error as:
“a deviation from accuracy or correctness; a MISTAKE, as in action or speech.”
It also defines a mistake as:
“an ERROR in action, calculation, opinion, or judgment caused by poor reasoning, carelessness, insufficient knowledge, etc.”
So, a mistake is an error, and an error is a mistake.

The Pitfalls of Safety Bonuses in Lean Factories: A True Story
Blog post
I was talking recently with a trusted friend in the Lean community. He told me a story. It's certainly believable, even if it's second or third-hand to me.
He had no reason to make up a story like this.
A relative of his works in a U.S. factory. Yes, we still have factories here.
I'll call this relative of my friend “Guy,” which is pronounced the American way, not the French way.
Guy's factory would claim to use Lean methods and might even claim a “Toyota Production System” label as its inspiration.

Psychological Safety vs. Psychological Comfort: Understanding the Distinction
Blog post link
The Big Picture: In the Lean community and beyond, some people mistakenly equate “psychological safety” with being comfortable all the time. This misconception can undermine the true essence of psychological safety in the workplace.
Psychological safety is not about constant comfort or shielding managers from discomfort. Synthesizing a few definitions of psychological safety, I say it's a person's belief, feeling, or perception that it's safe enough to speak candidly about things including:
Mistakes
Problems
Ideas
Differing views
without fearing marginalization or punishment.
What Psychological Safety Really Means

Preventing Surgical Errors: Effective Strategies Over Warning Signs in Operating Rooms
The blog post
IMAGE: A sign that reads "CAUTION: DON'T OPERATE ON THE WRONG SIDE"
It's silly, right? I've never seen a sign like this in an operating room. And I'm not advocating for them. It's not the right approach for quality and patient safety.
If warning signs actually prevented mistakes, and given that a vast majority of mistakes are caused by human factors (like fatigue) and systemic factors (like being behind schedule because instruments were delivered late to the O.R.)…1) A sign like this would be posted in every operating room
and2) Wrong-site, wrong-side, and wrong-patient surgeries would never occurBut, of course, it's not that simple.What works?Mistake-proofing works.

Celebrating 100 Years of Shewhart’s Control Charts: A Century of Quality Management
The blog post
TODAY marks the centennial of one of the most significant innovations in quality management: the control chart. 🎂 🎉 🎆
In the early 1920s, Walter A. Shewhart, working at Bell Labs, recognized the need for a statistical method to monitor and control manufacturing processes.
On May 16, 1924, Shewhart created the first “control chart,” a tool that distinguished between common cause variation (inherent in the process) and special cause variation (due to specific, identifiable factors). This simple yet powerful distinction laid the foundation for modern statistical process control (SPC). Control charts were dubbed “Process Behavior Charts” by Donald J. Wheeler Ph.D.)
The latest and greatest of the control charts is the “XmR Chart” — as Wheeler wrote about in Understanding Variation and I wrote about in Measures of Success (a book that has a foreword written by Wheeler).

Do We Need Another Share in the See, Solve, Share Model of Continuous Improvement?
Blog post
I love Steve Spear‘s emphasis on a Toyota-based Lean model of:
“See, Solve, Share”
See problems, solve problems, and share what worked as countermeasures. That's the ideal, and it's powerful where it exists.
At Toyota, and companies like it, there's an understanding that speaking up about problems leads to a constructive response from leaders.
That's not always true at other companies that are starting or attempting their “Lean Journey.”
The Psychological Safety that might be taken for granted at Toyota must be actively cultivated in a company before continuous improvement can really take root, let alone take off.
I think the model could also be stated as:
“See, Share, Solve, Share”
