Mistakes are inevitable—but how leaders and organizations respond to them determines whether they improve or repeat the same failures. These posts explore mistakes through a Lean lens: system design vs. “human error,” psychological safety, learning cultures, and leadership behaviors that turn errors into improvement rather than blame.
Drawing from healthcare, manufacturing, aviation, sports, and everyday work, this archive focuses less on who failed—and more on what the system made possible.
Mistakes are inevitable; learning is not. These posts align with ideas I expanded on in The Mistakes That Make Us, which examines how leaders, cultures, and systems determine whether errors become liabilities—or catalysts for improvement.

What’s the difference between a mistake and an error? When people search “mistake vs error,” they’re usually asking whether the two words mean different things — or whether one implies more blame than the other. Short answer: In most contexts,…
The other day, I was presenting at a company about “Psychological Safety as a Pre-Condition for Continuous Improvement.” It was a hybrid event and I noticed, during the Q&A period, that somebody on Teams chatted about me making a mistake.…
tl;dr: Shingo renamed “foolproofing” to poka-yoke (mistake-proofing) after the old term made a worker cry. The lesson holds: blame doesn’t prevent defects, and respecting people is what makes zero defects possible. I’m currently working on a Mistake Proofing class for…
