Asked to name the 5 S's, the manager gets every one wrong: "straighten, salami, stopwatch, Sasquatch, and salmonella." He can't explain how any of it helps the work. His only answer is that the consultant said so. That's the actual failure mode here, not the mangled Japanese. A leader who can't explain the reasoning behind a program can't sustain it, coach it, or adapt it when it stops working. The team ends up following instructions instead of understanding a problem-solving method, and that's the difference between Lean as a toolkit and Lean as a costume.

"Salami, Stopwatch, Sasquatch..." -- This Manager Has No Idea What 5S Means
Publishing strategist Wiebke Tasch reviews manuscripts for a living. She says she can tell within a few pages when a book was written by ChatGPT: paragraphs disappear, replaced by short, choppy sentences formatted like a social media post. It reads fast and looks flat, and readers notice. Her point isn't that AI has no place in writing. It's that overuse flattens voice, and voice is the thing readers are actually there for.

The AI Writing Pattern Editors Spot Immediately
A consultant tells an office to tape outlines around hammers, monitors, and coffee cups because "the best factories do this." No one asks whether any of it fits the work actually being done. This clip is a satire of what happens when 5S gets applied as a checklist instead of a way of thinking. Real 5S starts with understanding the work and removing friction for the people doing it -- not mandating tape and pen limits because a consultant said so.

This Office 5S Program Is INSANE (Lean Gone Wrong)
Publishing strategist Wiebke Tasch reviews manuscripts for a living, and she says AI-written chapters give themselves away fast. Same sentence structure. Same "it's not this, it's that" construction, over and over. Once you've seen it a few times, you can't unsee it. Her advice for authors: use ChatGPT for proofreading and unsticking, not for writing your book. Readers notice sameness, and it costs you the one thing AI can't replace, your own voice.

ChatGPT's Writing Style Problem: Why Editors Can Spot It Instantly
The biggest mistake authors make isn't in the writing. It's finishing the book, publishing it, and telling no one. Publishing strategist Wiebke Tasch explains why the first five days after launch function as a blueprint for a book's entire future on Amazon. The algorithm tracks how much traffic you drive in that window, then uses it to decide whether your book gets suggested to readers in your niche going forward, or quietly disappears.

The Biggest Book Marketing Mistake: Publishing, Then Going Silent
Publishing strategist Wiebke Tasch had built a bestselling book and a comfortable full-time income on Amazon -- enough to quit her PR job. Then one morning an automated email told her she had violated Amazon's terms, and both of her accounts and all of her books were deleted. No warning, no explanation, no human to appeal to. Her mistake: she had opened two accounts, one for a pen name and one under her real name, not knowing Amazon allows only one per person. This is Wiebke's favorite mistake, and losing everything became the start of her company, Digital Authors.

Amazon Deleted Her Bestseller Overnight | Wiebke Tasch
Andre DeMerchant showed up to one of his first Toyota manufacturing meetings without a problem to report -- and quickly learned that was the problem. In this clip from Episode 547 of the Lean Blog Interviews podcast, Andre contrasts two kinds of meetings. In his previous industry, everyone reported green while the operation ran in chaos. At Toyota, every leader brought a problem, because "no problems is a problem." Showing up without one meant you didn't understand your own operation. What makes the story work is what happened next. Andre wasn't blamed or shamed. The miss was treated as a development opportunity, a chance to learn from his peers what to bring next time. That reaction is the precondition that makes a problem-surfacing culture function. Watch or listen to the full episode: https://youtu.be/MbA96zgnZFs Thomas Cox and Andre's A3 on why Lean implementations struggle is a free download at https://txl-lab.com/lean. Subscribe for more on Lean leadership, psychological safety, and continuous improvement. Host: Mark Graban, author of The Mistakes That Make Us, Measures of Success, and Lean Hospitals.
Showing Up to a Toyota Meeting Without a Problem | Andre DeMerchant
At Toyota, every manager was expected to bring a problem to the meeting. Andre DeMerchant learned that the hard way when he showed up without one and found out that "no problems" was the actual problem. In this clip from Episode 547 of Lean Blog Interviews, former Toyota manufacturing manager Andre DeMerchant describes what happened next. He wasn't blamed, shamed, or criticized. He was coached. The miss was treated as a development opportunity, with an open invitation to ask questions of anyone in the room, including the executive vice president. That response is the heart of "no problems is a problem," and a living example of the psychological safety that real continuous improvement depends on. Host Mark Graban talks with Andre DeMerchant and Thomas Cox about why Lean implementations so often fail to stick, and why psychological safety has to exist before any Lean rollout begins. Watch or listen to the full episode: https://leanblog.org/547 #Toyota #Lean #PsychologicalSafety #ContinuousImprovement #Leadership #Kaizen #LeanManufacturing #Shorts
At Toyota, Having No Problems Was the Problem
Here's the YouTube description. The first two sentences carry the keyword and hook before the "Show more" cutoff. Why do so many Lean implementations struggle or fail to stick? Thomas Cox and Andre DeMerchant join Mark Graban to argue that psychological safety is a precondition Lean can't create on its own, using Chris Argyris's Model 1 vs Model 2 framework. Lean asks people to surface problems, admit mistakes, and stop the line without fear. That only works if psychological safety already exists before the rollout begins. Under pressure, most leaders default to Model 1 behavior (controlling, self-protective, blame-oriented, closed off), which is the opposite of what Lean needs. Thomas Cox is a management bench builder, co-founder of the Transformative Leadership Lab, and a certified Harada Method coach trainer. Andre DeMerchant is president of DeMerchant Healthcare Solutions and a former Toyota team member who started as a forklift driver and rose to manufacturing manager. 🔵 Andre's contrast: meat-packing meetings where no problems was the goal vs. Toyota meetings where showing up without a problem marked you as not understanding the work 🔵 Alan Mulally banning sarcasm at Ford, and Mark Fields reporting red and getting applause instead of fired 🔵 The carrot-and-stick fallacy and McGregor's Theory X vs Theory Y 🔵 Whether consultants succeed because of method or because they cherry-pick Model 2 clients 🔵 The published A3 as a living document and a C-suite assessment tool Episode page with links and more https://www.leanblog.org/547 00:00 Introduction and the problem: why Lean doesn't stick 02:25 Andre's origin story: from meat-packing chaos to Toyota 05:08 The moment Lean got real (showing up to a meeting without a problem) 10:42 Thomas's origin story and the ethical PIP 14:43 If we can't blame the frontline worker, why blame management? 17:48 Framing the A3 and the problem statement 19:30 Argyris Model 1 vs Model 2 24:28 Mulally at Ford: banning sarcasm and applauding "red" 27:44 Carrots, sticks, and why behavior actually changes 31:36 Root cause analysis: why Lean fails 36:29 Countermeasures: getting executives into Model 2 42:24 Consultants, cherry-picking, and converting Model 1 organizations 49:33 Get the A3 and the C-suite assessment 51:58 Closing reflections Subscribe for more conversations on Lean, leadership, psychological safety, and continuous improvement, in healthcare and beyond. #Lean #PsychologicalSafety #ContinuousImprovement #Leadership #LeanThinking #Kaizen #RespectForPeople #LeanManagement
