An Aussie Backpacker’s Workplace Frustration: The Universal Need for Better Leadership
The blog post
Last Sunday, in Frankfurt, Germany, I took part in a guided walking tour of the city.
Our group included a young professional from Australia in his early 20s. He has taken leave from work to travel, backpacking across Europe.
We had an opportunity to chat over lunch and a local “apfelwein” (hard cider). He lamented his frustrations at work.
He said, “My boss thinks he is giving clear direction to us. Then we do the work our best way… only to be criticized for not understanding the direction.”

Leadership Gone Wrong: The Cost of Prioritizing a CEO’s Ego Over Effectiveness
Episode blog post
A sad but true leadership tale:
“Unlike most CEOs who rely on their executive team to keep them informed, [redacted] relies on his team to keep him feeling good about himself.
And so whenever somebody would tell him something that he didn't know and make it very clear that he wasn't the smartest person in the room on each and every topic, he generally fired them.”

Starting the New Year with Global Leadership Resolutions: Building a Foundation of Psychological Safety
Read the blog post
During Katie Anderson‘s #JapanStudyTrip this past November, a participant shared an observation with me that resonated deeply:
“The biggest challenge is our blame culture. It's easier for people to do nothing because they don't get in trouble.
But if they make a mistake, they get punished.
And our company is successful enough that there's not a compelling reason for top leaders to change the culture.”
This isn't a story from the U.S., but the feeling is universal.
A workplace culture where individuals are punished for mistakes–especially when those mistakes have systemic causes–is a significant barrier to progress.
It's a global challenge, and addressing it requires rethinking how we approach leadership and learning.

Lost My iPhone in Tokyo: A Lesson in Japanese Kindness and Culture on My Japan Study Trip
Read the blog post: https://www.leanblog.org/2024/11/lost-iphone-japan-taxi-tokyo-kindness-culture/
I'm thrilled to be back in Japan for the first time in five years. Today is the start of Katie Anderson's Japan Study Trip (learn more about joining her in May 2025). It's great to be here for another week of learning and great experiences.
Little did I know, I'd kick off the trip by nearly losing my iPhone on the streets of Tokyo–a mistake that ended up teaching me a valuable lesson about Japan's culture of trust.

Ten Years Ago -- In the News Visiting a Japanese Lean Hospital
The blog post
Just over a week ago, I got back from Katie Anderson's Japan Study Trip. It was amazing! I have so much to write about and share.
But first, Facebook reminded me of something from exactly ten years ago–the second time I visited Japan with the Kaizen Institute.
I asked 2024 ChatGPT to translate this 2014 news story that's pictured below (with me sitting there and taking notes in the front row of the meeting room). See the English text below the image:

Surveying the Lean Global Connection Audience on Barriers to Speaking Up
The blog post: https://www.leanblog.org/2024/11/surveying-the-lean-global-connection-audience-on-barriers-to-speaking-up/
At yesterday's Lean Global Connection event, I posed a straightforward yet revealing question to the audience:
“What keeps you from speaking up at work?”
The responses illustrated two of the common barriers. I posed the survey options based on the research of Prof. Ethan Burris, from the University of Texas at Austin, who has found that fear and futility are the top two reasons why people choose to stay quiet.
For some, fear stood in the way–the fear of reprisal, being judged, or being seen as a troublemaker.
For others, the obstacle wasn't fear but futility–the belief that speaking up wouldn't make a difference. Four people, sadly, said BOTH were barriers.
And yet, amidst these challenges, eight people shared that they felt no barriers at all, a testament to the environments they work in. That is the ideal we should all strive for.
The survey results line up with the Burris research that shows futility is actually the biggest reason, not fear.

Just Call it “5S Six Sigma” Instead of “Lean Sigma” Please
Blog post
My whole career, I have worked with the Lean methodology (aka the Toyota Production System).
I've just really never done much with Six Sigma. I've read about Six Sigma. I took a Green Belt course when I worked at Dell in the late 90s. I've studied and used statistical methods (especially what I learned in my Industrial Engineering studies and at MIT), but I've never done anything I would call Six Sigma in my career.
I have respect for Six Sigma as a discipline, just as if I were a chef, I would have respect for pastry chefs. They can co-exist in the kitchen. You might both use whisks, but you have slightly different training to do different things. These roles aren't interchangeable, and neither are Lean and Six Sigma. That's one reason I get riled up about so-called “Lean Sigma” or “Lean Six Sigma.”
Most of the “L.A.M.E.” (Lean As Mistakenly Explained) examples that I see on the interwebs come from “Lean Sigma” discussions, especially on LinkedIn.
What are the fallacies that are thrown around? They include, but are not limited to:
Lean is about the average, Six Sigma is about the variation
Lean is about internal processes, Six Sigma is customer-focused
Lean is for efficiency; you need Six Sigma for quality (this one is the fault of Mike George and his books, many say)
Lean and Six Sigma are just toolboxes, and you use whichever is appropriate for the problem at hand
These are all incorrect, as somebody with good Lean training or Lean experience would realize.
