Lean Blog Audio: Practical Lean Thinking, Psychological Safety, and Continuous Improvement
Lean Blog Audio is a short-form podcast featuring audio versions of articles from LeanBlog.org, written, read, and expanded by Mark Graban. Each episode explores practical Lean thinking, psychological safety, continuous improvement, and leadership—through real-world examples from healthcare, manufacturing, startups, and other complex work environments. Topics include learning from mistakes, reducing fear and blame, improving systems, and using data thoughtfully through tools like Process Behavior Charts. Episodes often go beyond the original blog post, adding fresh context and reflections.

A title change is not a culture change. In this episode, Mark Graban draws on his early experience at GM in the mid-1990s — where "foreman" became "team coordinator" overnight without anything else changing — to explore why renaming supervisors with Lean-sounding titles so often fails to deliver Lean results.

Three years ago, The Mistakes That Make Us came out. Around the same time, Elisabeth Swan published Picture Yourself a Leader. Both books' third birthdays felt like a decent reason to get together and talk.
On Thursday, May 7, at 1 PM ET, Elisabeth and I are co-hosting a live event on LinkedIn called “Still Learning: Mistakes and Leadership Lessons.” We will talk about what readers have shared with us, what has h...
Most AI tools answer your question with a 500-word essay full of numbered steps. You nod, close the tab, and carry on doing what you were already doing. The Lean Hospitals Coach is built around the opposite instinct -- asking questions before giving answers, the way good coaching actually works.
In this episode, Mark walks through how the tool works, why it runs on Claude instead of ChatGPT, and what makes coa...
TL;DR: A sound check, live song requests, and a naming regret — what watching Brandi Carlile perform taught me about specific problem-solving, vulnerability, and continuous improvement.
My wife and I got to see the amazing Brandi Carlile perform near Chicago on Friday night.
She is a multi-Grammy award-winning singer, musician, and songwriter — though calling her a solo artist would be a mistake...
TL;DR: Deming and Toyota's Fujio Cho asked the same uncomfortable question: why do management systems destroy motivation in people who started out wanting to do good work? The answer points to practices leaders can actually change.

TL;DR: In a 1993 speech, Toyota leader Fujio Cho said organizations can create their own Lean systems, but success depends on three principles: leaders going to the gemba, asking “why” to learn from problems, and respecting and motivating people — not copying Lean tools.

What if a book could become an interactive coach instead of a static reference?
In this episode, Mark Graban shares a behind-the-scenes look at his experiment turning the award-winning book Lean Hospitals into an AI-powered chat assistant embedded directly on his website. What started as a Friday afternoon curiosity quickly evolved into a working WordPress plugin, a subscription model, and a new way to deliver improveme...
In this episode, I explore the 1987 NUMMI Management Practices Executive Summary — a confidential General Motors report that documented why the joint venture between GM and Toyota was succeeding so dramatically.
What’s striking is how clearly GM’s own study team understood the real drivers of NUMMI’s performance. It wasn’t tools. It wasn’t discipline. It wasn’t copying Toyota’s production techniques.
It was leadership.
Th...
In this audio version of the post, Mark Graban reflects on a rare kind of CEO message—one that treats safety not as a compliance checkbox or slogan, but as a core leadership responsibility and a living example of Respect for People.
Drawing from the 2025 annual report and CEO letter from GE Aerospace and its leader Larry Culp, Mark explores what it means when safety truly comes first in SQDC—and how that ordering signa...
In this episode, Mark Graban reads and reflects on his LeanBlog.org post, “When a CEO Talks About the Work: Larry Culp, GE Aerospace, and Real Lean Leadership.”
The post examines a rare example of a Fortune 50 CEO—Larry Culp of GE Aerospace—describing operational excellence not through slogans or dashboards, but through safety, trust, and small frontline improvements that compound into real results.
This episode explores:

Many improvement efforts stall not because of poor strategy or missing Lean tools, but because people don’t feel safe speaking up.
In this Lean Blog Audio episode, Mark Graban explains why psychological safety is a foundational requirement for continuous improvement. Drawing from his book The Mistakes That Make Us and decades of experience in healthcare, manufacturing, and other industries, Mark explores how fear, blame...
When Ford and UAW leaders traveled to Japan in 1981, they expected to find better machines, tighter processes, and technical secrets. What they found instead was something far more powerful: a management system built on listening, trust, and respect for people.
In this Lean Blog Audio episode, Mark Graban revisits the 1981 Ford–UAW study trip to Toyota, Nissan, and Mazda through the reflections of Don Ephlin, one of th...
Twenty years after Toyota Culture was published, Jeffrey Liker’s lessons still expose why so many Lean efforts stall — and why Toyota’s thinking continues to matter in 2026.
In this episode, Mark revisits a three-part podcast series recorded in 2008 with Professor Jeffrey Liker, author of The Toyota Way and Toyota Culture. Together, they explored what most organizations miss when they try to “implement Lean”: culture is...
How should organizations think about using AI in Kaizen and continuous improvement? In this AudioBlog, Mark Graban argues that there are no clear answers yet—and that uncertainty is exactly why AI should be approached through small, disciplined PDSA cycles rather than big bets or hype-driven rollouts.
Instead of treating AI as an expert or decision-maker, Mark frames it as a thought partner—a tool that can support brain...
Why do Lean practices like pull systems and heijunka fail to take hold in so many organizations? In this AudioBlog, Mark Graban argues that the problem isn’t the tools—it’s how Lean is applied. Too often, organizations cherry-pick visible practices like 5S, huddles, or kaizen events while avoiding the harder work of adopting Lean as a complete management system.
This episode explores why foundational elements such as le...
In this Lean Blog Audio episode, Mark Graban reflects on an unexpected leadership lesson learned on the pickleball court. As a beginner unlearning decades-old tennis habits, Mark experiences firsthand how execution errors, muscle memory, and self-criticism can quietly undermine learning. A kind instructor and supportive playing partners provide timely feedback—without blame—turning mistakes into moments of growth.
The s...
In this episode, Mark reflects on a visit he made twenty years ago to the NUMMI plant in Fremont, California — the Toyota-GM joint venture that became legendary in Lean circles. What stayed with him wasn’t flashy tools or so-called Lean perfection, but a series of small, human moments that revealed how Lean actually works as a management system.
Through six short stories — a broken escalator, aluminum foil, an explanato...
Dwayne “The Rock” Johnson once joked that his incredible physical transformation came from one simple routine: working out six hours a day, every day, for twenty years. In this episode, Mark explores why that line from Central Intelligence mirrors how organizations misunderstand Lean. Many admire the “after” picture of Toyota, ThedaCare, or Franciscan St. Francis Health, but far fewer commit to the steady, everyday hab...
In this episode, Mark Graban flips roles and becomes the guest—answering five core Lean questions posed by longtime Lean thinker Tim McMahon of the A Lean Journey blog. These questions have been answered by many practitioners over the years, and they cut straight to the purpose, the misconceptions, and the future of Lean.
Mark shares how he first encountered Lean as an industrial engineering student, and how the system ...
In this episode, Mark Graban explores one of the most misunderstood — and most essential — principles of Lean: the commitment to no layoffs due to improvement. Drawing from his work with Johnson & Johnson’s ValuMetrix Services team and stories from Lean Hospitals, Mark explains why Lean cannot thrive in a culture of fear and why protecting people’s livelihoods is foundational to psychological safety.
