Try the New Lean Hospitals AI Assistant (Free Preview + Founding Member Rate)

The Mistakes That Make Us is a recipient of the Shingo Publication Award from the Shingo Institute!
Hi :
I've been building something I'm excited to share with you.
The Lean Hospitals AI Assistant is an on-demand coaching and reference tool grounded in my Shingo-Award-winning book. You can ask it questions about Lean in healthcare -- daily huddles, gemba walks, A3 thinking, standardized work, psychological safety, error-proofing, and more -- and get answers that draw directly from Lean Hospitals or from broader Lean and TPS principles.
It's not a generic chatbot. When searching outside of my book, I've built guardrails into it so it stays consistent with how I think about Lean: systems thinking, Respect for People, improvement done with people rather than to them, and cost reduction as a result of better quality and flow -- not the goal itself. If you ask it something the book doesn't cover, it will say so honestly rather than making things up.
A few things that make it useful:
- Book Search mode pulls directly from Lean Hospitals and cites specific chapters.
- General mode expands beyond the book but stays philosophically consistent -- no "Lean is for speed, Six Sigma is for quality" nonsense.
- Coach mode asks you questions back, Socratic-style, to help you think through real challenges.
- Guided Prompt Packs walk you through multi-step conversations on topics like Building Psychological Safety, A3 Problem Solving, and Preparing for a Gemba Walk.
- It adjusts its responses based on your role -- whether you're an executive, a manager, frontline staff, a consultant, or a student.
- It also works in various languages -- for example, ask in Dutch and it will reply in Dutch.
Try it free. You can ask a few questions at no cost to see if it's useful for you:
Founding member rate. If you like what you see, use code FOUNDER at checkout to lock in a special annual rate as an early subscriber. This rate won't last forever -- it's for people who get in early and help shape the tool.
Your feedback matters. This is still evolving. I read every piece of feedback that comes through the tool, and early test users and subscribers are directly influencing what gets built next. If something is off, I want to know. If something is surprisingly helpful, I want to know that too.
Give it a try and let me know what you think -- just reply to this email.
In classic Lean Startup mode, I'm trying to figure out:
- The technical features to build (or remove)
- The business model around a platform like this
Thanks for your help and support,
Mark

Join Me in Japan: A Lean Healthcare Accelerator Experience
To learn more about the planned itinerary, cost, and other details, please reply to this email. Early bird and group rate pricing options are available.
Let's Work Together
As we get further into the new, I have room to take on a few new coaching and advisory clients.
If you're leading change and grappling with challenges like:
- A Lean journey that feels stalled or surface-level
- Teams that hold back instead of speaking up
- Metrics that create noise instead of clarity
- Improvements that fade instead of taking hold
- A culture that talks about learning—but rarely follows through
You’re not alone—and you don’t have to figure it out alone.
Through virtual coaching, I work with leaders across industries to strengthen psychological safety, build a true culture of continuous improvement, and lead with greater clarity and confidence—even when the path forward isn’t obvious.
If you’re ready to make meaningful progress in 2026, let’s talk.
