Principles of Lean Thinking

Welcome to my website.


Most of you are coming to this website because you have been listening to my latest book, Developing Lean Leaders at All Levels. Thank you for making that purchase.

This website represents my humble origins. I created an online course in 2006 which was taken by over 100,000 people from over 40 countries around the world. This was my first online course creation. The video quality and audio quality was poor and does not meet today’s quality standards.  Rather than dropping the course, I have made it available to all those that are interested in the topic of Lean Management. It is now FREE!

I have also chosen to give everyone access to a PDF version of my book, OEM Principles of Lean Thinking; again for FREE!. My hopes are that you will train new employees with these materials.

Simply email me at and share a little story with me about who you are and how you plan on using these materials. Then I will send you a link to access the book. If your story is compelling and you would like to train everyone in your organization – I will also give you access to quizzes that were created when this online course was developed. 

My dream is that the next time I do a webinar for business people; no one asks, “What is Lean?”
