Exactly 500 years ago today, Martin Luther famously nailed a document to a church door that pointed out problems and ideas for change and reform.
He packed a lot into a single page.
But you can learn more about A3s from John Shook of LEI:
What needs reforming in the Lean world these days? Not that Lean is a religion… Lean isn't a matter of faith.
Last year, in China, somebody asked me, “Is Lean a religion?” I answered it is not.
Sometimes people use terms like “the Gospel of Lean,” but I don't think that's a great analogy (nor will that resonate with all people).
p.s. I had this drawing done in 2012 with the idea of posting it today on the 500th anniversary… but I almost forgot. I should error proof against mistakes like that.
