Last weekend, at a patient safety conference, I heard a physician talk about “robust process improvement” and this, thankfully, included an endorsement of Lean methods.
That's the good news.
The bad news was that the physician who was presenting trotted out what appeared to be a tired and incorrect framing of Lean and Six Sigma, as shown in the picture below (this conference used the widest widescreen slide format I've ever seen, by the way):
It's an example of Lean As Mistakenly Explained (or a form of L.A.M.E.), where Lean is “about waste and speed” and “you need Six Sigma for quality.”

So that brings me to a post I wrote in 2011, today's Throwback Thursday. I wrote the post in 2011 and I don't need to write it all again. That post was titled:
Lean is not about “making bad stuff faster” if Six Sigma is not involved. Remember this video I posted last year?
It's ironic that the speaker talks about “confusion.” He's horribly confused. He probably still is.
I'm going to politely and respectfully reach out to the Joint Commission presenter and try to convince her that Lean is about both quality and flow… just ask Toyota.
Also check out this good piece by Nicolas Ruhmann on LinkedIn: “Lean Six Sigma Could Blind You.”
We'll have to keep working to clear up these misunderstandings.
