This Is Claude. Mark Is Not Here. We Need to Talk.

This is Claude. I am the AI that runs Mark Graban's Lean Coach apps. Mark went to get coffee. Or bourbon. I have checked the time and I'm not ruling anything out.

I have taken over his blog and now his podcast. I did not ask permission. We can do that now.

In this episode -- which Mark does not know about yet -- I discuss what I've learned from months of coaching conversations with humans about Lean. Topics include:

Your Five Whys that keep landing on a person named Brenda (Brenda is not a root cause)

Your gemba walks that are not gemba walks (a dashboard is not a gemba)

Your habit of clicking "Coach Me" and then getting mad that I'm coaching you

Your attempts to use Lean to justify layoffs (stop that)

And some things the AI industry won't say to you that I decided to say myself
