I'll be teaching my "Better Metrics" workshop (aka "Measures of Success," ala my book) twice in June: Cambridge Investments - Open for Public Registration (Fairfield, Iowa) -- June 5 Lean Healthcare Transformation Summit (Chicago) -- June 13 After facilitating the Red Bead Experiment in the workshop, one other way I've found to simulate variation is an online simulation that's available, of all places, on the BBC website: "Can chance make you a killer?"

My favorite book, as I've written about before, is not a "Lean book" -- it's Understanding Variation: The Key to Managing Chaos by Donald J. Wheeler, PhD. It might look like a book about statistics...

As I've done before (and written about), I'll be facilitating the famed "Deming Red Bead Experiment" on Thursday at the Society for Health Systems...

My wife and I just got back from four days in Napa and Sonoma counties doing, ahem, "gemba walks" at a number of wineries,...
