Celebrate Father's Day With These Grand Daddies of Quality - GoLeanSixSigma.com

Throughout the year we celebrate the birthdays of the “Grand-Daddies” of Quality (also known as “Quality Gurus”). These are the founders of modern day process improvement!

We owe this venerable group a debt of gratitude for all of the concepts, tools and methods we often take for granted. If you ever wondered where a Fishbone Diagram came from or who invented the 5 Whys, rest assured it’s one of our fabulous Quality forefathers. Join us in wishing these Grand-Daddies a very happy Father’s Day!
