In this episode, Bill and Andrew discuss variation, the impossibility of true interchangeability and why we need to apply "shades of gray" thinking at work. Bill shares the key question that will take your organization beyond "meets specifications" and help improve your processes, so you can delight your customers.
TRANSCRIPT
0:00:02.8 Andrew Stotz: My name is Andrew Stotz. I'll be your host as we continue our journey into the teachings of Dr. W Edwards Deming. Today, I'm continuing my discussion with Bill Bellows, who has spent 30 years helping people apply Dr. Deming's ideas to become aware of how their thinking is holding them back from their biggest opportunities. The topic for today is 20th century quality, Bill take it away.
 
0:00:28.2 Bill Bellows: Thank you, Andrew. So the running joke on the 20th century quality is we could have said 19th century, and sadly it's still 21st century. And what do I mean by that? In our second episode, we've talked about the two questions of quality management. Question one, does this characteristic, does this product, does this thing meet requirements? There's only two answers. That's 19th century quality, that's 20th century quality, and by and large, that's 21st century quality. And my hope is that our conversation inspires people to move into question two, which opened opportunities for as you're talking about opportunities for investment, opportunities for doing amazing things, when we get out of the black and white of question one into the shades of gray, of question two. That's, that's so...
 
0:01:26.5 AS: So what century are we in now?
 
0:01:29.1 BB: I think the 21st.
 
0:01:30.5 AS: 21st. My goodness. People always get, I always get confused. We're in the two thousands, but that's a 21st century. And 19th century is the 1800s.
 
0:01:46.7 BB: Well...
 
0:01:47.5 AS: 20th century would then be from 1900s until 2000 or 1999.
 
0:01:54.3 BB: The... And just for some more clarity, and I was doing some research earlier today, but there's a great tie between question one and 19th century 20th centuries still: question number one, does this meet requirements? A lot of that ties back to this whole concept of interchangeable parts. Which is not what we do in the garage when we're in the garage building something - that's 21st century quality, because we design it, we buy the stuff again, whether you're building something in the kitchen, in the backyard, and we put it all together with a 21st century, a Deming-Taguchi approach to quality, which means we're not looking at the parts in isolation we're looking at how they come together, the idea of interchangeable parts, and the... A name that I usually find as being the father of this concept of interchangeable parts. People talk about Eli Whitney.
 
0:03:02.3 BB: But Eli Whitney heard about interchangeable parts from the first American to hear about this concept, who was Thomas Jefferson. And he heard about it when he was US Ambassador to France, in 1802 timeframe, he was Jeff, he was George Washington's ambassador to France. And while there he came across a Frenchman by the name of Andre Blanc, B-L-A-N-C. And Blanc is considered the... Not the father of interchangeable parts. There's a French general in the 1770s had this idea of you're in the battlefield, you've got all these broken weapon systems and I can't cobble together this cannon with these wheels to be able to continue fighting the battle because they're all crafts built with craftsmanship, which means these things don't come together. So this general had the idea, and I like to tell people, Blanc is the one who got the marching orders to go put this concept into practice. And so he's given credit for being the one to work through the details.
 
0:04:17.1 BB: And what I was reading earlier tonight I've done other reading on this before, but it was, Jefferson went to a presentation by Blanc, heard about the ideas. Jefferson wrote a letter to John
