In this episode, Bill Bellows and Andrew Stotz discuss David Garvin's 8 Dimensions of Quality and how they apply in the Deming world. Bill references this article by Garvin: https://hbr.org/1987/11/competing-on-the-eight-dimensions-of-quality TRANSCRIPT 0:00:02.4 Andrew Stotz: My name is Andrew Stotz, and 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 31 years helping people apply Dr. Deming's ideas to become aware of how their thinking is holding them back from their biggest opportunities. This is the Misunderstanding Quality series, episode two, The Eight Dimensions of Quality. Bill, take it away. 0:00:30.4 Bill Bellows: Welcome back, Andrew. Great to see you again. All right, episode two, we're moving right along. So in episode one, which the title I proposed, waiting to see what comes out, the title I proposed was, Quality, Back to the Start. And that was inspired by some lyrics from Coldplay. Anyway, but this is a, it's going back to my start in quality and last time I mentioned discovering Taguchi's work long before I discovered Dr. Deming. In fact, Gipsie Ranney, who is the first president of the Deming Institute, the nonprofit formed by Dr. Deming and his family just before he passed away, and Gipsie became the first president and was on the board when I was on the board for many years. And I spoke with her nearly every day, either driving to work or driving home. And once, she calls me up and she says, "Bill," that was her Tennessee accent, "Bill." 0:01:50.5 BB: She says, "It says on The Deming Institute webpage that you infused Dr. Taguchi's work into Dr. Deming's work," something like that, that I... Something like I infused or introduced or I brought Taguchi's work into Deming's work, and I said, "Yes." I said, "Yeah, that sounds familiar." She says, "Isn't it the other way around?" That I brought Deming's work into Taguchi's work. And I said, "No, Gipsie," I said, "It depends on your starting point. And my starting point was Dr. Taguchi." But I thought it was so cool. She says, "Bill don't you have it? Don't you... " She is like, "Isn't it the other way around?" I said, "No, to me, it was all things Taguchi, then I discovered Dr. Deming." But I was thinking earlier before the podcast, and I walked around putting together how, what I wanna talk about tonight. And I thought, when I discovered Taguchi's work, I looked at everything in terms of an application of Dr. Taguchi's ideas. 0:03:29.7 AS: And one question about Taguchi for those people that don't know him and understand a little bit about him, was he... If I think about where Dr. Deming got at the end of his life, it was about a whole system, the System of Profound Knowledge and a comprehensive way of looking at things. Was Taguchi similar in that way or was he focused in on a couple different areas where he really made his contribution? 0:04:03.9 BB: Narrower than Dr. Deming's work. I mean, if we look at... And thank you for that... If we look at Dr. Deming's work in terms of the System of Profound Knowledge, the elements of systems psychology, variation, theory of knowledge, Taguchi's work is a lot about variation and a lot about systems. And not systems in the sense of Russ Ackoff systems thinking, but variation in the sense of where's the variation coming from looking upstream, what are the causes of that variation that create variation in that product, in that service? 0:04:50.9 BB: And then coupled with that is that, how is that variation impacting elsewhere in the system? So here I am receiving sources of variation. So what I deliver it to you has variation because of what's upstream of me and Taguchi's looking at that coupled with how is that variation impacting you? So those are the systems side, the variation side. Now, is there anything in Deming, in Taguchi's work about psychology and what happens when you're labelling workers and performance appraisals and, no, not at all. 0:05:37.6 AS: Okay, got it. 0:05:38.4 BB: Is there anything in there about theory of knowledge, how do we know that what we know is so? No, but there's a depth of work in variation which compliments very much so what Dr. Deming was doing. So anyway, so no. And so I discovered Taguchi's work, and I mentioned that in the first episode. I discovered his work, became fascinated with it, started looking at his ideas in terms of managing variation to achieve incredible... I mean, improved uniformity to the extent that it's worthwhile to achieve. So we were not striving for the ultimate uniformity, it's just the idea that we can manage the uniformity. And if we... And we'll look at this in more detail later, but for our audience now, if you think of a distribution of the variation in the performance of a product or a service, and you think in terms of... It doesn't have to be a bell-shaped distribution, but you have a distribution...
