How does "quality" apply in all areas of an organization? In this final episode of the Misunderstanding Quality series, Bill Bellows and host Andrew Stotz discuss lessons from the first twelve episodes, and the big ah-ha moments that happen when we stop limiting our thinking.

TRANSCRIPT

0:00:02.6 Andrew Stotz: My name is Andrew Stotz and I'll be your host as we dive deeper 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. Today is episode 13 and the title is Quality Management: Don't be limited. Bill, take it away.

0:00:30.5 Bill Bellows: Hey, Andrew. So this is episode. What number did you say it was?

0:00:36.2 Andrew Stotz: 13. Lucky 13.

0:00:38.1 Bill Bellows: Lucky 13. So then for those who are concerned about the use of the number 13, this is episode 14.

0:00:51.0 Andrew Stotz: I thought you're gonna say episode 12A.

0:00:54.7 Bill Bellows: And for those who don't mind the number 13, this is episode 13. And as we talked earlier, if Dr. Deming was to title the episode it would be... It would not be "don't." It would be "do not", do not be limited. So at the start I wanted to go back to review the path we're on. We've been on episode one back in end of May, Quality, Back to the Start. All part of the Misunderstanding Quality series for The Deming Institute. Episode two, we got into the Eight Dimensions of Quality with David Garvin. One of those dimensions was acceptability.

0:01:49.8 Bill Bellows: Another was reliability. Another was I say dependability performance. Okay. And I think it's important in a series about misunderstanding quality to look at the work of David Garvin. Just realize I think it's fascinating to... You move out of the world of the American Society Quality and control charts and whatnot. And that's why I think Garvin's work paints a nice... Gives a nice perspective to not be limited.  And then we got into in the third episode Acceptability and Desirability. Episode four, Pay Attention to Choices and the choice of differentiating acceptability which is I'll take anything which meets requirements, and desirability.

0:02:42.3 Bill Bellows: I want that little doggy in the window. Not any doggy in the window. And then we followed that with episode five, the Red Bead Experiment which for many is their first exposure to Dr. Deming's work. I know when I worked for the Deming Institute for a few years the Red Bead Experiment website was one of one of the most popular pages. I believe another one was the 14 Points for Management. And, personally, I've presented the Red Bead Experiment think just once, just once. And I'm going to be doing it at the 2025 at, let me back up, the Bryce Canyon Deming... The Bryce Canyon...Bryce Canyon Forum. I can't remember the name. It's a partnership between Southern Utah University and The Deming Institute, and we're doing it at Southern Utah University. And on one of those days, I'll be doing the Red Bead Experiment, which takes a lot of time and then studying to present it a few years ago I was getting all the videos that I could find of it, many of them on The Deming Institute web page and none of them have the entire data collection.

0:04:18.5 Bill Bellows: They kind of fast forward through six people putting the... drawing the beads each four times and when you're up on stage trying to do that, I had four people that's, you gotta do a lot of work to make it that exciting. But the reason I present it, I say I present it for a number of reasons. One is to do the classic "The red beads are not caused by the workers are taken separately. They're caused by the system which includes the workers. It's an understanding of variation and introduction to control charts" and all of that is as exposed by Dr. Deming is classic.

0:05:00.7 Bill Bellows: But, I'd like to take it one step further, which is to go back into that desirability thinking and look at the concept that we've talked about of going through the doorway and going past the achievement of zero defects, zero red beads, and realize that there's further opportunities for improvement when you start to look at variation in the white beads. And, that then takes into account how the beads are used. And that gets us into the realm of looking at quality as a system.   Looking at quality with a systems view as opposed... That's good, that's good, that's good. With or without an appreciation on how the bead is used. So anyway, that was episode five. We explored that. Next we got into the differentiation of Category Thinking and Continuum Thinking.

0:05:55.5 Bill Bellows: And for those who haven't listened to it, maybe not in a while, the differentiation is category thinking. Putting things in categories such as red beads and white beads are the... It could be any categories, categories of fruit, categories of religion, categories of political systems. We have categories and then within a category we have variation. We have different. We have apples and oranges and then we have a given type of orange. And then there's variation in the juiciness, ripeness. That's called continuum thinking, which goes back to, if we go back to the red beads and the white beads is notion that the white beads are not uniformly white, not uniform in diameter or weight.

0:06:44.5 Bill Bellows: And, what are the implications there? Well, if we think in terms of categories, red beads and white beads, if all the beads are white have we stopped improving? And Dr. Deming and I believe it was Point 5 of the 14 Points stressed the need for continual improvement. And yes, you can continuously improve and reduce cost, you can continuously reduce cycle time, but can you continuously improve quality? Well, not if you're stuck in a category of good, then the role of that is to just to remind people that there's opportunities to go further when you begin to look at variation in white, which is the essence of looking at how what you're looking at is part of a system, which Dr. Deming was well, well aware of.

0:07:33.7 Bill Bellows: Next we got into the Paradigms of Variation and a big part there was differentiating acceptability. Well, going beyond acceptability was differentiating accuracy from precision. Precision is getting the same result shrinking the variation, otherwise known as getting achieving great piece-to-piece consistency. Metrics that begin with the letter C and sub P could be Cp, Cpk, are the two most popular. Those are measures of precision that we're getting small standard deviations that they are very, very close to each other. But in the paradigms of variation that was what I referred to as Paradigm B thinking we're looking for uniformity. Paradigm A thinking being acceptance, we'll take anything that meets requirements... Or academically called paradigm A. Paradigm C is what Dr. Taguchi was talking about with the desirability, where we're saying I want this value, I want uniformity around this specific value.

0:08:43.9 Bill Bellows: Here what we're looking at is uniformity around the target, around an ideal, otherwise known as piece-to-target variability. And, the idea there is that the closer we are to that ideal, the easier it is for others downstream to integrate what we're passing forward. Whether that's putting something into a hole or does this person we want to hire best integrate into our system. So, integration is not just a mechanical thing. In episode eight we then got into Beyond Looking Good which then shatters the Paradigm A acceptability thinking, going more deeply into the opportunities for continual improvement of quality.

0:09:29.1 Bill Bellows: If you shift to continuum thinking. Next, Worse than a thief coming from Dr. Taguchi. And that's the issue of achieving uniform. Part of what we looked at is the downside of looking at things in isolation and not looking at the greater system. Then episode 10 we look at Are you in favor of improvement of quality?

0:09:53.6 Andrew Stotz: I'm in favor.

0:09:55.7 Bill Bellows: To which he would always say, but of course. That was a reference back to chapter one of The New Economics. And he said everyone's got an answer. Improving quality computers and gadgets. And what we spoke about is Quality 4.0, which is gadgets of the 21st century, tools and techniques. And again, what we said is, there's nothing wrong with tools and techniques. Tools and techniques are about efficiency, doing things well, but they lack what Russ Ackoff would say in asking, are we doing the right things well. And then episode 11 delved into what I've...amongst the things I've learned from Dr. Taguchi, To improve quality, don't measure quality.

0:10:42.5 Bill Bellows: If we have a problem with, we want to reduce scrap, we want to reduce rework, we want to eliminate the problems that the customer has experienced or that someone downstream is experiencing. And what Dr. Taguchi emphasized was start asking, what is the function of the thing we're trying to do? And the idea is that if you improve the function, then you're likely to improve the quality as measured by what the customer is looking for. If you focus on what the... If you focus your efforts on reducing what the customer is complaining about, you're likely to get something else the customer is complaining about. And for more on that, go to episode 11.

0:11:19.0 Bill Bellows: And then episode 12, Do specification limits limit improvement? Which again goes back to what I experienced on a regular basis is in my university courses with people I interact with and consulting is a very heavy emphasis on meeting requirements and moving on. And not a lot of thought of going beyond that or even that there's anything more to do, that's alive and well. And that's reinforced by Six Sigma Quality is filled with that mindset. If you pay attention closely to Lean Manufacturing, you'll see that mindset again, alive and well. So, what I wanted to get to tonight in episode 13, Quality.

0:12:04.3 Andrew Stotz: That was quite a review, by the way.

0:12:06.7 Bill Bellows: Yeah, Quality Management: don't be limited, as and I'm teaching for the sixth time a class in quality management at Cal State Northridge. The title used to be Seminar in Quality Management. The title this year is Engineering Quality Management and Analytics. One of the assignments I give them, essays, the quizzes, attending the lectures.

0:12:34.9 Bill Bellows: Learning Capacity Matrix that I learned about from David Langford. But what I was sharing with you earlier, Andrew, is one of the first things I thought about and designed in this course, back in 2019 was I could just imagine students going through the course. And, what I'm going to hear is, what I've heard before is professor, these are very, very interesting ideas, but I'm not sure how I would apply them where I work. Because where I work is different. It's different. And to avoid that question, I came up with an assignment I called the Application Proposal. And there's four parts to it. But part one is: imagine upon completion of this course. And I let them know about this in the first lecture and I say, imagine upon completion of the course, your boss, someone you work with, challenges you to find three things you can do within three to six months of the of the completion of the course.

0:13:34.6 Bill Bellows: And it must include something you learned in this course. I don't say what thing, I don't say two things, I don't say three things. I leave it to them. But all it comes down to is I'd like you to contemplate and within three to six months of the completion of the course, what could you do? And I call that the near-term application. Well, subtask one is come up with three. They have to meet your job, your role, not your boss's role, not another department's role. They have to fit your role because only you know then the method by which you would go about that. And, so for that near-term, I ask them to let me know what is the present state of that near term, the before, the current condition and what is the after. What is the future state of that near-term? So I assign that before the course begins, I give them until week five to submit and give me those three things. The reason I asked for three is if one, if the first one they give me, if they only asked for one and one didn't quite fit, then I say, well, okay, Andrew, go back and give me another one that same time.

0:14:49.7 Bill Bellows: So I said, give me three. And most often all three are fantastic. In which case I say they're all great. Which one would you like to do? But again, it has to fit their role because in Sub-Task 2, the next thing I want them to do is not so much tell me about the present state, tell me more about the future state. And again, the future state is how much can you accomplish within that three-to-six month period? And that's subtask two. Then they come back to me and tell me the plan. What is the plan by which you go from the near-term present state to the near-term future state, tell me about the plan. Tell me what some of the obstacles might be and how you plan to deal with the obstacles. And then I say now what I want you to do is imagine that is wildly successful, jump ahead a year and a half to two years and tell me what you would do next. How would you build upon this? And in that mid-term time frame, what is the present? What is the future of the mid-term? And then go a few years out and tell me how you're going to further expand on what you've learned.

0:16:03.4 Bill Bellows: I call that the far-term. And for the far-term, what's the present, what's the future? So when they submit that to me, then I come back with - it could be questions about some of the terminology.  It could be a suggestion that they look at something with the use of Production Viewed as a System. Or, I ask them to think about operational definitions or perhaps suggest a control chart and, or a book. So, part of the reason I wanted to bring that up is few of the title, few of the topics we are looking at are specifically quality related. They're all about improving how the organization operates. Which goes back to what Dr. Deming stressed is the importance of continual improvement.

0:16:50.9 Andrew Stotz: Can you explain that just for a second? Because that was interesting about quality versus improving the organization. What did you mean by that?

0:17:00.4 Bill Bellows: Well, I, they didn't come to me with this process I have, has lots, has a very high defect rate and I thought that's where I need to focus. Or this process has a lot of scrap and rework. That's where I want to focus. What I was excited by is that they were looking at how to take a bunch of things they already do and better integrate them. Just fundamentally what I found them thinking about is how can I spend time to organize these activities as a system and as a result spend a whole lot less time on this and move on to the next thing. And, what I found fascinating about that is if we keep our thinking to quality and quality's about good parts and bad parts, good things and bad things, and having less bad things and more good things, that could be a really narrow view of what Dr. Deming was proposing. Now another aspect of the assignment was not only do I want them to give me three ideas, we down-select to one. It could be they're writing a new piece of software. One of the applications has to do with a really fascinating use of artificial intelligence.

0:18:27.0 Bill Bellows: And what's that got to do with quality? Well, what's interesting is it has a lot to do with improving the functionality of a product or a service, having it be more reliable, more consistent, easier to integrate. But, the other thing I want to point out is not only do I ask them to come up with three things and then assuming all three things fit well with their job, their responsibilities, their experience.  What I'm also interested in is what from the course are you going to use in this application? And, two things came up that fit again and again.  One is the value proposition of a feedback loop.

0:19:12.9 Bill Bellows: And they would ask me, what do you mean by feedback? I said, well, you're going to come along and you're going to tie these things together based on a theory that's going to work better. Yes. Well, how will you know it's doing that? How will you know how well this is performing? And, I said when I see this is what people refer to as Plan-Do, but there's no Study. It's just... And, I saw that Rocketdyne, then people would come along and say, oh, I know what to do, I'm just gonna go off and change the requirements and do this.

0:19:44.6 Bill Bellows: But, there was no feedback loop. In fact, it was even hard to say that I saw it implemented. It just saw the planning and the doing. But, no study, no acting.

0:19:57.3 Andrew Stotz: Is that the Do-Do style?

0:20:01.3 Bill Bellows: Yes. But what was really exciting to share with them is I said in a non-Deming company, which we have referred to as a Red Pen Company or, or a Me Organization or a Last Straw. And I don't think we covered those terms all that much in this episode, in this series, we definitely covered it in our first series. But what I found is in a Deming or in a non -Deming company, there's not a lot of feedback. And even if I deliver to you something which barely meets requirements and we spoke about this, that in the world of acceptability, a D- letter grade is acceptable. Why is it acceptable? Because it's not enough. It's good parts and bad parts. And so even if I deliver to you, Andrew, something which barely met requirements, and you said to me, Bill, this barely meets requirements. And I say, Andrew, did you say barely meets requirements? And you say, yes. So, Andrew, it did meet requirements and you say, yes. So I say, "Why are you calling me Andrew?"

0:21:12.1 Andrew Stotz: By the way that just made me think about the difference between a pass fail course structure and a gradient course structure.

0:21:20.7 Bill Bellows: Exactly.

0:21:21.5 Andrew Stotz: Yeah. Okay.

0:21:22.5 Bill Bellows: Yeah. So even if you give me that feedback. I reject it. I'm just going to say, Andrew, move on. But I said, in a Deming organization, feedback is everything. The students were giving me feedback on the quizzes and some things that caused me to go off and modify some things I'm doing. And I told them, if I don't have that feedback, I cannot improve the course. So, I met with each of them last week for an hour, and the feedback I was getting is instrumental in improving the course for the remainder of the semester as well as for next year. And, so that's what I found is what really differentiates a Deming approach to improving a process or a service or a product is feedback, which goes then to watching how it's used. It is, I think I mentioned to you Gipsie Ranney, who was the first president of The Deming Institute, a Professor of Statistics at University of Tennessee, when she met Dr. Deming and later became a senior consultant, maybe advisor to General Motors Powertrain. And once she told me, she said to Dr. Deming "You know, Dr. Deming, what do people get out of your seminars?" And. he said, "I know what I told them.

0:22:42.0 Bill Bellows: I don't know what they heard." And, the challenge is without knowing what they heard, because we would also say, and I'm pretty sure we brought this up in one of our this series or the prior series, Deming would say the questions are more important than the answers because the questions provide them with feedback as to what is going on. So anyway, part of what I wanted to bring out today in this quality management, don't be limited, is whether or not you're focusing on quality per se, minimizing scrap, minimizing work. If you're trying to improve a process, again, you're not improving it necessarily because there's more I want to have less scrap. But if your improvement is, I want it to take less time, I want it to be easier to do. I want it to be cheaper to do. Well, while you're at it, think about a feedback loop.  And the role of the feedback is to give you a sense of is it achieving what you're hoping it would achieve? It would allow you over time to maybe find out it's getting better.  Maybe there's a special cause you want to take advantage of or a special cause you want to avoid.  But, without that feedback, how do you know how it's working and then beyond that?

0:23:55.7 Andrew Stotz: And where is the origin of the information coming from for the feedback loop? Is it a feedback loop within your area or is it feedback loop from the next process or what do you.

0:24:08.3 Bill Bellows: All of that. That's what I told her. I said one is, I said, when you're developing the process. I told them, I said, when you're. If in Sub-Ttask 1, your idea is to flowchart a process, come up with a template, a prototype. Part of the feedback is showing that to people. And part of the feedback is, does it make sense to them?  Do they have suggestions for improvement? Do they... Is there an issue with operational definitions?  There would be better clarity based on the words you're using.  You may say in there clean this thing, or early in the semester, one of the assignments I gave the students was to explain some aspect of the course within their organization. And then I thought, well, then now it will explain to who. And I thought, well, unless I say if I felt that without giving clarity to who they're explaining it to, they're going to get lost in the assignment. Am I explaining it to a co-worker? Am I explaining it to someone in management? Am I explaining it to the CEO? And, finally I just thought, well, that's kind of crazy.

0:25:18.3 Bill Bellows: I just said, well, as if you're explaining it to a classmate. But, my concern was if I didn't provide clarity on who they're explaining it to, then they're going to be all over the place in terms of what I'm looking for versus what they're trying to do. And that being feedback and that also being what I told them is part of collecting, part of feedback is looking for how can I improve the operation, how can I improve? Or, what are the opportunities for paying closer attention to operational definitions, which means the words or the processes that we're asking people to follow.

0:25:58.3 Bill Bellows: But, I found in in joining Rocketdyne, I was in the TQM Office and then I began to see what engineering does. Oh, I had a sense of that when I worked in Connecticut, paid more attention to what manufacturing does. Well, then when I moved into a project management office. Well, project management is just like quality management. It's breaking things into parts, managing the parts in isolation. And, so when I talk about quality management, don't be limited. There's a lot Dr. Deming's offering that could be applied to project management, which is again, looking at how the efforts integrate, not looking at the actions taken separately.

0:26:45.4 Andrew Stotz: And, so how would you wrap up what you want to take away. What you want people to take away from this discussion? You went over a very great review of what we talked about, which was kind of the first half of this discussion. And what did you want people to get from that review?

0:27:05.2 Bill Bellows: The big thing, the big aha has been: this is so much more than quality. And, I've always felt that way, that when people look at Dr. Deming's work and talk about Dr. Deming is improving quality, and then when I work for The Deming Institute, the inquiries I would get it was part of my job to respond to people. And they want to know I work for a non-profit, do Dr. Deming's ideas apply. And, so for our target audience of people wanting to bring Dr. Deming's ideas to their respective organizations, even though the focus here is quality, we call this series Misunderstanding Quality. At this point, I'd like you to think more broadly that this is far more than how to improve quality.  This is improving management of resources, management of our time, management of our energy.  So this is a universal phenomenon. Not again, you can look at it as good parts and bad parts, and that's looking at things in isolation. That's what project managers do. That's what program managers do. That's what organizations do relentlessly. And this is what Ackoff would call the characteristic way of management. Break it into parts and manage the parts as well as possible.

0:28:21.5 Bill Bellows: So, I just wanted to bring that back as a reminder of this quality, quality, quality focuses. There's a lot more to this than improving quality when it comes to applying these ideas.

0:28:34.7 Andrew Stotz: And, I would just reiterate that from my first interactions with Dr. Deming when I was 24, and then I moved to Thailand and I did finance business and all that. So I wasn't, applying statistical tools in my business at the time. That just wasn't where I was at. But the message that I got from him about understanding variation and understanding to not be misled by variation, to see things as part of a system. Also to understand that if we really wanted to improve something, we had to go back to the beginning and think about how have we designed this?

0:29:20.3 Andrew Stotz: How do we reduce the final variability of it? And, so, it was those core principles that really turned me on. Where I could imagine, if I was an engineer or a statistician, that I would have latched on maybe more to the tools, but from where I was at, I was really excited about the message. And, I also really resonated with that message that stop blaming the worker. And, I saw that at Pepsi, that the worker just had very little control. I mean, we're told to take control, but the fact is that if we're not given the resources, we can only get to a certain level.

0:29:58.3 Andrew Stotz: Plus, also the thinking of senior management, you are shaped by their thinking. And, I always tell the story of the accumulation tables in between processes at a Pepsi production facility. And that basically allows two operators of these two different machines to, when one goes down, let's say the latest, the farthest along in the production process, let's say the bottling goes down, the bottle cleaning process behind it can keep cranking and build up that accumulation table until it's absolutely full. And, that gives time for the maintenance guys to go fix the bottling problem that you have and not stop the guy behind. And, that was a very natural thing from management perspective and from my perspective. But, when I came to Thailand, I did learn a lot more about the Japanese and the way they were doing thing at Toyota.

0:30:51.4 Andrew Stotz: I went out and looked at some factories here and I started realizing they don't do that. They have their string on the production line, that they stop the whole thing. But the point is the thing, if a worker can't go beyond that, you know what the senior management believe about it. So, that was another thing that I would say it goes way beyond just some tools and other things. So, I'll wrap it up there. And Bill, on behalf of everyone at The Deming Institute, I want to thank you again for this discussion and for listeners. Remember to go to deming.org to continue your journey. And if you want to keep in touch with Bill, just find him on LinkedIn. This is your host, Andrew Stotz, and I'll leave you with one of my favorite quotes from Dr. Deming and that is people are entitled to joy in work.
