Managing Mistakes: Role of a Manager in Education (Part 6)

In this episode, David and Andrew ask: should we tell people when they make mistakes? How do educators manage mistakes in a classroom setting, after their organization/classroom is transformed by learning and implementing Deming?

0:00:00.0 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 David P. Langford, who has devoted his life to applying Dr. Deming's philosophy to education, and he offers us his practical advice for implementation. The topic for the day is, "should we tell people when they make mistakes?" We are continuing a discussion about Dr. Deming's section of the book, The New Economics. If you have the 3rd edition, that's page 86. If you have the 2nd edition, that's page 125. And this is a list that Dr. Deming has given us of 14 points. It's not The 14 points that we normally talk about, but these are... The title of this 14 points is called Role of a Manager of People. This is the new role of a manager of people after transformation, and we are on point number six. And I'll just read it before we get David to start talking on it, and that is this.

0:01:02.7 AS: "The role of a manager in a new style," basically he's saying, "If he understands a stable system. He understands... " And I know we can also say she, "understands the interaction between people and the circumstances that they work in. He understands that the performance of anyone that can learn a skill will come to a stable state upon which further lessons will not bring improvement of performance. A manager of people knows that in this stable state it is distracting to tell the worker about a mistake." David, take it away.

0:01:41.2 David P. Langford: Thank you, Andrew. It's good to be back again. Yeah, I was just reflecting on this list is... It's such a great list. I'm sure that when people first read through this book they kinda just take 30 seconds to read through the list and then you go on. I've been studying Dr. Deming's work for over 40 years now and still find so much insight into all these things. So if you go through this and you start thinking about, "Well, what can I do differently and where do I begin?" I was also thinking that, when I got my Master's in Administration, I never heard of any of this. I never heard of a stable state, control charts, theory. I never got any of this or had a list on to how to manage people, which would have been very helpful, very insightful. So if you're working at a university right now and you're a teacher of classes of administration, here's some good advice, take people through this list and they'll actually come out with capability of what to do. But now back to the list. So, the first thing he says is you have to understand a stable system.

0:03:01.1 DL: So we did a couple of previous podcasts on stable and unstable systems, and on face value, a lot of people think: "Okay, well, stable system, okay, well, it's working well." But Deming's thinking around a stable system is much, much deeper than that, and it has to do with statistical stability. And so if you understand a stable system, then the first thing you're gonna have to do is you have to find out, "Do I have a stable system?" And so often when I work with people, I'll just start with sort of disarming questions and say, "Hey, how are things going?"

[chuckle]

0:03:45.4 DL: And they'll usually say, "Well, it's going pretty good." And, "Okay, well, how do you know?" "Well, 'cause people are telling me that it goes pretty good." "Well, how many people do you manage? Oh well, I have like 30 people on the staff." So you're telling me that 30 people are telling you every day that things are going really well? "Well, no, one person told me." "Well, do we know what the other 29 think?" So, right there you realize a manager does not understand a stable system. They have no idea what they're doing, and the phrase in America is "you're flying by the seat of your pants" which basically means you're just…whatever is happening from day to day, you're just going with the flow, but you're not managing a stable system nor do you really understand it.

0:04:39.7 DL: So the first thing I wanna point out is that this is telling you, before you do anything, you have to understand the system. So you have to figure out, "Okay, what am I gonna collect data on? What's really important? How do I really understand if I have a stable system?" Then you're gonna have to set up that process and you're gonna have to do that for at least 12 data points, if not 20 data points. And in education that could mean 12 days, 12 months. It could mean long periods of time. Or the other thing is you have to go back into history and get that data for previous years. That's another way you can get the data points, put them on a run chart and see, "Is this system stable?"

0:05:32.7 DL: So what does that mean? Well, once you do that, you'll find out you have average performance over a long period of time. Okay? And usually there will be variation in that. Some data points will be higher and some will be lower. There are only three possibilities for a data point, up, down or the same. And that's called variability in a process over time. And so you have to understand that, and you can't understand that just by intuitively sort of going day by day going through things, because psychologically you're constantly reacting to a situation.

0:06:17.6 DL: You go home at the end of the day and your wife or your husband says, "How was your day, dear?" And, "Oh I've had a terrible day," and duh, duh, duh. But they usually don't say, "Well, how do you know it was a terrible day? How do you know it was worse than any other day, or better than any other day, or..." Well, until you actually understand a stable system and understand what's going on, you don't know really. You're reacting psychologically to that, and that's part of human nature.

0:06:47.5 AS: I wonder, David, would it be...do you think it would be...would it be proper to say that most systems that are kind of running, and haven't been looked at as to whether they're stable or not, are probably unstable?

0:07:04.3 DL: Not... My experience, I'd say 90% of my work has been in education, not business, etcetera, but what I found out is that intuitively people will stabilize a system over time. If they don't unintentionally do that, they kinda go nuts, they go crazy. Because one day they're in euphoria and the next day they're in hell, and then they're just... The roller coaster swings are so great that they'll usually leave the profession, go find something else. I used to see that a lot with new teachers, brand new teachers. And they call it the Fall Wall. So you start school and everything seems really great, and then you start to realizing, "Wow, this is work, and this is managing people, and this is every day, this is..." You're on and you're working through that, and then there's the Fall Wall of this huge depression cycle, and...teachers that stay with it and really have a love of kids and a purpose behind why they're there, they'll start to normally just stabilize the system. They may not get great results, but on average they're no worse or not much worse today than they were yesterday, or vice versa. But they're not gonna get a breakthrough in that system.

0:08:35.4 AS: Yeah, and I'm thinking about even when I recently did like a fast and my weight went down, and I had it down for a little while, and then I went back to eating, of course, and then all of a sudden you've realized there's this rebound and now that you're back, and now I'm back up to where I was and it's stable. It's not what where I really want it to be, but it's stable. And so you realize like there's a...as you're saying, people can't deal with chaos every day, so it stabilizes at some point, but that point may be far from the optimum of what that system could produce or something like that, I guess.

0:09:13.4 DL: Well, that's a good example, 'cause the person says he understands the stable system. Well, before you started to do that fast and actually track your weight, you were probably...your weight was probably in a normal range. That's the way it is for me. If I don't track it at all, it's usually within five or six pounds, given what's going on over a long period of time. But as soon as I track it and I start to understand what's happening and I see what the average weight is, then I have to think about, okay, am I happy with the average? So, again, this is back to the stable system. I always tell teachers, if you're happy with your average and you know it, clap your hands.

[laughter]

0:10:00.8 AS: If you're happy with your average, and you know it, clap your hands. [singing]

0:10:03.4 DL: And you know it, clap your hands. Yeah.

0:10:06.7 AS: There you go.

0:10:06.8 DL: So yeah. And they all laugh and everything else, but how do you know if you're happy with your average? Well, you're gonna have to collect some data. So it really doesn't matter what system you're thinking about managing, you have to understand...do you understand a the stable system? So let's say that: "Well, these kids today, they're always late to class." Okay, well, set up a run chart, track that for 12 days or 20 days, and find out what you're talking about. Find out. Are all the kids late to class? "Well, no, they're...no, they're not all late to class." Well, okay, well how many are late to class and what's happening with the data over time?

0:10:46.7 DL: So you have to figure it out what's important to you and how you're gonna go about that. The example I often give is, I worked with a middle school principal and he said, "Oh well, the teachers are complaining that the buses are always late." And I said: "Okay, well, that's pretty easy to t
