Mike Rother: The Toyota Kata Practice Guide

When I landed in Detroit last week to visit Menlo Innovations, Mike Rother picked me up at the airport. As soon as I settled in to the passenger’s seat, he handed me my long-anticipated copy of his new book The Toyota Kata Practice Guide. That is the first disclaimer here. The second disclaimer is that last winter he asked if I would do him a favor and take a look through the manuscript with a red pencil. Um… YEAH!

Thus, I can’t say this post is an unbiased book review. Quite the opposite.

What I am going to do here is go through the book and alternately share two things:

  1. Why I think this is a great read for anyone, no matter your skill level or experience with Toyota Kata.
  2. Reflections on my own experience that may have been amplified as I went through it.

The other caveat I really have to offer is this: I have the hard copy of the book. I am absolutely referring to it for the content I am citing. That being said, I drew a lot of the deeper insights I am reporting when I was parsing the manuscript. That was much more than “reading” as I had to really think about what the author is trying to say rather than just read it. If you are serious about learning, I suggest you take your time as you, too, go through the book. Don’t just read. Parse.

And a final disclosure: if you click on the links mentioning the books, it will take you to the Amazon.com page. If you choose to buy the book, I get small affiliate kickback that doesn’t affect the price you pay.

A Bit of History: Toyota Kata has Evolved

From my perspective, I think Toyota Kata as a topic has evolved quite a bit since the original book was published in 2009. The Practice Guide reflects what we, as a community, have learned since then.

As I see it, that evolution has taken two tracks.

1. More Sophistication

imageOn the one hand, the practice has become more sophisticated as people explore and learn application in contexts other than the original industrial examples. Mike Rother and Gerd Aulinger published Toyota Kata Culture early this year. That book provides working examples of vertical linkage between organizational strategy and shop floor improvement efforts. Most of the presenters at Lean Frontier’s recent online Kata Practitioner Day were describing their experiences applying what was outlined in that book. Last year’s KataCon featured a number of presenters who have adapted the routines to their specific situations, and we have seen the Kata morph as they are used “in the wild.” This is all OK so long as the fundamentals are practiced and well understood prior to making alterations – which brings us to the second point.

2. Better Focus on Kata as Fundamentals

The other evolution has been a better insight that the Improvement Kata and Coaching Kata are, in Mike Rother’s words, Starter Kata. They aren’t something you implement. They are routines to practice as you develop the underlying skill.

If you go to a Toyota, or a Menlo Innovations, you won’t see them using Toyota Kata. They don’t have to because the routines that the Kata are designed to teach are already embedded in “the way we do things” in organizations like that.

We use the Improvement Kata and Coaching Kata to learn so that, at some point in the future, we too can create a culture where the underlying thinking is embedded in “the way we do things.” You don’t have to think about it, because it is a habit.

Rather than being a fairly high-level summary of the research findings (as the original book was), the Practice Guide is what the title suggests: A step-by-step guide of how to practice and what to practice.

The Toyota Kata Practice Guide

With all of that as background, let’s dig into the book.

The book is divided into three discrete sections. I’m going to go through the book pretty much in order, with the section and chapter titles as headers.

Part 1: Bringing Together Scientific Thinking and Practice

The first part of the book is really an executive summary of sorts. It is an excellent read for a manager or executive who wants better understanding of what this “Toyota Kata” thing you (my reader here) might be advocating. It sets out the fundamental “Why, what and how” without bogging down in tons of detail.

Scientific Thinking for Everyone

This is the “Why”  and “What.”

In the first chapter Mike Rother makes the case that “scientific thinking” is the meta-skill or habit that found in most (if not all) learning and high-performance organizations. I agree with him. I believe organizations with an innate ability to reflexively apply good scientific thinking are the ones who can readily adapt to changes in their environment. Those who cannot are the ones who keep doing the same things in the face of evidence that screams “Change!”

The next key point is that “scientific thinking” is not the default habit of the vast majority of adult humans – for lots of good reasons leading to our survival as a species. It is a learned skill.

Learning a skill requires practice, plus knowing what and how to practice. The Improvement Kata provides a pattern for practice as well as initial routines to follow in order to get the fundamentals.

And that point is what separates the Practice Guide from the vast majority of business books. Most business books speak in general terms about principles to apply, and ways you should think differently. They are saying that “you need to develop different habits,” and even telling you what those habits should be, but come up short on telling you how to change your existing habits to those new habits.

Thus if you, the reader of the book, are willing to say “I want to learn this thinking pattern,” as well as say “… and I am willing to work at it and make mistakes in order to learn,” then this book is for you. Otherwise, it probably isn’t. That’s OK.

For the rest of you, read on.

Chapters 2, 3 and 4 go into increasing depth on the process of “deliberate practice” how the structure of the Improvement Kata and Coaching Kata supports it.

Part 2: Practice Routines for the Learner (The Improvement Kata)

At a high level the “Improvement Kata” is expressed as a four step process that maps to pretty much any process of learning, discovery or problem solving that works.

image

In this section, there is a chapter for each of the steps above that sets out, in detail:

  • The higher level purpose of the step – the “why?”
  • The discrete steps you should practice, including detailed “How to” instructions as step-by-step Starter Kata that a learner should follow precisely while he is grounding on the basics.

I believe it is equally important for new coaches to work hard to keep their learners focused on the Starter Kata as well – you are both in learning mode. (More about coaches in the next section.)

I do, though, want to discuss the one step where I can see people having the biggest struggle mapping the explicit Starter Kata to their own situation: Grasp the current condition.

The Starter Kata steps for Grasping the Current Condition are explicit and detailed. At a high level they are:

1. Graph the Process Outcome Performance

2. Calculate the Customer Demand Rate and Planned Cycle Time

3. Study the Process’s Operating Patterns

4. Check Equipment Capacity

5. Calculate the Core Work Content

The book devotes several pages to how to carry out each of these steps. However, the examples given in the book, and the way it is usually taught, use the context of industrial production processes. This makes sense. Industry is (1) the origin of the entire body of thought and (2) the world the vast majority of practitioners live in.

But we legitimately get push-back from people who live in a world outside of industry. What I have found, though, is when we work hard to figure it out, we can usually find solid analogies where the Starter Kata do apply to practically any non-industrial process where people are trying to get something done.

Often the mapping isn’t obvious because people in non-linear work are less aware of the repeating patterns they have. Or they live in worlds where the disruptions are continuous, and though a cadence is intended, it seems to be impossible to achieve. However, if you are legitimately making an effort, and having trouble figuring out how to apply the Starter Kata outlined in the book to your own experience, here is an offer: Get in touch. Let’s talk and see if we can figure it out together.

A Little More about Starter Kata

The concept of “Starter Kata” is new since the publication of the original book. Actually it isn’t really new, just much more explicit now.

When we see working examples, such as in books about A3 Problem Solving, we are often looking at the work of people who are unconsciously competent, if not masters, of doing this.

To someone trying to learn it, though, all of these “different approaches” can be confusing if they are trying to just understand what they should do. A coach trying to help by giving them a lot of general guidelines as decision criteria often isn’t helping much to clarify the confusion. (And may well be adding to the frustration.)

The point of a “Starter Kata” is to provide a high level of structure that can guide the learner until she “gets” the higher level purpose. In traditional east-Asian martial arts, this higher purpose is often left unspoken, with the intent that the learner will reflect and come to deeper understanding.*

In the Practice Guide Mike is much more clear about the underlying “why” of the emphasis on initial rote practice. We, the readers, are in Stage 1 in this illustration:

If you are trying to understand what Toyota Kata is about, or you are trying to up your own skills for process improvement or problem solving, then read the steps that are set out in the book and follow them exactly as they are written to the best of your ability. Do this even (especially!) if they don’t seem 100% appropriate to the problem you are trying to solve.

“But I’m not a beginner” you might say.

Let me issue this personal challenge: Pretend you are a beginner. All of us can learn from going back and applying the basics. You may well discover:

  • Additional insights about things you are already doing. (Which I did.)
  • Some approaches that are simpler and more effective than what you have evolved over the years. (Which I did.)
  • More comfort with using these Starter Kata as a teaching guide for others. (Which I have.)

Although this material on the Improvement Kata has been “out in the wild” for some time, I think I can honestly say that The Toyota Kata Practice Guide is a vastly better expression than I have seen anywhere else – including earlier material from Mike Rother – and my own previous material for that matter. (I started making changes to my own materials based on my early look at the manuscript.)

Part 3: Practice Routines for the Coach (The Coaching Kata)

This is the new and exciting part.

While there has been a fair amount about the Improvement Kata out there for a while, the only things we have had about coaching have been the “5 Questions,” a few YouTube videos and some general principles. I’ve tried on this site to relate my own experiences as I learned, but The Toyota Kata Practice Guide is, in my view, the first truly comprehensive reference that wraps up everything we knew up to this point in a single reference.

Tangent: Learn to Play Before You Coach

Though this is part of the message in the book, what follows are my own experiences and interpretations.

Nearly all managers want to jump right into coaching. They see the “5 Questions” and some of them think that is all there is to it – just ask those questions and we’re good. Actually, that’s kind of OK so long as you realize that you are probably making mistakes, and are consciously and deliberately reflecting on what those mistakes might be. But that reflection is often what doesn’t happen – people tend to presume competence, and don’t challenge their own role if they see learners struggling. It is a lot easier for me to blame the learner, or to say “this kata thing doesn’t work” than it is to question my own competence.

Until you have struggled as a learner to apply the Improvement Kata (using the Starter Kata) on a real problem (not just a classroom exercise) that affects the work of real people and the outcomes to real customers, please don’t just pick up the 5 Questions card and think you are a coach.

Coaching Starter Kata

If you truly understand the Improvement Kata, and then go to a Toyota, or other company that has a solid practice for continuous improvement, you will readily see the underlying patterns for problem solving and improvement. Coaching, though, is a bit more abstract – harder to pin down into discrete steps.

Read John Shook’s excellent book Managing to Learn (and I highly recommended it as a complement to The Toyota Kata Practice Guide), and you will get a good feel for the Toyota-style coaching dialog. You won’t read “the 5 Questions” in that book, nor will you see the repetitive nature of the coaching cycles that are the signature hallmark of Toyota Kata.

Here’s why:

There are a couple of ways to learn that master-level coaching. One is to work your entire career in an organization that inherently thinks and talks this way. If you do, you will pick it up naturally “as the way we do things” and won’t give it another thought. Human beings are good at that – its social integration into a group.

Imagine, if you would, growing up in a community where everyone was a musician. Thinking in the structure of music would be innate, you wouldn’t even be aware you were doing it. Growing up, you would learn to play instruments, to sing, to compose, to arrange music because that is what everyone around you was doing. That is also how we learn the nuance of language. We can see throughout history how mastery in arts tends to run in families. This is why.

And that is how the coaching character in Managing to Learn gained his skill.

But if you want to learn music, or another language, or some other skill, when you aren’t immersed in it all day, then you have to learn it differently. You have to deliberately practice, and ideally practice with the guidance of someone who not only has the skill you are trying to learn but also has the skill to teach others. (Which is different.)

The question Mike Rother was trying to answer with his original research was “How can the rest of us learn to think and coach like that?” – when we don’t live in that environment every day. In those cases we have to be overt and deliberate.

The real contribution that Mike has made to this community is to turn “coaching” from a “you know it when you see it” innate skill into a routine we can practice to learn how to do it. I can’t emphasize that enough.

And, although the Coaching Kata is taught within a specific domain of process improvement, the underlying questions are the basis for anything people are working to achieve. Cognitive Based Therapy, for example, is structured exactly the same way.**

OK – with all of those rambling thoughts aside, let’s dig back into the book.

As in the previous section, we begin with an introduction section that gives an overview of what coaching is actually all about.

Then the following chapters successively break down the coaching cycle into finer and finer detail.

Coaching Cycles: Concept Overview

This chapter emphasizes the cadence of coaching cycles, the importance of frequent practice (for both the coach and the learner), and the purpose and structure of the “5 Questions.”

A key point that bears emphasizing here is that the purpose of coaching is to advance the learner’s knowledge, both of the process being addressed and the “art of scientific thinking.” Thus, the reason the coach asks the questions is to learn where the boundary is between what the learner knows, and what the learner doesn’t know.

Often the learner himself isn’t aware of that boundary. Again, it is human nature to fill in the narrative, complete the story, and create meaning – jump to conclusions even with limited evidence. By asking for specifics, and by gently asking for evidence – “How do you know?” types of questions, the coach learns that point where the learner moves beyond objective facts and into speculating. (Or, ideally, says “I don’t understand” or “I don’t know” about something that needs to be understood or known.) The “next step or experiment” should be a step that pushes that threshold of knowledge boundary out a little further.

In the book, we get an example coaching dialog, and some warnings and cautions about commonly ingrained habits we probably all have to “give the answers” rather than “ask the questions.”

This chapter wraps up with some advice about when (and why) you (as a coach) might need to let go of the formal structure if a learner is struggling with it.

How To Do a Coaching Cycle: Practice Routines

After the overview, Mike gets down to what to do, how do give good corrective feedback, and keep the learner in the game psychologically.

He then gives us a detailed example coaching dialog, and afterwards, puts us into the role of the 2nd Coach, challenging the reader to predict what feedback the 2nd coach should give before reading what actually happens.

The dialog is followed by what I think is the most powerful part of the book as he guides us through each of the “5 Questions.” For each one, we get a description of why that question is important, its purpose, followed by:

  • Key Points – Advice that reflects feedback and helpful tips gained over the years from the entire community.
  • Clarifying Questions – Possible follow-on questions that can help the coach clarify what the learner is intending and thinking.
  • Potential Weak Points – Things to specifically look for that can help the learner construct better logical connections and experiments.

This chapter, in my view, is alone worth the price of the book. Everything else is bonus material.

Conclusion

This post took me quite a bit longer to write than I predicted it would, and I’ll judge that it is still rougher than I would like. But I am going to suppress my inner perfectionist and put it out there.

Anyone who knows me is aware that, even before it was published, I have made no secret about touting this book to anyone who is interested in continuous improvement.

In the end, though, this book is asking you to actually do some work. People who are looking for easy answers aren’t going to find them here. But then, I really don’t think easy answers can be found anywhere if we are honest with ourselves.

As I said about the original book back in 2010, I would really like to find copies of The Toyota Kata Practice Guide on the desk of every line leader I encounter. I want to see the books with sticky notes all over them, annotated, highlighted. The likely reality is that the primary readers will be the tens of thousands of staff practitioners who make up the bulk of the people who are reading this (you aren’t alone).

If you are one of those practitioners, YOUR challenge is to learn to teach by the methods outlined here, and then learn to apply them as you coach upward and laterally to the leaders of your respective organizations. Those conversations may have different words, but the basis is still the same: to help leaders break down the challenges they face into manageable chunks and tackle the problems and obstacles one-by-one.

One Final Note:

The overall theme for the 2018 KataCon is practice – keying off of the release of this book. Come join us, share your experiences, and meet Mike Rother, Rich Sheridan, and other leaders in this awesome community.

——–

*Those of us who were taught by Japanese sensei, such as Shingijutsu (especially the first generation such as Iwata, Nakao, Niwa) were expected to follow their instructions (“Don’t ask Why?… Say “Hai!”). It was implied, but never stated, that we should reflect on the higher-level meaning. Over the years, I have seen a fair number of practitioners get better and better at knowing what instructions would be appropriate in a specific case, but never really understand the higher-level meanings or purpose behind those tools. Thus, they end up as competent, but mechanistic, practitioners.

**Note: Mastering the Coaching Kata will not make you a therapist, though it may help you empathetically help a friend in need.

Toyota Kata and The Menlo Way

I have been telling everyone who will listen to read Rich Sheridan’s book Joy, Inc. ever since I came across and read it in the fall of 2015.

Fast forward to earlier this year when Lean Frontiers sent out their request for suggested keynote speakers for KataCon. I wrote to Mike Rother and asked him “Do you think we could get Rich Sheridan?”

Skip ahead a bit more, and I spent four days last week at Menlo Innovations in Ann Arbor – two days “in the chalk circle” paying close attention to the actual day-to-day work there, and two days working (pairing) with Rich Sheridan to work out the key beats for his KataCon keynote.

 

The “So What?” Test

Menlo is well known as a benchmark for a great working culture. But the question you may be asking (and, honestly I hope you ARE asking it) is “What does Menlo Innovations and agile software development have to do with Toyota Kata?”

If you visit Menlo (and I really hope you do!) here is what you won’t see:

  • Learner storyboards.
  • “5 Questions” coaching cycles.
  • Obstacle parking lots.
  • Experiment Records (PDCA Records)

In other words, you won’t see the explicit artifacts that characterize an organization using Toyota Kata to learn how to think about improvement scientifically. In that sense, Menlo isn’t a “Toyota Kata” benchmark.

OK… and?

You don’t see those things at Toyota either. You don’t go to Toyota to see “Toyota Kata.”

The Underlying Thinking Pattern

What you will see (and hear… if you pay attention) at Menlo Innovations is an underlying pattern of scientific thinking and safe problem solving in everything they do.

Let’s review what Toyota Kata is really all about.

Rather than re-writing something elegant here, I am going to quote from my part of an email exchange between Mike Rother, Rich Sheridan and me:

Going back to Mike’s original research premise, we knew that Toyota has this pretty awesome culture thing, but didn’t really understand the “secret sauce” of the exact structure of their interactions. Put another way, we saw and understood all of the artifacts, but copying the artifacts doesn’t copy the culture.

Mike’s research was really the first that dug deeper into the interactions that the artifacts support.

Once he extracted that “secret sauce” he then boiled off all of the other stuff, and what remained at the bottom of the pot was the Improvement Kata steps and the Coaching Kata steps.

In practice at Toyota, those things are deeply embedded in the artifacts. Sometimes they aren’t even spoken.

My informal hypothesis was that if I spent time paying attention to, not just the artifacts, but the way those artifacts guided interactions at Menlo, and then boiled off the other stuff, what would remain at the bottom of the Menlo pot would also be the Improvement Kata and Coaching Kata steps. And, though I didn’t do this formally, and yes, I had confirmation bias working here, I believe I can safely say “I have no evidence to contradict this hypothesis.”

For example:

In our conversation on Friday, Mike pushed back a bit on “just run the experiment,” [context clarification: Experiments to randomly try stuff, without a clear target condition rarely get you anywhere] but the reality I observed and heard was that “purpose” (challenge and direction) and “current condition” are deeply embedded in the day-to-day interactions, and “just run the experiment” is, indeed, working on a specific obstacle in the way of a target condition of some kind.

[…]

“What problem are you trying to solve?” is Menlo jargon that I overheard many times just listening to people talk.

Within Menlo, that term is contextual. Sometimes it is about the higher-level direction and challenge.

Sometimes it is about an intermediate target condition.

Sometimes it is about an immediate problem or obstacle.

As we say in Kata world, it is fractal. It is truly fractal at Menlo as well, to the point where the words don’t change at various levels.

The words DO change at various levels in Toyota Kata’s jargon, but we can’t get hung up on the terms, we have to look at the structure of problem solving.

Menlo’s co-founders already had this thinking pattern, and deliberately sought to embed it into the culture of the company they were starting. There wasn’t really any need to explicitly teach it because they weren’t trying to change the default behavior of an organization. New Menlonians learn the culture through the interviewing and on-boarding process and adopt very quickly because the very structure of the work environment drives the culture there.

In fact, spend any time there even just hanging out, and it is very difficult NOT to get pulled into The Menlo Way. Like everyone else, Rich and I were in the daily stand-up as pair-partners, reporting our work progress on his keynote.

What About Toyota Kata?

Menlo has had hundreds (thousands, actually) of visitors, and those who are “lean savvy” all ask if Menlo is “using lean” as their guideline. The answer is “no, we are just trying to solve problems.” While they have certainly incorporated most of the artifacts of “agile software production,” the purists push back that they aren’t “really doing it” because they didn’t copy those artifacts exactly. Nope. They used them as a baseline to solve Menlo’s problems.

When we see an awesome problem-solving culture, it is tempting to try to reverse engineer it by copying the physical mechanics, such as heijunka boxes (work authorization boards), kanban, “standard work” and the like.

But we have to dig down and look at the routines, the behavior that those artifacts and rituals support. When we do, we see the same patterns that Toyota Kata is intended to teach.

You need to begin with the thinking pattern. Use Toyota Kata to learn that.

As you do, take a look at your artifacts – the procedures, the policies, the control mechanics of your work. Reinforce the ones that are working to create the kind of culture you want. Challenge the ones that are getting in your way. Do both of those things as deliberate experiments toward a clear vision of the culture you want to create.

That is the benefit of studying companies like Menlo.

I hope to see you all at KataCon, hear what Rich has to say to our community, and establish a link between these two communities that have, up to now, been separate.

Only Action Reveals What Must Be Done

I am reading Story by Robert McKee (because the structure of stories interests me). There is a profound passage which totally resonates with everything we discuss here.

Every human being acts, from one moment to the next, knowingly or unknowingly, on his sense of probability, on what he expects, in all likelihood, to happen when he takes an action. We all walk this earth thinking, or at least hoping, that we understand ourselves, our intimates, society, and the world. We behave according to what we believe to be the truth of ourselves, the people around us, and the environment. But this truth we cannot know absolutely. It’s what we believe to be true.

We also believe we’re free to make any decision whatsoever to take any action whatsoever. But every choice and action we make and take, spontaneous or deliberate, is rooted in the sum total of our experience, in what has happened to us in actuality, imagination, or dream to that moment. We then choose to act based on what this gathering of life tells us will be the probable reaction from our world. It is only then, when we take action, that we discover necessity.

Necessity is absolute truth. Necessity is what in fact happens when we act. This truth is known — and can only be known — when we take action into the depth and breadth of our world and have its reaction. This reaction is the truth of our existence at that precise moment, no matter what we believed the moment before. Necessity is what must and does actually happen, as opposed to probability, which is what we hope or expect to happen.

As in life, so in fiction.

In other words, the best we can do is make a prediction. We will not, we cannot, know for certain what will actually happen until it does. The choice we make in that moment to either learn from this experience, or disregard it, is what decides the course from that point.

We are all protagonists in our own lives.

Overproduction vs. Fast Improvement Cycles

A couple of weeks ago ago I posted the question “Are you overproducing improvements?” and compared a typical improvement “blitz” with a large monument machine that produces in large batches.

I’d like to dive a little deeper into some of the paradoxes and implications of 1:1 flow of anything, improvements included.

What is “overproduction” – really?

In the classic “7 wastes” context, overproduction is making something faster than your customer needs it. In practical terms, this means that the cycle time of the producing process is faster than the cycle time of the consuming process, and the producing process keeps making output after a queue has built up above a predetermined “stop point.”

If the cycle times are matched, then as an item is completed by the upstream process, it is consumed by the downstream process.

If the upstream process is cycling faster, then there must be an accumulation of WIP in the middle, and that accumulation must be dealt with. Further, those accumulated items are not yet verified as fit-for-use by the downstream process that uses them.

The way this applies to my “Big Improvement Machine” metaphor is that we are generating “improvement ideas” faster than we can test and incorporate them into the process.

“Small Changes” Doesn’t Mean “Slow Changes”

No matter how good your solution or idea, it is just an academic exercise until it is anchored as the an organizational norm. The rate limit on improvement is established by how quickly people can absorb changes to their daily, habitual routine.

Implementing and testing small changes one-by-one is generally faster than trying to make One Big Change all at once. When we do One Big Change, it is usually actually a lot of small changes.

I hear “we don’t have time to experiment,” but when I ask what really happens if a big change is made, what I hear almost every time is they had to spend considerable time getting things working. Why? Because no matter how well the Big Change was thought through, once you are actually trying it, the REAL problems will come up.

Key Point #1: Don’t waste time trying to develop paper solutions to every problem you can imagine. Instead, “go real” with enough of the new process to start revealing the real issues as quickly as possible.

In other words, the sooner you start actively learning vs. trying to design perfection, the quicker you’ll get something working.

Slow is Smooth, Smooth is Fast

Your other objective here is to develop the skill within the organization to test and anchor changes quickly, as a matter of routine. This will take time.

When we see a high-performance organization making rapid big changes, what we are typically seeing is making small changes even more rapidly. They have learned, through practice over time, how to do this. It isn’t reasonable to expect any organization to immediately know how to do this.

Key Point #2: If managers, or professional change agents (internal or external consultants, for example) are telling people exactly what to do, this learning is not taking place.

It is critical for the organization to develop this learning skill, and they are only going to do it if they can practice. Learning something new always involves doing it slowly, and poorly at first. If your internal or external consultants are serving you, their primary focus is on developing this basic competence. Their secondary focus is on getting the changes into place. This is the only approach that actually strengthens the organization’s capability.

The same is true for an operational manager who “gets” lean, but tries to just direct people to implement the perfect flow. It will work pretty well for a while. But think about how you (the operational manager) learned this stuff: Likely you learned it by making mistakes and figuring things out. If you don’t give your people a chance learn for themselves, you limit the organization in two ways:

  1. They will never be any better than you.
  2. They will wait to do what they are told, because that is what you are teaching them to do.

Think about what you want your people to be capable of doing without your help, and make sure you are giving them direction that requires them to practice doing those things. It will likely be different than telling them what they layout should look like.

Improve your Cycle Time for Change

Coming back to the original metaphor, if you want fast changes to last, you have to work speeding up the organization’s cycle time for testing improvement ideas. Part of this is going to involve making that activity an inherent and deliberate part of the daily work, not a special exception to daily work.

Part of that is going to be paying attention to how people are working on testing their ideas. The Improvement Kata and Coaching Kata are one way to learn how to deliberately structure this work so that learning takes place. Like any exponential curve, progress seems painfully slow at first. Don’t let that fool you. Be patient, do this right, and the organization will slingshot itself past where you would be with a liner approach.

Small changes, applied smoothly and continuously become big changes very quickly.

Heavy Equipment Overhaul: Flow at Takt in 1938!

This is a great contemporary film from 1938 describing the complete overhaul of a mainline 4-6-0 steam locomotive in the U.K.

What is interesting (to me) is:

  • The overhaul involves stripping the locomotive down to individual parts. Each of the parts, in turn, flows through a process of inspection / repair or replacement, with a strict timing to ensure it is delivered back to re-assembly when required.
  • There are 6 positions with a takt time of 10 hours 44 minutes. Everything is timed to this cadence.
  • I can only speculate, but with that degree of rigor in the timing, they are going to be able to see a delay or problem very quickly, and get out in front of it before it causes a delay in the main-line work.
  • The parts that come off are not necessarily the exact once that are put back on. Everything is flowing – there are multiple locomotives in overhaul.

More thoughts below the video.

(Here is a direct YouTube link for those who don’t get the embed in the email subscription: https://www.youtube.com/watch?v=ktHw1wR9XOU)

Flow in Overhaul and Repair

This is a great working example of a process flow that proves difficult for some organizations: Overhaul and repair. “We don’t know what we will find, so there is no way we can sequence and index it on a timetable.”

I’ve seen a similar operation overhauling helicopters. The intended flow was exactly the same.

  • Like the locomotive flow, they stripped everything down to the airframe. The various components had different flow paths for sheet metal, hydraulic components, power-train (engine / transmission), rotor components, electrical, avionics, and composite parts.
  • The objective was to deliver “good as new” items on time back to the re-assembly process.

Here is where they ran into problems:

  • If an item needed repair, then the repairs were done, and the item flowed back.
  • But if an item could not be repaired (needed to be scrapped and replaced) it was tagged, and returned to the “customer” – the parts bin in main assembly. It arrived just like any other part except this one was tagged as unusable. It was up to the assembly supervisor to notice, and initiate ordering a new one.

Who is your customer? What do they need?

The breakdown was that the repair line(s) saw themselves as providing a repair service. If it couldn’t be repaired, sorry.

What their customer needed was a good part to install on the helicopter. If they can create a good part by repairing the old one, great. But if it isn’t repairable, their customer still needs a good one and they need it on time.

The Importance of Timing and Sequencing

In the locomotive video, they emphasize the precise timing and sequencing to make sure each part arrives in the proper sequence, when it is needed, where it is needed.

Even if it actually worked like they describe, I can be sure it didn’t work like that when they first started.

The timing and sequencing is a hypothesis. Each time they overhaul a locomotive, in fact each individual part flow, is an experiment to test that hypothesis. Over time, it is possible to dial things in very precisely.

Why? So you can quickly identify those truly anomalous conditions that demand your intervention.

Normal vs Abnormal

Just because there are frequent issues does not negate the fact that most of the time things can probably flow pretty well. What we tend to do, however, is focus on the problem cases and give up on all of them. “What about this? What about that?” bringing up the legitimate issues and problems, causes us to lose sight of the fact that underneath it all there is a baseline pattern.

What is important is to define the point at which we need to intervene, and set up the process to detect that point. When we can clearly distinguish between routine work and true exceptions, and not try to treat everything as a special case.

Are You Overproducing Improvements?

Imagine a factory with a large monument machine. It takes several days to set up. When it does run, it runs very fast, much faster than you can actually use its output. Therefore, you take the excess output and store it to use later. Actually, you don’t know how many items you need to make, so you make as many as you can while the machine is available to you.

image

Some of that excess output may prove to be less useful than you thought, but there is pressure to use it all anyway since it was so expensive to produce.

After a run making items for one process, you change it over to make items for a different process, and build up a queue of output there.

When all of the output is used, it all may or may not work the way you expected it to.

Most of us would see this as a classic case of “overproduction” – overwhelming the system with excess output that hasn’t been checked for quality, that isn’t needed right now, and might or might not be useful in the future. But it seemed like good efficiency to make it while we could.

Our lean thinking tells us we want to do a few things here. Ultimately, we want to work hard to break up the batches, and make the value flow more evenly to each of the customer processes, and ultimately to the end customers. The work we must do to keep things moving smoothly and evenly will pay off in both tangible and intangible ways.

One of the primary reasons we push hard for 1:1 flow in the lean world is to enable one-by-one confirmation.

We want to test each item of output to confirm that it actually performs as expected rather than making lots of them without knowing if they are any good.

How Do You Produce Improvements?

Now, imagine doing improvements this way. What would it look like?

A process would be scheduled to receive the rapid output of the Improvement Machine.

The Improvement Machine would be set up over a period of several days to produce improvements for the target process.

Once it was running, we would run the Improvement Machine very fast for a week or so. It would produce improvements faster than the target process can really absorb them.

At the end of the run, we might test the improvements as a batch. We might not test them at all, but rather report that they have been implemented with the assumption that they will work. We would also have excess improvements stored on a to-do list for future use.

Those excess improvements might, or might not, prove to be useful, but we would have huge pressure to implement them because they are on the list.

Once the machine was done producing improvements for one process, it would be set up to produce improvements the same way for another.

We would measure how many times we were able to run the improvement machine in a year, not so much the actual sustained impact we were making.

Improvements that were made without the machine might not be measured or credited at all. Or worse, these rogue improvements might actually be discouraged since they are made by people who aren’t certified to run the machine.

Now… substitute “kaizen event” for “improvement machine” and see if it makes any sense.

Why Are Big Batches Necessary?

The reason the Large Monument Machine has to cycle batches of output to different customers is because those customer processes don’t have the internal capability to do what it does. We need an outside resource to do it.

The countermeasure we strive to apply in these cases is to identify the capability that the customer process does need. We then work hard to develop it on a scale they can incorporate into their daily work. This is typically smaller, more specialized, and scoped to their needs.

My purpose here, though, is to apply a metaphor, not to discuss the economics of large capital equipment.

When we “batch improvements” it is often for the same reason: The area that is being improved can’t do it themselves, so we have to dedicate a scarce outside resource – an improvement expert – to lead them through it. Since that improvement leader can’t be there 100% of the time, he has to work as hard and fast as he can when he IS there.

Making Improvements vs. Teaching How to Make Improvements

The countermeasure in both scenarios is the same: Develop the capability within the process. In the case of making improvements, this means asking ourselves “Why can’t they do it?”

All of these are harder than just doing it for them. But if we want improvement to flow, this is the work that must be done.

The Ecosystem of Culture

image

An organization’s culture and mindset evolve over time. When confronted with a problem or challenge, the organization (or more accurately, the people in the organization) view it through a filter of their experiences. Ideas that they believe have worked for them under past similar conditions are more likely to be applied again. Ideas that have seemed less successful, or more difficult, in the past are less likely to be applied again.

Over time, this collective experience determines how they respond to the day to day rough spots as well as more serious challenges. Those unconscious biases drive the responses, and in turn, shape how their processes are structured.

Different Cultures = Different Ecosystems

The process mechanics in a company like Toyota evolved over decades in a very specific organizational culture ecosystem, with specific values and beliefs shaped by their historic experiences.

When we are looking at the current processes in a different company, we are seeing the process mechanics that evolved in their management culture. Those process mechanics are optimized by the pressures that are exerted by the way THAT company is managed. Since Toyota is managed differently, its processes are optimized by different pressures, so will look different.

If we take Toyota’s process mechanics and shift them into a different ecosystem, they will have the different pressures exerted upon them. Different default decisions will be made. These alien process mechanics will likely begin to resemble the legacy processes rather quickly, if they survive at all.

This is why the promise of a rapid and dramatic change in operational results is frequently unfulfilled. The process mechanics are imported from a tropical rain forest, and installed in an alpine meadow. As beautiful as it looks in one environment, it won’t stand for long in the other.

image

Adjusting the Culture vs. Adjusting the Process Mechanics

If we want this transplant to work, we have to pay careful attention to those evolutionary pressures. In practical terms, this means we try the new mechanics, we must watch carefully to learn what problems they reveal. We also need to observe the decisions that are made when these problems come up.

What adjustments need to be made in the way people interact, and to the immediate response to problems or surprises if this new process is to thrive?

Having a formal structure for this deliberate self-reflection is critical.

The Improvement Kata is engineered to specifically drive this kind of reflection by making changes as experiments, then deliberately reflecting with the question “What have we learned?”

For this to work, of course, we must be honest with ourselves and not just issue a flip answer like “It doesn’t work.”

Because we are asking people to adjust their responses, we are asking them to do things which are unfamiliar and may well run opposite from what they have experienced as successful for them in the past. If we try to move too fast, we are asking them to trust an alien process which is, in their experience, unproven in their environment. We might be asking them to reveal their own limits of knowledge – which is very scary for most of us.

That, in turn, asks for reflection on why “I don’t know…” is so scary to admit in the organization’s culture.

We have sold “lean” as a deceptively simple set of common-sense process mechanics with the idea that if we just implement them, we’ll get incredibly great results. As true as that is, “just implement them” is a lot harder than most of the “rapid improvement” models imply.

There is a lot going on behind what appears to be well understood and simple on the surface.

Executive Rounding: Taking the Organization’s Vitals

Background:

image

I wrote an article appearing in the current (October 2017) issue of AME Target Magazine (page 20) that profiles two very different organizations that have both seen really positive shifts in their culture. (And yes, my wife pointed out the misspelling “continous” on the magazine cover.)

The second case study was about Meritus Health in Hagerstown, Maryland, and I want to go into a little more depth here about an element that has, so far, been a keystone to the positive changes they are seeing.

Sara Abshari and Eileen Jaskuta are presenting the Meritus story at the AME conference next week (October 9, 2017).

Sara is a manager (and excellent kata coach) in the Meritus CI office. Eileen is now at Main Line Health System, but was the Chief Quality Officer at Meritus at the time Joe was presenting at KataCon.

Their presentation is titled Death From Kaizen to Daily Improvement and outlines the journey at Meritus, including the development of executive rounding. If you are attending the conference, I encourage you to seek them out – as well as Craig Stritar – and talk to them about their experiences.

Mark’s Word Quibble

In addition, honestly, the Target Magazine editors made a single-word change in the article that I feel substantially changed the contextual meaning of the paragraph, and I am using this forum to explain the significance.

Here is paragraph from the draft as originally submitted. (Highlighting added to point out the difference):

[…][Meritus][…] executives follow a similar structure as they round several times a week to check-in with the front line and ensure there are no obstacles to making progress. Like the Managing Daily improvement meetings at Idex, the executive rounding at Meritus has evolved as they have learned how to connect the front-line improvements to the strategic priorities.

This is what appears in print in the magazine:

[…][Meritus][…] executives follow a similar structure as they visit several times a week to check in with the frontline and ensure there are no obstacles to making progress. Like the MDI meetings at Idex, the executive visiting at Meritus has evolved as they have learned how to connect the front-line improvements to the strategic priorities.

While this editing quibble can easily be dismissed as a pedantic author (me), the positive here is it gives me an opportunity to highlight different meanings in context, go into more depth on the back-story than I could in the magazine article, and invite those of you who will be attending the upcoming AME conference to talk to some of the key people who will be presenting their story there.

Rounding vs. Visiting

In the world of healthcare, “rounding” is the standard work performed by nurses and physicians as they check on the status of each patient. During rounds, they should be deliberately comparing key metrics and indicators of the patient’s health (vital signs, etc.) against what is expected. If something is out of the expected range, that becomes a signal for further investigation or intervention.

“Visiting” is what the patient’s family and friends do. They stop by, and engage socially.

In industry, we talk about “gemba walks,” and if they are done well, they serve the same purpose as “rounding” on patients in healthcare. A gemba walk should be standard work that determines if things are operating normally, and if they are not, investigating further or intervening in some way.

I am speculating that if I had used the term “structured leader standard work” rather than “rounding” it would not have been changed to “visiting.”

Executive Rounding

Joe Ross, the CEO at Meritus Health, presented a keynote at the Kata Summit last February (2017). You can actually download a copy of his presentation here: http://katasummit.com/2017presentations/. The title of his presentation was “Creating Healthy Disruption with Kata.” More about that in a bit.

The keystone of his presentation was about the executives doing structured rounding on various departments several times a week. These are the C-Level executives, and senior Vice Presidents. They round in teams, and change the routes they are rounding on every couple of weeks. Thus, the entire executive team is getting a sense of what is going on in the entire hospital, not just in their departments.

Rather than just “visiting,” they have a formal structure of questions, built from the Coaching Kata questions + some additional information. Since everyone is asking the same basic questions, the teams can be well prepared and the actual time spent in a particular department is programmed to be about 5 minutes. The schedule is tight, so there isn’t time to linger. This is deliberate.

After the teams round, the executives meet to share what they have learned, identify system-wide issues that need their attention, and reflect on what they have learned.

In this case, rather than rounding on patients, the executives are rounding to check the operational health of the hospital. They are checking the vital signs and making sure nothing is impeding people from doing the right thing – do people know the right thing to do? If not, then the executives know they need to provide clarity. Do people know how to do the right thing? If not, then the executives need to work on building capability and competence.

In both cases, executives are getting information they need so they can ensure that routine things happen routinely, and the right people are working to improve the right things, the right way. In the long-term, spending this time building those capabilities and mechanisms for alignment deep into the operational hierarchy gives those executives more time to deal with real strategic issues. Simply put, they are investing time now to build a far more robust organization that can take on bigger and bigger challenges with less and less drama.

Results

Though they were only a little more than a year in when Joe presented at KataCon, he reported some pretty interesting results. I’ll let you look at the presentation to see the statistically significant positive changes in employee surveys, patient safety and patient satisfaction scores. What I want to bring attention to are the cultural changes that he reported:

image

Leadership Development

Actually points 1. and 2. above are both about leadership development. The executives are far more in touch with what is happening, not only in their own departments, but in others. Even if they don’t round on their own departments, they hear from executives who did, and get valuable perspectives and questions from outsiders. This helps break down silo walls, build more robust horizontal linkages, and gives their people a stage to show what they are working on.

Since executives can’t be the ones with all of the solutions, they are (or should be) mostly concerned with developing the problem solving capabilities in their departments. At the same time, rounding gives them perspective on problems that only executive action can fix. In a many organizations mid-manager facing these systemic obstacles would try to work around them, ignore them, or just accept “that’s the way it is” and nothing gets done about these things. That breeds helplessness rather than empowerment.

On the other hand, if a manager should be able to solve the problem, then there is a leader development opportunity. That is the point when the executive should double down on ensuring the directors and upper managers are coaching well, have target conditions for developing their staff, and are aware of who is struggling and who is not. You can’t delegate knowing what is actually going on. Replying on reports from subordinates without ever checking in a couple of levels down invites well-meaning people to gloss over issues they don’t want to bother anyone about.

Breaking Down Silos by Providing Transparency

The side-benefit of this type of process is that the old cultures of “stay out of my area” silos get broken down. It becomes OK to raise problems. The opposite is a culture where executives consider it betrayal if someone mentions a problem to anyone outside of the department. That control of information and deliberate isolation in the name of maintaining power doesn’t work here. Nobody likes to work in a place like that. Once an organization has started down the road toward openness and no-blame problem solving, it’s hard to turn back without creating backlash of some kind within the ranks.

Creating Disruption

Joe used the term “Disruption” in the title of his presentation. Disruption is really more about emotions than process. There is a crucial period of transition because this new transparency makes people uncomfortable if they come from a long history of trying hard to make sure everything looks great in the eyes of the boss. Even if the top executive wants transparency and getting things out in the open, that often doesn’t play well with leaders who have been steeped in the opposite.

Thus, this process also gives a CEO and top leaders an opportunity to check, not only the responses of others, but their own responses, to the openness. If there are tensions, that is an opportunity to address them and seek to understand what is driving the fear.

In reality, that is very difficult. In our world of “just the facts, ma’am” we don’t like to talk about emotions, feelings, things that make us uncomfortable. Those things can be perceived as weakness, and in the Old World, weakness could never be shown. Being open about the issues can be a level of vulnerability that many executives haven’t been previously conditioned to handle. Inoculation happens by sticking with the process structure, even in the face of pushback, until people become comfortable with talking to each other openly and honestly. The cross-functional rounding into other departments is a vital part of this process. Backing off is like stopping taking your antibiotics because you feel better. It only emboldens the fear.

These kinds of changes can challenge people’s tacit assumptions about what is right or wrong. Emotions can run high – often without people even being aware of why.

Make Sure Failure = Learning

Take a look at this cool video from Space-X that highlights all of the failures that preceded their successful (and now more or less routine) landing of a recoverable orbital booster rocket. Then let’s discuss it a bit.

(Here is the direct link if you don’t get the embed in your feed: https://www.youtube.com/watch?v=bvim4rsNHkQ)

When we see failure, or even failure after failure, it is easy to forget that learning is rarely linear.

A Culture of Learning

Organizations like Space-X (and their counterparts such as Blue Origin) are in the business of learning. They are pushing the edges of what is known and moving into new territory. For organizations that understand that setbacks, mistakes, failures and the like are an inevitable part of learning, these things – while costly and unpleasant – are regarded as part of the process.

We have seen the same mechanisms in play – a process of experimentation toward progressive target conditions toward a visionary challenge – behind pretty much every breakthrough achievement throughout history.

No Mistakes = No Learning

At the opposite end of the spectrum are organizations with no tolerance for mistakes. They expect everything (and every one) to get everything right every time. They dismiss as incompetent any notion of failure, and attack as weakness any admission of “I don’t know” or “I don’t know how.”

A few years ago, as I was teaching Toyota Kata coaching with a client, a middle manager approached me during a break and said – point blank – that it was not his responsibility to develop his people. “Our policy is to hire competent people, and we expect them to be able to do the job.” He wasn’t the only one to say that, so I built the impression that this belief was, indeed, part of their culture. Needless to say they struggle a bit with getting innovation to happen because they try to mechanize the process.

Mistakes = Tuition

Here’s how I look at it. When a mistake happens – especially one that is expensive – you have paid considerable tuition. Your choice now is to either extract as much learning as you can from the event, or to try to ignore it and move on. The later choice is like paying your tuition up-front, then skipping all of your classes and wonder why you aren’t getting it.

Learning = Adapting to Change

Organizations that manage in ways that regard learning as part of their everyday experience are much more adaptive to changes and surprises than those who just execute their routines every day. The paradox here is that organizations who value learning are generally the most disciplined at following their routines. This discipline makes execution a hypothesis test, and they can quickly see when their process isn’t appropriate and adapt and learn quickly as an organization. They strengthen their routines, and through those routines, embed what they have learned in the organization’s DNA for future generations.

Organizations that figure it out as they go, on the other hand, tend to rely on individuals to adapt, but there is no mechanism to capture that learning beyond the individual or small group. Sometimes there is a “lessons learned” document, but that’s it. Those reports rarely result in the changes in organizational behavior that reflect learning. I suppose the most egregious case would be the loss of the space shuttle Columbia upon re-entry for exactly the same organizational failures that resulted in the loss of Challenger.

Technical vs. Cultural Learning

Space-X is solving a technical problem with science and engineering. I hope (and expect) that as they become more successful they will always be striving for something really hard that will drive them to the next level. Based on what I see publicly, I think that is embedded into their culture by Elon Musk. (But I don’t really know. If anyone from Space-X is reading this, how about getting in touch? I’d love to learn more.)

I expect this works for Space-X because they have a culture of learning.

What doesn’t work, though, is to try to apply technical solutions to transition a rote-execution culture into a learning culture. Changing the culture – the default behaviors and responses of people as they interact – isn’t about improving the mechanics of the work process. You certainly can work on the work processes, but the starting condition is what evolved in the context of the organization’s culture. The mechanics of the “improved” process that we try to duplicate evolved in the context of a learning culture. The ecosystems are different. It is difficult for a lean process to survive in a culture that expects everything to run perfectly and doesn’t have robust mechanisms to turn problems into improvements.

Creative Safety Supply: Kaizen Training and Research Page

Normally when I get an email from a company pointing me to the great lean resource on their web page, I find very little worth discussing. But Creative Safety Supply in Beaverton, Oregon has some interesting material that I think is worth taking a look at.

First, to be absolutely clear, I have not done business with them, nor do I have any business relationship. I can’t speak, one way or the other, about their products, customer service, etc

With that out of the way, I found their Kaizen Training and Research Page interesting enough to go through it here and comment on what I see.

What, exactly, is “PDCA?”

The section titled Kaizen History goes through one of the most thorough discussions of the evolution of what we call “PDCA” I have ever read, tracing back to Walter Shewhart. This is the only summary I have ever seen that addresses the parallel but divergent histories of PDCA through W. Edwards Deming on the one hand and Japanese management on the other. There has been a lot of confusion over the years about what “PDCA” actually is. It may well be that that confusion originates from the same term having similar but different definitions depending on the context. This section is summed up well here:

The Deming Circle VS. PDCA

In August of 1980, Deming was involved in a Roundtable Discussion on Product Quality–Japan vs. the United States. During the roundtable discussion, Deming said the following about his Deming Circle/PDSA and the Japanese PDCA Cycle, “They bear no relation to each other. The Deming circle is a quality control program. It is a plan for management. Four steps: Design it, make it, sell it, then test it in service. Repeat the four steps, over and over, redesign it, make it, etc. Maybe you could say that the Deming circle is for management, and the QC circle is for a group of people that work on faults encountered at the local level.”

So… I learned something! Way cool.

Rapid Change vs. Incremental Improvement

A little further down the page is a section titled Kaizen Philosophy. This section leans heavily on the thoughts / opinions of Masaaki Imai through his books and interviews. Today there is an ongoing debate within the lean community about the relative merits of making rapid, radical change, vs. the traditional Japanese approach of steady incremental improvement over the long-haul.

In my opinion, there is nothing inherently wrong with making quick, rapid changes IF they are treated as an experiment in the weeks following. You are running to an untested target condition. You will likely surface many problems and issues that were previously hidden. If you leave abandon the operators and supervisors to deal with those issues on their own, it is likely they simply don’t have the time, skill or clarity of purpose required to work through those obstacles and stabilize the new process.

You will quickly learn what the knowledge and skill gaps are, and need to be prepared to coach and mentor people through closing those gaps. This brings us to the section that I think should be at the very top of the web page:

Respect for People

Almost every discussion about kaizen and continuous improvement mentions that it is about people, and this page is no different. However in truth, the improvement culture we usually describe is process focused rather than people focused, and other than emphasizing the importance of getting ideas from the team, “employee engagement is often lip-service. There is, I think, a big difference between “employee engagement” and “engaging employees.” One is passive, waiting for people to say something. The other is active development of leaders.

Management and Standards

When we get into the role of management, the discussion turns somewhat traditional. Part of this, I think, is a common western interpretation of the word “standards” as things that are created and enforced by management.

According to Steve Spear (and other researchers), Toyota’s definition of “standard” is quite different. It is a process specification designed as a prediction. It is intended to provide a point of reference for the team so they can quickly see when circumstances force them to diverge from that baseline, revealing a previously unknown problem in the process.

Standards in this world are not something static that “management should make everyone aware of” when they change. Rather, standards are established by the team, for the team, so the team can use them as a target condition to drive their own work toward the next level.

This doesn’t mean that the work team is free to set any standard they like in a vacuum. This is the whole point of the daily interaction between leaders at all levels. The status-quo is always subjected to a challenge to move to a higher level. The process itself is predicted, and tested, to produce the intended quality at the predicted cost, in the predicted time, with the predicted resources. Because actual process and outcomes are continuously compared to the predicted process and outcomes, the whole system is designed to surface “unknowns” very quickly.

This, in turn, provides opportunities to develop people’s skills at dealing with these issues in near-real time. The whole point is to continuously develop the improvement skills at the work team level so we can see who the next generation of leaders are. (Ref: Liker and Convis, “The Toyota Way to Lean Leadership”)

Staging improvement as a special event, “limited time only” during which we ask people for input does not demonstrate respect, nor does it teach them to see and solve those small issues on a daily basis.

There’s more, but I’m going to stop here for now.

Summary

Creative Safety Supply clearly “gets it.” I think this page is well worth your time to read, but (and this is important), read it critically. There are actually elements of conflicting information on the page, which is awesome because it gives you (the reader) an opportunity to pause and think.

From that, I think this one-page summary really reflects the state of “lean” today: There IS NO CANONICAL DEFINITION. Anyone who asserts there is has, by definition, closed their mind to the alternatives.

We can look at “What Would Toyota Do?” as somewhat of a baseline, but ultimately we are talking about an organizational culture. Toyota does what they do because of the ways they structure how people interact with one another. Other companies may well achieve the same outcomes with different cultural mechanisms. But the interactions between people will override process mechanics every time.

Hopefully I created a lot of controversy here.  🙂
