Revolutionary Management Improvement May Be Needed But Most Management Change is Evolutionary

This month the ASQ Influential Bloggers were asked to respond to the question – will the future of quality be evolutionary or revolutionary?

I think it has been and will continue to be both.

Revolutionary change is powerful but very difficult for entrenched people and organizations to actually pull off. It is much easy to dream about doing so.

Often even revolutionary ideas are adopted in a more evolutionary way: partial adoption of some practices based on the insight provided by the revolutionary idea. I think this is where the biggest impact of W. Edwards Deming’s ideas have been. I see him as the most revolutionary and worthwhile management thinker we have had. But even so, few organizations adopted the revolutionary ideas. Most organizations nibbled on the edges and still have a long way to go to finally get to a management system he was prompting 30,40 or more years ago.

A few organizations really did some revolutionary things based on Deming’s ideas, for example: Toyota. Toyota had some revolutionary moves and adopted many revolutionary ideas brought forward by numerous people including Taichii Ohno. But even so the largest impact has been all those that have followed after Toyota with the lean manufacturing strategies.

And most other companies have taken evolutionary steps from old management paradigms to adopt some new thinking when trying out lean thinking. And frankly most of those efforts are so misguided or incredible small they barely qualify. But for those that successfully improved their management system they were mainly evolutionary.

Toyota Understands Robots are Best Used to Enhance the Value Employees Provide

Toyota has always seen robotics as a way to enhance what staff can do. Many USA executives think of robotics as a way to reduce personnel. Toyota wants to use the brainpower of employees to continually improve the organization. Toyota wants to free people for monotonous or dangerous work to let them use their minds.

Humans Steal Jobs From Robots at Toyota

Humans are taking the place of machines in plants across Japan so workers can develop new skills and figure out ways to improve production lines and the car-building process.

“We cannot simply depend on the machines that only repeat the same task over and over again,” Kawai said. “To be the master of the machine, you have to have the knowledge and the skills to teach the machine.”

Kawai, 65, started with Toyota during the era of Taiichi Ohno, the father of the Toyota Production System envied by the auto industry for decades with its combination of efficiency and quality. That means Kawai has been living most of his life adhering to principles of kaizen, or continuous improvement, and monozukuri, which translates to the art of making things.

“Fully automated machines don’t evolve on their own,” said Takahiro Fujimoto, a professor at the University of Tokyo’s Manufacturing Management Research Center. “Mechanization itself doesn’t harm, but sticking to a specific mechanization may lead to omission of kaizen and improvement.”

We need more companies to learn from the executives at Toyota. They show real respect for people. They are not focused on how much they can extract from the corporate treasury to build themselves castles at the expense of other employees, customers and stockholders as far too many USA executives are.

Toyota has been extremely innovative in investing in robotics as human assistants (partially this is due to the extreme demographic problems Japan faces): Toyota Develops Thought-controlled WheelchairToyota’s Partner RobotToyota Winglet – Personal Transportation Assistance.

Business 901 Podcast with Me: Deming’s Management Ideas Today

I recently was interviewed for a podcast by Joe Dager, at Business 901: Dr. Deming on Lean in 2012. I hope you enjoy the podcast.

Listen to this podcast.

Here are some links related to items I mention in the podcast:

Some blog posts that expand on some points I made in the podcast:

Transcript of the interview.

Respect for Everyone

TL;DR – The two pillars of the Toyota Way are: respect for people and continuous improvement.

One of the big reasons my career followed the path it did (into management improvement) was due to the impact of respect for people. My father was a professor (in statistics, engineering and business) and consulted with organizations to help them achieve better results. To achieve results he took advantage of the gains possible when using statistical tools to manage with respect for people.

Managing Our Way to Economic Success: Two Untapped Resources, 1986: “American organizations could compete much better at home and abroad if they would learn to tap the potential information inherent in all processes and the creativity inherent in all employees.”

After he died, for years, people would talk to me about the difference he made in their lives (at conferences mainly). Other than those with PhD’s in statistics (of which there were many, but a very small number compared to all the others) the thing that made a difference was respect for people. Those who chose to talk to me are obviously a self selected group. But of those, the people that made the largest impact on me basically said he talked to me as though everything I said mattered. He didn’t talk down to me. He helped me see how I could help improve: the organization and my own skills and abilities.

This didn’t happen 5 times or 10 times of 20 times, it happened many more times than that. Year after year of this helped push me to stick with management improvement. These served as a great incentive to perserve as I ran into the typical difficulties actually improving management systems.

The senior executives he talked to were not very impressed that he spoke to them with respect. So none mentioned that with awe, but a few did notice that he was able to connect with everyone – the senior executives, nurses, people on the factory floor, secretaries, salespeople, front line staff, engineers, janitors, middle managers, doctors, union leaders. The senior executives were more likely to be impressed by the success and his technical ability and knowledge as well as communication skill. Doctors, statisticians and engineers were more impressed with knowledge, technical skill, skill as a teacher and advice.

Long Term Thinking with Respect for People

Toyota nearly went bankrupt near 1950 and had to lay off a third of their employees. A huge focus of the Toyota Production System as envisioned by Taiichi Ohno was to secure the long term success of the company. The priority of doing so is easier to see when you respect people and are in danger of witnessing the destruction of their careers.

I can’t find the quote (maybe Jon Miller, or someone else, can provide one), but I recall one along the lines of the first priority of management is providing long term viability of the company (my sense is this is first due to the respect of the workers and also for all the other stakeholders). The respect for people principle requires executive put the long term success of employees at the top of their thinking when making decisions for the company. I don’t believe it is a ranked list I believe there are several things right at the top that can’t be compromised (respect for people, safety of society, support for customers…).

This means innovating (Toyota Management System, Toyota Prius, Toyota Robots, Lexus brand, etc.) and seeking growth and profit with long term safety that does not risk the failure of the company. And it means planning for the worst case and making sure survivability (without layoffs etc.) is nearly assured. Only when that requirement is met are risks allowed. You do not leverage your company to put it at risk of failure in dire economic conditions even if that would allow you to be more profitable by various measures today. And you certainly don’t leverage just to take out big paychecks for a few short term thinkers.

The economic situation today is extremely uncertain. The whole eurozone financial situation is very questionable. The government debt burden in the USA and Japan is far too high (and of course Europe). China is still far from being a strong economy (they are huge, fast growing and powerful but it is still fairly fragile and risky).

The failures in the current financial system have not been addressed. Band-aids were applied to provide welfare to the largest 30 financial institutions in the form of hundreds of billions or trillions in aid. The system was left largely untouched. It is hard to imagine a more textbook example of failing to fix the causes and just treating the symptoms. This leaves a huge financial risk poised to cause havoc.

Lean Manufacturing and the Toyota Production System

In this post I explore my thoughts about what lean (lean manufacturing, lean thinking…) means. The way I think about it is that lean manufacturing sprung from Toyota. It seems to me the lean manufacturing name was meant to capture the entire Toyota Way. Capturing the whole of what that encompasses isn’t possible in 1 or 2 or even 10 books so it wasn’t done completely.

To me the difference between lean manufacturing described early on by Womack and Jones and the Toyota Way was more about what can be captured and conveyed than about an intentional creation of “lean” ways that are different than Toyota ways.

The question is further complicated by what happens with any management idea of any popularity: the using of the name with all sorts of watered down and even just plain not-lean implementations. So much of what is called “lean” is not the Toyota Production System (TPS), it isn’t even lean.

It seems to me today there is no real accepted authority for what is lean. LEI is good. Some people might say they should be the arbiter but they are not in any way I know of.

Then too, over time any organization of people changes. So what Toyota does today isn’t exactly what Taiichi Ohno would say they should be doing. Even the Toyota Way can be ignored by Toyota. And Ohno certainly wouldn’t think standing still was the answer. Just like Deming; Kiichiro, Sakichi and Shoichiro Toyoda; Ohno expected the management system itself to continually improve. And just like Deming, they would expect the implementation in a different organization (different system) to be different.

The Need to Improve Management While Building Organizations Fit For Human Beings

Gary Hamel: Reinventing the Technology of Human Accomplishment

I agree with Gary Hamel that we need to adopt new management strategies. I happen to believe most of new strategies we need to adopt have been known for decades, we just fail to implement many of them.

He argues it is hard to retain knowledge advantages (within companies). I agree. However execution advantages it seems to me are not that difficult to maintain. Few companies actually focus on the customer and continual improvement. Toyota can be incredibly open but still few others are not willing to actually put in the effort to execute fully.

The reverse accountability idea he discusses I don’t love as much as he does. I do believe it is good to value the entire workforce more and not base decisions on HiPPOs. Accountability is a loaded term, in my opinion. Even in he talk he focuses on the “fear” – if the supervisor doesn’t fix the issue to the reporters satisfaction in 24 hours it is escalated to the next level. The process could be better, without what seems like driving in fear, to me.

I agree that the best management strategy is to adopt the thinking he captures with “you cannot build a company that is fit for the future, without building one that is fit for human beings.” The part I don’t agree with is phrase he lead that quote with: “Because I think for the first time since the industrial revolution…” isn’t right. I think Dr. Deming taught that idea to Japan in the 1950’s and as we all know Toyota adopted as the core “Respect for People” principle. That concept was important in 1950. That management idea is needed. Adopting that principle would be new for many of our organizations. But it also is true that the idea has been known for decades.

I return to this theme frequently. We don’t need many new ideas. We just need to adopt the good ideas that have been proven for decades. The new ideas are mainly just a bit of flavoring to tweak the good ideas we have had available and just chosen to ignore.

Respect for People Doesn’t Mean Avoiding Any Hint of Criticism

As I said in a post a few years ago on respect for people and Taiichi Ohno‘s sometimes very aggressive style:

The difference between respect and disrespect is not avoiding avoiding criticism. In fact often if you respect someone you can be much more direct and critical than you can with someone you treat as though they don’t have the ability to listen to hard truths and improve. I think we often have so little respect for people we just avoid dealing with anything touchy because we don’t want to risk they won’t be able to react to the issues raised and will instead just react as if they have been personally attacked.

Masaaki Imai described Taiichi Ohno’s style this way

he had such a high expectation of the staff and managers under him. If they were not doing something the right way, he would explode. And when he exploded, he really would explode.

But for those who came to him and really asked for help, he was very patient. He wouldn’t give them the answer, but preferred to provide them with enough of an understanding of the situation, as well as help on how they could deal with the problem. So he was very much a teacher and a leader.

I would say that while Taiichi Ohno was truly remarkable that doesn’t mean he did everything right. And he might well have failed to communicate in a way that conveyed respect for people fully, when he exploded. He was great, but his methods could also be improved. At the same time some extent showing some fire may be helpful at times to get people to take things seriously (avoiding the need for this is even better, but not everything will be done as well as it possible can be).

Good Process Improvement Practices

Good process improvement practices include:

  • standardized improvement process (pdsa, or whatever)
  • Going to the gemba – improvement is done where the work is done. You must go to the where the action is. Sitting in meeting rooms, or offices, reading reports and making decisions is not the way to improve effectively.
  • evidence based decision making, data guides decision making rather than HiPPO
  • broad participation (those working on the process should be the ones working on improving it and everyone in the organization should be improving their processes)
  • measurable results that are used to measure effectiveness
  • pilot improvement on a small scale, after results are shown to be improvements deploy standardized solutions more broadly
  • visual management
  • Standardized work instructions are used for processes
  • one of the aims of the improvement process should be improving peoples ability to improve over the long term (one outcome of the process should be a better process another should be that people learned and can apply what they learned in future improvements)
  • quality tools should be used, people should be trained on such tools. The tools are essentially standardized methods that have been shown to be effective. And most organization just ignore them and struggle to reinvent methods to achieve results instead of just applying methods already shown to be very effective.
  • the improvements are sustained. Changes are made to the system and they are adopted: this seems obvious but far too often process improvements are really just band-aids that fall off a few weeks later and nothing is done to sustain it.
  • goals, bonuses and extrinsic motivation are not part of the process
  • The improvement process itself should be continually improved

The Toyota Way – Two Pillars

Toyota is receiving plenty of criticism now, much of it for good reason. There is also a large amount of psychology involved. From what I have seen, the insurance companies still see better claims history (fewer and lower cost claims) against Toyota than other manufacturers. And there is another strain that seems to enjoy criticizing what has been praised. Toyota does need to improve. But that is improvement of the existing management system, not a need to radically change the management of the company.

I think Toyota, even with the problems, is a fantastic example of a very well managed company. Yet even with all the study of lean manufacturing even basic ideas are overlooked. For example, the two main pillars of the Toyota way are “continuous improvement” and “respect for people.” For all of us, it is valuable to refocusing on core principles. We are too often looking for the next new idea.

This is one way of looking at the pillars of the Toyota Production System, from the Toyota Technical Center – Austrailia

Image of Toyota's pillars of management: respect for people and continuous improvement

Continuous Improvement means that we never perceive current success as our final achievement. We are never satisfied with where we are and always improve our business by putting forth our best ideas and efforts: we are keen to create better alternatives, question our accomplishments and investigate future definitions of success.

There are three building blocks shaping our commitment to Continuous Improvement:

1. Challenge – we form a long term vision, meeting challenges with courage and creativity to realize our dreams;
2. Kaizen – we improve our business operations continuously, always driving for innovation and evolution
3. Genchi Genbutsu – we go to the source to find the facts to make correct decisions, build consensus and achieve goals.

Respect For People refers to our own staff as well as the communities and stakeholder groups that surround us and we are part of. We respect our people and believe the success of our business is created by individual efforts and good teamwork.

Respect For People is translated in:

1. Respect – we respect others, make every effort to understand each other, take responsibility and do our best to build mutual trust
2. Teamwork – we stimulate personal and professional growth, share the opportunities of development and maximize individual and team performance.

These elements combined define our corporate DNA, provide a way of operating that is recognised by each and every Toyota-member around the globe and enables us to sustain our success in the future.

Back to Basics for Toyota by Akio Toyoda

When my grandfather brought Toyota into the auto business in 1937, he created a set of principles that has always guided how we operate. We call it the Toyota Way, and its pillars are “respect for people” and “continuous improvement.” I believe in these core principles. And I am convinced that the only way for Toyota to emerge stronger from this experience is to adhere more closely to them.

While recent events show Toyota obviously needs to improve, that has been true all along (it is just more obvious lately). Some may see this as an indication that these lean manufacturing ideas based on Toyota’s practices are no better than other management practices. I don’t believe this. I feel just as strongly about the value of lean management as ever. I think that the recent events show you that no matter how well an organization in managed there is plenty of room to improve. Toyota never was close to perfection. They have much to improve, but they are still one of the best managed companies in the world.

My comments in 2005:

I think the instances of such failures are just a sign that even Toyota still has quite a bit to improve. I think this announcement likely is a result of common cause variation (it is the natural result of the current system). The natural result (of the system) is not that they have this particular failure, but that this recall is consistent with the % of vehicles that required a recall of this general character. I believe they are getting better over time but they still have a long way to go. With a result based on common cause you want to look at the entire system when designing an improvement plan not at the root cause of the seat belt issue. See Responding to Variation online and the book, Forth Generation Management, by Brian Joiner.

And my comments in 2007:

I don’t agree that they need to rethink their purpose in life (I have a feeling that is taken out of context). They need to maintain and maybe even increase their commitment to their purpose in life.
