Factorial Designed Experiment Aim

Multivariate experiments are a very powerful management tool to learn and improve performance. Experiments in general, and designed factorial experiments in particular, are dramatically underused by managers. A question on LinkedIn asks?

When doing a DOE we select factors with levels to induce purposely changes in the response variable. Do we want the response variable to move within the specs of the customers? Or it doesn’t matter since we are learning about the process?

The aim needs to consider what you are trying to learn, costs and potential rewards. Weighing the various factors will determine if you want to aim to keep results within specification or can try options that are likely to return results that are outside of specs.

If the effort was looking for breakthrough improvement and costs of running experiments that might produce results outside of spec were low then specs wouldn’t matter much. If the costs of running experiments are very high (compared with expectations of results) then you may well want to try designed experiment values that you anticipate will still produce results within specs.

There are various ways costs come into play. Here I am mainly looking at the costs as (costs – revenue). For example the case where if the results are withing spec and can be used the costs (net costs, including revenue) of the experiment run are substantially lower.

Engage in Improving the Management System

To actually improve management you need to engage in continual improvement of your management systems. This requires doing the hard work of challenging complacency. The job of those improving the practice of management is not to make everyone happy and just ignore that the words about improvement are not actually carrying through to changes in behavior.

Do Executives “Get It?”

So many times executives spout the importance of new initiatives like wellness programs, safety programs, or improvement projects like Lean, Six Sigma, etc. They talk about how great they are and how everyone should embrace them so the company can improve, but when push comes to shove, their actions indicate they really don’t believe in them.

If you are trying to bring about change you need in-process indications of actual success at improving the management system. Instead it seems to me, most of the time, the focus is on spinning what is being done to convince others that what is being done is good. This is not helpful and not useful.

Without in-process indications of how the movement to a better management system is performing the pattern is all too common. People want to show they are doing a good job (which often includes not being too negative – because if they criticize results they can be branded as negative). So instead we end up with actions that would be used if one assumed that while we had problems with the last 4 management fads we implemented, now we have this wonderful new idea it will avoid all the problems.

So we start our new process, and write up reports and presentations for meetings talking about our successes. We are careful to ignore any warning signs. Then, after 1, 2… years (in a good economy this can last quite a bit longer), the boss says the results are not improving, this isn’t working. Everyone quickly agrees and the improvement effort is dropped. Usually there will be a period of time taken until and a new fad is found that everyone agrees is wonderful for 2-5 years until they then all agree was a failure. Repeat for the rest of your career.

To break this cycle and actually continually improve we can’t go along with the in-process indications that the management improvement system is not really working. We need to seek out indications that it is not working and address those issues and build a strong continually improving management system.

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

Respect People: Trust Them to Use good Judgment

Nordstrom’s employee handbook used to be presented on a single 5 x 8 card:

Welcome to Nordstrom
We’re glad to have you with our Company. Our number one goal is to provide outstanding customer service. Set both your personal and professional goals high. We have great confidence in your ability to achieve them. So our employee handbook is very simple.

We have only one rule: Use good judgment in all situations.

Please feel free to ask your department manager, store manager, or division general manager any question at any time.

That is no longer the case, however, as they have become more like everyone else. Simple ideas like this only work within the right context. Taking such ideas and applying them to an organization that isn’t ready will backfire. But if you build a culture where trust, respect, customer service and responsibility are encouraged lots of rules just get in the way of people doing their best. If you can’t trust employees to do their jobs, the problem is with the system you have that results in that, not the people you can’t trust.

A Theory of a System for Educators and Managers

Excerpts from The Deming Library Volume XXI, Dr. W. Edwards Deming, Dr. Russell Ackoff and David Langford demonstrate that educators can begin a quality transformation by developing an understanding of the properties and powers of systems-oriented thinking. You can order the entire video, as well as the rest of The Deming Library.

Great stuff! If you enjoy this blog (the Curious Cat Management Improvement Blog), you definitely should watch this webcast. This video has some great insight into education, learning and systems thinking. It also provides a good explanation of systems thinking compared to analysis. Dr. Ackoff: “You cannot explain the behavior of a system by analysis.” “The performance of the whole is never the sum of the performance of the parts taken separately: but it’s the product of their interactions. Therefore, the basic managerial idea introduced by systems thinking is that to manage a system effectively you must focus on the interactions of the parts rather than their behavior taken separately.”

Dr. Deming: “You may reduce defects to zero and go out of business.”

Dr. Ackoff: “Most discussion of education assume that the best way to learn a subject is to have it taught to you. That’s nonsense… Teaching is a wonderful way to learn. Therefore if we want people to learn we have to make them teach.” If you want more on this see David Langford’s work which provides great advice on how to improve learning and education.

Positivity and Joy in Work

John and Bill Hunter

After my father died, for years (at least 10), people I never had met before would emotionally share what a positive influence he had on their lives. He did great stuff helping organizations improve. But the majority of people were not telling me how much he helped the organization improve [there were also a bunch of engineers and statisticians 🙂 that were more impressed with his insights and expertise]. But most people talked about was how much happier they were because of the changes he helped them see they could make in their lives.

He helped them expect to take joy from work and so they did (and a big part in taking joy in work for most is helping others take joy in work – you don’t find many workplaces with 15 miserable people and one joyful person). Many had to leave their current organizations that were too broken for them to fix. But after they saw what they should expect they couldn’t just keep passing time without joy in work.

Now I am sure their were hundreds of people that never talked to me that never made any such change. But the number of people that did took what was a decent chance that I would continue working with the management ideas I absorbed from him (data based decision making, Deming, joy in work, respect for people…) and made it a very great one. Unfortunately I am nowhere near as affective as he was.

Creating organization that show respect for people in the workplace and give them tools to improve is far more powerful than most people understand. Most people get scared about “soft” “mushy” sounding ideas like “joy in work.” I have to say I sympathize with those people. But it is true.

To get “joy in work” it isn’t about eliminating annoyances. Fundamentally it is about taking pride in what you do and eliminating the practices in so many organizations that dehumanize people. And to create a system where the vast majority of people can have joy in work most of the time requires a deep understanding and application of modern management improvement practices (Deming, lean thinking, etc.).

Dee Hock on Hiring

Great quote from Dee Hock, founder of Visa:

Hire and promote first on the basis of integrity; second, motivation; third, capacity; fourth, understanding; fifth, knowledge; and last and least, experience. Without integrity, motivation is dangerous; without motivation, capacity is impotent; without capacity, understanding is limited; without understanding, knowledge is meaningless; without knowledge, experience is blind. Experience is easy to provide and quickly put to good use by people with all the other qualities.

Build an Environment Where Intrinsic Motivation Flourishes

50 years after Douglas McGregor’s classic, The Human Side of Enterprise, too many managers still have not learned that using extrinsic motivation is not an effective way to manage complex human systems (organizations). The issue is important to me because their is a huge amount of poor management based on this thinking (focused on how people need to be fixed/motivated) instead of fixing what management really needs to fix.

You can succeed as a manager, and progress in your career, by viewing your role as helping people do their jobs well. As McGregor shows workers want to do a good job. He termed managing with this understanding theory y; and theory x is the idea that people should be motivated with carrots and sticks because they are not going to do work otherwise. Organizations have often so systemically de-motivated people they seem to have lost that desire. What you need to focus on is not motivating them with cheap tricks. Instead focus on eliminating the factors that de-motivate them.

Often simplistic motivation is seen as a replacement for fixing management performance (improving the management systems…). Instead managers should focus on eliminating the sources of de-motivation in the workplace. If you need hints, Dilbert does a good job of showing you what management does that de-motivates.

To succeed as a manager assume people wish to do a good job. If employees are not performing some task well, the manager needs to figure out what is wrong with the system that leads to this outcome (not what is wrong with the employees). When a manager views the problem as one of motivating workers that puts the problem within the worker. They need to be changed. That is the wrong strategy, most of the time. Instead you will have much more success if you seek to improve the system to improve performance.

I believe there is often a burden to overcome. As people have their intrinsic motivation crushed time after time day after day, week after week, year after year they try to protect themselves by shutting off their hope to achieve intrinsic motivation at work. You may have to show you really are serious before they will open up again. You have to make real changes and do so consistently that shows respect for people. Intrinsic motivation is a strong force and a few earlier adopters will quickly come along in all but the most broken organizations. You can build on that success (and eliminat more and more de-motivation) to grow intrinsic motivation in more and more people.

How to Manage What You Can’t Measure

In Out of the Crisis, page 121, Dr. Deming wrote:

the most important figures that one needs for management are unknown or unknowable (Lloyd S. Nelson, director of statistical methods for the Nashua corporation), but successful management must nevertheless take account of them.

So what do you do then? I am a strong advocate of Deming’s ideas on management. I see understanding system thinking, psychology, the theory of knowledge and variation as the tools to use when you can’t get precise measures (or when you can).

Even if you can’t measure exactly what you want, you can learn about the area with related data. You are not able to measure the exact benefit of a happy customer but you can get measures that give you evidence of the value and even magnitude. And you can get measures of the costs of dis-satisfied customers. I just mention this to be clear getting data is very useful and most organizations need to focus on gathering sensible data and using it well.

Without precise measures though you must use judgment. Judgment will often be better with an understanding of theory and repeated attempts to test those theories and learn. Understanding variation can be used even if you don’t have control charts and data. Over-reaction to special causes is very common. Even without data, this idea can be used to guide your thoughts.

The danger is that we mistake measures for the thing itself. Measures are a proxy and we need to understand the limitation of the data we use. The main point Deming was making was we can’t just pretend the data we have tells us everything we need to know. We need to think. We need to understand that the data is useful but the limitations need to be remembered.

Human systems involve people. To manage human systems you need to learn about psychology. Paying attention to what research can show about motivation, fear, trust, etc. is important and valuable. It aids management decisions when you can’t get the exact data that you would like. If people are unhappy you can see it. You may also be able to measure aspects of this (increased sick leave, increased turnover…). If people are unhappy they often will not be as pleasant to interact with as people who are happy. You can make judgments about the problems created by internal systems that rob people of joy in work and prevent them from helping customers.

For me the key is to use the Deming’s management system to guide action when you can’t get clear data. We should keep trying to find measures that will help. In my experience even though there are many instances where we can get definite data on exactly what we want we fail to get data that would help guide actions a great deal). Then we need to understand the limitations of the data we can gather. And then we need to continually improve and continually learn.

When you have clear data, Deming’s ideas are also valuable. But when the data is lacking it is even more important to take a systemic approach to making management decisions. Falling back into using the numbers you can get to drive decision making is a recipe for trouble.
