# A Fuzzy 2018 Wish:

I wanted to write a good post for the New Year (2018). I have been thinking about a good “New Year’s” subject to write about for a while now. It is not easy to find topics to write about, and even if I find good topics, it has to pass my threshold level. As I was meditating on this, I came to think about procrastination and ambiguity. With these thoughts, I came to the topic for the post today. My post today is about the importance of “fuzzy concepts”. I am using the term fuzzy concept in a loose sense and will not go into depth or specifics.

We like to think in boxes or categories. It makes it easy for us to make inferences and aids in decision-making. “She is tall” or “He is short”; “this is hard” or “this is easy”. This is a reductionist approach and from a logic standpoint, this type of thinking is called “Boolean logic” and is based on a dichotomy of true or false (0 or 1). Something is either “X” or “not X”. This type of thinking has its merits sometimes.

In contrast, Fuzzy logic helps us in seeing the “in-between”. The fuzzy logic approach utilizes a spectrum viewpoint. It starts as 0 at one end and slowly increases bit by bit all the way to 1. We can express any point between 0 and 1 as a decimal value.

In the picture above, the left most point is white (0), and as we go towards right it changes the color to black (1.0) at the extreme right. Any point in between is neither white nor black. It is just in-between and we can identify the gradient as a value between 0 and 1.

In this vein, if I am to get myself to write a post for the New Year, I could be either prepared and ready OR not prepared and ready. I could wait for a long time for the inspiration to strike or to have an epiphany that would add value to the post. From a Boolean standpoint, this is black and white thinking. I have to wait until I am fully ready (1) to write the post. If I am not ready (0), I should not write the post.

The fuzzy thinking is not recent. In fact, there is an old Greek paradox called Sorites paradox, which is attributed to Megarian logician Eubulides of Miletus. The word “Sorites” is derived from the Greek word soros, which means “heap”. The paradox is as follows – if you have a heap of sand, and you take away a grain, would that heap still be a heap? What would happen if you keep taking grains away? At what point does it cease being a heap? We can express this in the Boolean logic as:  (1) = Heap, and (0) = No Heap. However, if we use the fuzzy logic, we could define what a full heap means and what “no heap” means. Anything in between can be defined as a “partial heap”. Fuzzy logic helps us to add a matter of degree to any statement.

The fuzzy logic concept goes really well with continuous improvement philosophy and the thought that lean is a journey and not a destination. We will never be 100% complete with our improvement. We are always incomplete with our improvement, and it is okay that we are incomplete. We have to keep on improving. We do not have to wait until we have the perfect idea or the expensive machinery or tool to start improving our processes. We do not have to wait for others to start on the improvement journey. In a Zen-like fashion, wherever we are, there we are – the right place to start improving. We will always be between 0 and 1 in terms of perfection of the process. We will always be on the journey and never at the destination. Taiichi Ohno, the father of Toyota Production System, had a great saying that encapsulates the fuzzy concept – Don’t seek perfection. 60 percent is good enough!

I will finish with a story I read online from an anonymous source.

The family was driving to their destination for their holiday. The child asked his father, “Are we there yet?”

The father replied, “No son. We are always here.”

I wish all of my readers a Fuzzy 2018. You are exactly where you are to start exactly what you want to start. Wherever you are, there you are!

Always keep on learning…

Excellent post. I agree that one of the reasons Lean is misunderstood and very often unable to be sustained is because companies/teams etc. are never “there”. In addition, most believe “there” has to be exactly where “there” is/was for Toyota, never looking for their own “there”, or better yet not needing a “there”.

This reminds me of quote from Fujio Cho, Chairman of Toyota Motors some time ago:
“We get brilliant results from average people managing brilliant processes. Our competitors get average results from brilliant people working around broken processes. When they get in trouble, they hire even more brilliant people. We are going to win.”

This quote relates to many different Lean concepts, but I think it relates to this topic in that others/competitors are trying to find their “there” by focusing on bringing in “the best” talent, automation, etc. they can find. When the improvement potential is many times right ‘there’ in their processes. Continuous improvement is about improving processes incrementally over time and sustaining this approach vs. getting “there” and stating, “We are done”. Sustaining a Lean Culture like the father to his son states is about realizing, accepting the ‘here’, because ” We are always, here”. Once this is realized, improvement ( and a Lean culture) can be sustained.

Categorical Vs Continuum Thinking. Neither is right or wrong. Both have their use. The key is to know what type of thinking you are using at any given time. Dr. Bill Bellows of the Deming Institute taught me about these two types of thinking.
