In today’s post, I am continuing with the theme of being inspired by philosophy. This post is inspired by the famous Austrian/British philosopher Ludwig Wittgenstein . In his posthumously published book “Philosophical Investigations” , Wittgenstein wrote;
“If a lion could talk, we could not understand him.”
One of the interpretations of this statement is that a lion has a totally different worldview than us, thus his values would be entirely different. Even though, we may have a common language, the intentions and interpretations would be completely different. A lion does not share a common frame of reference with us. The mutual understanding also depends upon whether we are interested in actively listening. Another aspect to think about is the non-verbal communication. The majority of human communication is non-verbal so simply talking does not convey the entire meaning. The meaning of a word depends upon the use of it within the context of a shared understanding.
When I was pondering about this, I started wondering whether we would understand if our process or gemba is “talking” to us. In some regards, they do talk to us through the visual controls we have in place. The visual controls lets us know how the process is going – but do we understand it?
The purpose of a visual control is to immediately make any abnormality, waste, or deviation visible so that we can immediately take action. Notice that I used “immediately” twice. This is how we should understand it. This sets the tone for how gemba talks to us. There are several ways that we fail to understand what the gemba is saying to us. A great resource for Visual controls is a collection of articles compiled from NKS Factory Management Journal, available in the form of the book “Visual Control Systems.”  Some of the ways Visual Controls can fail are;
1) A failure to understand what the visual controls are for:
One of the examples given of inadequate implementation of visual controls is to treat visual controls as a mere extension of 5S. The purpose of visual controls is, as noted above, to make abnormalities immediately visible. Additionally, action must be taken to address the problem.
2) Low problem consciousness among the employees:
If the employee is failing to make the abnormality visible, or if the supervisor / group leader or management is failing to take action immediately, the purpose of visual controls is being defeated. This leads to “business-as-usual” thinking.
3) Inadequate Visual Control Tools:
If there is no daily production board used, then any metric tracked is going to lead only to a delayed response. No timely action that can be taken. In a similar note, if the daily production board is located in a place that is not easy to see, the operators will not use it because of the inconvenience.
4) Lack of established standards for the visual controls:
In order to have the visual controls operate successfully, the establishment and dissemination of the rules of the visual controls must be performed. Everybody should know how to understand the visual control – what is the norm, what is good versus bad, signs something is abnormal etc.
I will finish off with a great Zen story that relates to the lack of understanding.
Provided he makes and wins an argument about Buddhism with those who live there, any wandering monk can remain in a Zen temple. If he is defeated, he has to move on. In a temple in the northern part of Japan two brother monks were dwelling together. The elder one was learned, but the younger one was stupid and had but one eye. A wandering monk came and asked for lodging, properly challenging them to a debate about the sublime teaching. The elder brother, tired that day from much studying, told the younger one to take his place. “Go and request the dialogue in silence,” he cautioned.
So the young monk and the stranger went to the shrine and sat down. Shortly afterwards the traveler rose and went in to the elder brother and said: “Your young brother is a wonderful fellow. He defeated me.”
“Relate the dialogue to me,” said the elder one.
“Well,” explained the traveler, “first I held up one finger, representing Buddha, the enlightened one. So he held up two fingers, signifying Buddha and his teaching. I held up three fingers, representing Buddha, his teaching, and his followers, living the harmonious life. Then he shook his clenched fist in my face, indicating that all three come from one realization. Thus he won and so I have no right to remain here.” With this, the traveler left.
“Where is that fellow?” asked the younger one, running in to his elder brother.
“I understand you won the debate.”
“Won nothing. I’m going to beat him up.”
“Tell me the subject of the debate,” asked the elder one.
“Why, the minute he saw me he held up one finger, insulting me by insinuating that I have only one eye. Since he was a stranger I thought I would be polite to him, so I held up two fingers, congratulating him that he has two eyes. Then the impolite wretch held up three fingers, suggesting that between us we only have three eyes. So I got mad and got ready to punch him, but he ran out and that ended it!”
Always keep on learning…
