Regular readers of my blog know that I am a keen Japanophile. I love learning new things about the cultural nuances of Japan. In today’s post I will be looking at “Shisa Kanko” translated as “point with finger and call”.
Perhaps, like many others, when I was the last one to leave my house, I always questioned myself whether I closed the garage door. A mental trick I came up with was to talk to myself aloud as I pressed on the Garage Remote, “I am pressing on the remote”, and as the door closed I would remark again to myself, “look, the garage door is closing”. This action of talking it aloud created a physical and memory record that I could refer to later and recall that I did close the garage door.
Shisa Kanko is a similar process of “checking off” that an action was completed. Shisa Kanko is the process of pointing to something and calling out what happened. This could be a visual indicator for the status of an operation and calling out the status. This idea is said to have originated by a steam-train engineer of the name Yasoichi Hori. Hori started to lose his eye sight and thus began to call out the status signal to the fireman riding with hm. This was an attempt by Hori to not go through a wrong signal by mistake. The fireman would then repeat the status signal back to him and confirm it. This practice was deemed important and was implemented as a practice for railway staff. The practice of Shisa Kanko was published in the Japanese railway manual in 1913. You can read about the proper way to point and call at the old website of JICOSH (Japanese International Center for Occupational Safety and Health) .
This activity involves pointing at target objects by stretching your arm and stating out loud, “Such and such is OK” at important points in the work in order to proceed with work safely and correctly.
Pointing and calling are methods for raising the consciousness level of workers and confirming that conditions are regular and clear, increasing the accuracy and safety of work. This method for ensuring safety is based on the philosophy of respecting human life and can be achieved only with the full participation of the workforce in practice activities across the whole of the workplace.
It is said that implementing the practice of Shisa Kanko can reduce mistakes by about 85% percent . Shisa Kanko is a form of a checklist in some regards. By pointing and calling out, it is similar to the action of checking off on a checklist – “yup, this is done.” The physical and audible actions ensure that an important signal or action is not omitted. This is also an indicator to those around and provides an indication that an action was completed or the status of an operation. An example is the railway staff scanning to ensure that the tracks are free of debris before the train takes off. Instead of just scanning the tracks, the operator will point towards the track, making a sweeping action with the eyes following the hand. Once confirmed, the operator will announce that the track is clear.
Just like a checklist, the absence of Shisa Kanko will not always result in mistakes. However, the presence of Shisa Kanko will always aid in preventing mistakes. Thus it is a positive enabling constraint.
I will finish this post with a lesson from Buddha on learning to meditate;
Meditation can be a really hard skill to master and requires a lot of practice. Buddha’s advice is to make note of what is going on with your breath, similar to Shisa Kanko. Buddha’s lesson for mediation is “Anapanasati”. In Pali language “Ana” means “inhalation”, “pana” means “exhalation” and “sati” means “mindfulness”. Buddha is teaching us to be mindful of our breath going in (saying internally “in”), and going out (saying internally “out”). This practice of mindfulness, acknowledging the status of our breath, will allow us to be in control and in focus.
Buddha teaches about Anapanasati in the Anapanasati Sutta:
Breathing in long, he discerns, ‘I am breathing in long’; or breathing out long, he discerns, ‘I am breathing out long.’ Or breathing in short, he discerns, ‘I am breathing in short’; or breathing out short, he discerns, ‘I am breathing out short.’ He trains himself, ‘I will breathe in sensitive to the entire body.’ He trains himself, ‘I will breathe out sensitive to the entire body.’ He trains himself, ‘I will breathe in calming bodily fabrication.’ He trains himself, ‘I will breathe out calming bodily fabrication.‘
Always keep on learning…
