The pointing and calling method, known as "Shisa Kanko" in Japanese (指差喚呼), is a safety procedure used extensively in Japan, particularly in the railway system, to minimize errors and enhance focus. It involves physically pointing at a relevant indicator or control while verbally announcing its status. This dual action engages both visual and auditory senses, reinforcing attention and reducing the likelihood of mistakes.
Core Concept: Operators point at specific indicators (like signals, gauges, or controls) and verbally announce what they are observing or doing.
- Example:A train driver might point at a signal displaying a green light and say, "Signal is green, proceeding."This method has been shown to significantly reduce errors and accidents in various industries, especially in the Japanese railway system, where it's been a key factor in maintaining high safety standards.Widespread Use: While originating in the railway sector, pointing and calling is now used in many Japanese industries, including manufacturing, construction, and even in some office settings.Cognitive Impact: Studies suggest that pointing and calling activates different parts of the brain compared to simply looking or thinking about a task, further enhancing its effectiveness in preventing errors.Watch "Pointing and Calling – A simple way to reduce automation bias" on YouTube
