A related concept to waste walks, the subject of our previous few posts, is the “Ohno Circle.”
Taiichi Ohno is credited for much of the thinking behind the Toyota
Production System, and he invented a novel method of making improvements. He would go to draw a chalk circle on the floor, and stand in it. He would stand for hours, watching and thinking about what he was seeing. He would look for what was getting in the way of people creating value and he would study the situation to determine what was causing it. This gave him the insight he needed to make lasting improvements.
Ohno’s approach is different from simply visiting “gemba” or touring the line, as it goes beyond “looking” to “watching.” Taking the time to actually watch work being done can pay big dividends, and often helps well-intentioned people avoid “learning too little and assuming too much.”
In fact, many CI leaders have confessed, after-the-fact, that, if they had simply stood in one place long enough to watch carefully, they would have quickly seen the true root causes of many problems that took weeks to solve.
