“The value of genchi genbutsu isn’t necessarily the specific act of going and seeing, but the philosophy of deeply understanding the current condition before making a decision or trying to change something that you think will be an improvement. There are two main aspects of genchi genbutsu. First, decisions are made based on observed facts about the issue, rather than on hunches, assumptions, or perceptions. Second, decisions should be put into the hands of those closest to the problem and those who have gone to see it and have a deep understanding of its causes and the possible impact of proposed solutions.”
