Taiichi Ohno is known to have said that “having no problems is the biggest problem of all.” He viewed problems not as a negative but as a “Kaizen opportunity in disguise.” Whenever problems arose, he encouraged his staff to investigate the problem at the source and to as “ask ‘why’ five times about every matter (src).”
In a series of events, where people are involved, mistakes happen. Functional areas such software engineering, industrial engineering or more general areas such as medicine, law, or sociology — these areas are composed by a series of events, involving people, process, machines, environment, and other items. Undoubtedly, mistakes will happen. What typically happens in response to mistakes is that blame is thrown around, which builds resistance, then communication fails which could lead to project failure. The better approach is to identify the root causes of mistakes and attacking that, instead of what might be perceived as the cause: Perceived causes are most likely symptoms and not the root cause, in which case the problem was never really solved. This, more rigorous and long-lasting, approach to solving problems is called Root Cause Analysis.
