Organizations that operate QMS are required to take corrective action against nonconformities. Also, the cause of the nonconformity is expected to be identified.

However, useful cause analysis is complicated, and similar non conformances are often occurring.

In many cases, why is analysis adopted, and the cause is often narrowed down in one direction, but is there only one cause? Moreover, is the cause only a problem of the thing and the mechanism?

In the first place, how far do we pursue “why”?

QMS is a human-operated system, so it is not realistic to include human elements. In addition, excluding people from the cause can remove opportunities for learning by people and organizations.

◆Root Cause Analysis

  • It provides an opportunity to “learn” the problems that occur after unbiased evidence collection and visualization of the structure of the cause.
  • We will explore potential causes that were not visible from the table through a significant cut from a broad point of view, such as physical causes based on facts, causes of people, and those involved.
  • Ultimately, the aim is to “change people’s consciousness,” and the action of change by this consciousness means that the same thing will never happen again or not repeat it.


  • Because people involved in cause analysis change their knowledge, they do not repeat negative behavior.
  • You can break away from the tendency to blame someone and impose it on one person’s responsibility.
  • Enable you to notice small differences or unusual signs before a major accident or incompatibility occurs
