What is “Recurrence Prevention Measures
Preventing a recurrence is to never repeat a failure that occurs for the same reason. Therefore, it is necessary to investigate the cause thoroughly and remove the cause.
A cause is not a superficial cause which can find on the surface,
but an underlying factor (root cause) which is in hiding in the in-depth.
In most cases, the root cause is not a person, but it lurks in the elements that constituting the system, such as structure, mechanism, system, and procedure.
A human error is just a trigger. The system is required to prevent a mistake
even if a person makes a mistake
"Once a failure has occurred, it is necessary to look back not only the technical side but also the work process. Investigate the cause where it came from in the work process"
