Before any tool — four questions

1Does the cause explain why — or only what and who?

2Could it apply to almost any event in the plant? Then it's too generic.

3Does the corrective action address that cause — or a convenient training package?

4Would someone who wasn't there know what to change?

It stops the rubber-stamp.
It does not certify the record.

Catching circular language is mechanical. Judging the real cause stays with the reviewer.
