Mistake made. Mistake recognised. Mistake resolved. Why all the fuss? That's after all why we have SOP's and the like.
Have you never made a mistake?
Time to move on me thinks.
Amen brother.
The man who never made a mistrake never made anything.
Our job is to learn from both our own mistakes and those of others, SOPs are not just standard procedures, they are the checks and balances which should ensure that our mistakes are recognised and corrected before they become a problem.
