No one in their right—or left—mind would knowingly set something up to fail but too often they do just that without realizing it. If you’re like most folks and know an audit is coming, you will check many details beforehand to avoid being written up for one oversight or another. These checks will include making sure that your gage and instrument calibration is current and you’ve got the reports to support it. However, if that’s all you review in this area, you could be in trouble.
Too often reports are filed after a cursory glance at them for red flags but, as is often said, the devil is in the details and those details can cause trouble. The data in those reports may look satisfactory but an auditor will want to know what your acceptance criteria is for the set. The easy way out is to specify a grade but that is what can trip you up later when the set no longer meets that grade. The spec may have been valid for a new set but once the blocks have been used may no longer meet it.
