I accepted the certificate before examining the measurement need
Measurement provenance matters, but a technical leader still needs to connect the result and its uncertainty with the decision for which the instrument is being offered.
The document in front of me had the qualities that make an executive comfortable. It was orderly, specific and prepared through a recognised internal process. I could see how the measurement had been related to its reference. I supported the release because I treated that account as enough reassurance about the product's intended use. The subsequent quality challenge did not reveal that the document was meaningless. It revealed that I had asked it to answer a question beyond the one it had actually answered.
