August is the holiday month, so this is a somewhat lighter
There's an expression that someone "gives their imprimatur", implying approval.
http://en.wikipedia.org/wiki/Imprimatur The word 'imprimatur' is Latin for "Let it be printed", and it comes from procedures devised in 1559 by the Catholic hierarchy to check and control documents to be sure no heresy was being disseminated. Here are the rules for a triple lock on information quality, with their translation:1. Concordat cum Originali (In agreement with the orginal documents)
In modern terms, this would mean that document control procedures would include:
1. Check that the data in the report has been reconciled to the source data. Managers often complain that it is not clear to them where figures have come from. Check that no data is missing, that no spurious data has been added; ie it reflects the source, the whole of the source, and nothing but the source, When that line has been clearly drawn, then the necessary assumptions, interpolations, adjustments and projections can be clearly distinguished.
2. Review the output by someone, other than the author, who understands the reasoning behind the calculations and the significance of the data. They need to sign off that they find no defects in the document.
3. Have the boss take personal responsibility to approve the printed document before it is used by whatever decision process it supports.
Not bad for rules that are 450 years old!
After a McAfee-run security conference in Australia this
month, a McAfee representative reportedly attached a spreadsheet with
hundreds of guests’ personal information to a mass-mailed thank you
note. The spreadsheet was said to have to contained names, phone
numbers, e-mail addresses, employment information, and even dietary
requirements of more than 1400 people.
“This is a dangerously high level of malicious irony,” an analyst warns. “We have not seen levels this high since the Windows Vista Compatibility Center suffered compatibility issues at its launch in 2008.”
