Best Practice - yuk!

Am I alone in finding the phrase 'Best Practice' at best irritating and at worst deeply pretentious? How many companies have I worked in where the local Best Practice (and yes, it is always capitalised) would embarrass a mentally challenged nine-year old child? What is it about organisations that, although not yet capable even of good practice, makes them emblazon their half-baked bureaucratic nightmares with such an utterly inappropriate title?
