Procurement Corruption

> if there's no rule
Absolutely not: might as well roll a dice ;-) .  But whether or not the
regs are there, as often happens, the initial specs often contain weaknesses
(which is why you need humans in the loop, as already mentioned) and when
several suppliers meet the "requirements" it can come down to individual
persuasion, which is readily subject to the "Oh dear me, is that
the keys to a spare Jag/BMW/Rolls/Ferrari/[substitute own preference]
that I've left on the table?" syndrome.

And getting specs right can be *extremely* costly.
