The trick is knowing.......

Je ne résiste pas à le tentation de soumettre à vos réflexions cette citation de Ken Orr  (Cf. photo) :

There are some things that computers  do better than people and some things that people do better than computers : the trick is knowing which is which. Given the right set  of consistent business rules, computers can come up with the same answer time after time, and do so not in months or years (or sometimes decades), but in microseconds. Clearly one of the reasons that computer systems have become so important in advanced organizations elsewhere is this ability to get the right answer instantly. But getting the right answer is only possible if one has a consistent  way to define and develop a simple business rule or a small set of business rules; as the number of rules and decisions grows, the problem gets exponentialyy more difficult.
