Often meeting goes like,
Person 1 - this should do it
P2 - But if we do that, that will also cover that2 in future
P1, P3 - Make sense, let's do it.
P4 - We should also do that3.
All - Lets put up our points on a Doc, and discuss it again tomorrow. We shouldn't build something which we have to revisit in the future, it will be a waste of time otherwise.
All agree, adjourned.
(P1 to Pn are interchangeable)
I think when we are shielded from harsh realities of the market. We build something we want and consider cool. Not something that is useful.
So when you are actually engineering tangible real world items (eg cars and buildings) that have substantial embodied energy "over engineering" can sometimes actually mean making something of long term quality and value that lasts past fashion and trend.
