Architect? No, more Urban Planner
IT is NOT building, it is more like a city.
We tend to think about IT architect in terms of cathedral planner, while in fact Michelangelo was only the¿greatest? of a series.
A big company´s IT is a city, with a Gothic cathedral with Romanic altar, Roman crypt, Greek temple foundations and neolithic burials underneath.
But what about the merchant´s house? and the king´s palace? and the old quarter ?
Not to mention the enbankment, the Wharf, the City, etc.
So there is not A Chief IT architect, but a lot of them , each with his small building, depending on the Council Planners for Infrastructure.
Have a look around where you live.
THAT is the problem.
