Totally agree Barbara. Not everything is feasible, which is why it’s so important that the intended design (which should have taken into account feasibility from the start) is not compromised.

I explain it like winning a game of chess when certain pieces are glued to the board.

My approach is to figure out which pieces I’ve got to play with, and then I figure out how to win. This is the design.

The challenges I’m talking about in my article are when people try to change the rules mid-game, or start glueing down more pieces mid-game. These are the things we must fight against, or the design won’t work as intended.

One thing about feasibility though, which has always stuck in my head:

If we were living in a world where only the technically feasible things were made, we’d all be getting around in horse & carriages.
