Great saying!

Agile or Extreme Programming doesn't mean ignoring architecture or analysis by any means, it just questions the viability of a fixed spec. Seems to me - at least in my own work - that allowing an app to evolve in short iteration cycles with client feedback means architecture (at least in one's undertstanding of the overall business problem ) is even more important. Kind of like knowing what key you are in in jazz improvisation.
