fioricet To those accustomed to the precise, structured methods of conventional
     system development, exploratory development techniques may seem messy,
     inelegant, and unsatisfying. But it's a question of congruence:
     precision and flexibility may be just as disfunctional in novel,
     uncertain situations as sloppiness and vacillation are in familiar,
     well-defined ones. Those who admire the massive, rigid bone structures
     of dinosaurs should remember that jellyfish still enjoy their very
     secure ecological niche.
