The evidence is out there. If you look at successful libraries and applications, they almost always gave well-defined design and architecture guidelines. In fact, I can’t think of a good software library out there that doesn’t have a solid design and architecture. On the other hand, I often see big piles of mud that have to be re-written over (and over), because people believe architecture takes too long or they believe it’s unnecessarily complex.
