I was reminded of the real power of OO based systems and good object design yesterday. Taking a whole series of already-written classes, I was able to bolt together a new application based on the same data in just a few lines of code and get it running on a website too. The real saving comes
not in the early development, but rather in the ongoing reuse.
"Design Matters".
