different from all the other bags of magic beans I've seen before.
Simple, the XP guys avoid "maintenance".
The real slowdown comes when you shift from clean slate development to
maintenance. I can write 100+ lines of code per hour when I start out.
However, then I start having to debug things. Suddenly, my lines of
code per hour drops like a stone.
Thus, my gripe about the C3 system the XP guys use as a "success". You
look really productive picking off the easy bits with a clean slate.
However, code spends most of its life in maintenance mode where you wind
up writing about 5 lines of code an hour because you have to think and
hunt for quite a while before you can even begin to code.
