So let’s start by talking about extreme programming (XP). As I understand it, one of the major components of XP is “relentless refactoring.” My approach to solving problems has always been the same:

• First, break big problems into increasingly smaller problems
• Second, solve the small problems one at a time

My own term for this was “incremental” programming. As it turns out, I was ahead of my time and did not even know it.
