I like this. I had a rule of three: figure out three qualitatively different ways to solve the problem - different in kind, not just in choice of tools. Once you have three you start to understand the trade-offs. And you can come up with others quite easily.

I like that as a process. Seeing the trade-offs is the key. I argue that engineering is all about trade-offs.
