Bertrand Meyer, one of the original OOAD people, suggested a step farther: split decisions from actions.

I really came to appreciate this while ramping up on test writing. Decisions are often trivial to decompose, reuse, and test. Actions not so much, and are sometimes defined by procedures in the literal sense.

Still, if you have facility with the English language or aren’t ashamed to use a thesaurus, meaningful method names and boundaries can help break a problem down and let someone zero in on a bug.
