Is dogma really useful? No matter how sensible some strategy is, can we afford to treat it as an absolute truth? I get the feeling that we are all inclined to think that we have the entire story of development in our own personal heads and can therefore lay down laws. ...and yet most of these disciplines need everyone's co-operation and one can feel that if you don't treat it as dogma then you're never going to make everyone "comply"... I think the fact that TDD (and other popularly debated methodologies) haven't taken over just by being obviously easier and better is a sign that they aren't really suitable for being made into dogmas. They're tools and we should have the choice like any workman to choose them or not.
