On the tube on the way home, I read this article in which the author suggests rewriting the Highway Code as a set of principles rather than as a rule book. He goes on to argue that working from principles would lead to more consistent judgements. This article resonated with me because establishing architectural principles and communicating them is so important to the success of establishing an architecture within the enterprise. It is much more valuable to communicate and agree the principles rather than try to enforce the decisions based on them. There’s a couple of good overviews of architectural principles here and here.
