@jasongorman Thanks for the further hints, but this is not quite what I'm after. What I'm looking for is an artifact of whatever form that I can give to developers to make them see the strategic view of what a system is expected to evolve into. But it would have to be something that these people actually read willingly - and that's the real issue here.

I had some success in my current project by basically writing a book in Douglas-Adams-adjacent tonality, but that was too much work...
