Pick any two small businesses in the same niche. Grow them for three or four decades. How identical do you think their evolved business practices will be? My very very naive take is that they will have had to solve similar problems over time and will have practices and systems that work analogously. I would bet they will probably not use identical software packages or data structures and will have had little reason to structure their internal operations around someone else's standards. This is especially likely to be true of standards that came along well after the companies already solved the problems the standards are aimed at.
