The fundamental problem is that people don't like change. I've encountered this a few times. I invent a system process to make a work flow simpler, people resist because they don't want learn.

One key example was an intranet out of office board. The secretaries maintained a list of who was in or out (context: 13 years ago with very little good groupware). Engineers would sign out the scratch themselves off. Was it consistent? No. The system was very simple and engineers loved it. Did the secretaries? Nope. Did it get traction? Nope.
