This is one I learned the hard way. I made a number of much-needed fixes at a job where they'd never really had a dedicated technical person before. People freaked out. I hadn't communicated what I was doing and why it was necessary, and it took a while to earn goodwill after that. Lesson learned: don't implement a solution until you've convinced everyone they have a problem and this will fix it.
