Ever been frustrated by your office phone? Didn't know how to transfer? Teleconference? Browse the voicemail instead of listening to it sequentially?
There's a lot to be said for good design. Good design makes tasks simpler. Tools should make you look better at what you do, not intimidate you and frustrate you and embarrass you in front of others.
Rethink the tools in your office that cause you pain. How much would the company save if the design had been right the first time?
Just because people have become numb to it and accustomed to it doesn't mean it's right. Watch the newbies come into the office. It's less orientation than it is disorientation.
