This was actually not the conclusion I was expecting:<p>> Don't bother improving your product unless it results in visible changes the user can see, find, and hopefully appreciate.<p>I couldn't disagree more strongly. I can't think of the last time I encountered a UX change I thought was actually worth it. They're always bothersome, because now I <i>notice the tool</i>--it's no longer an extension of my mind and body, instead all of a sudden it's something getting in the way of my work.<p>I claim there are two reasons UX changes happen:<p>(1) Original design was delivered too hastily and was flawed, requiring breaking changes in the field to fix it.<p>(2) Someone wants to get promoted and thinks the best way to do that is to spin a "UX refresh" as something "successful" rather than the signal of abject failure it actually is. We should stop rewarding this behavior.
