10 Fundamental Rules for the Age of User Experience Technology

  • More features isn’t better, it’s worse.
  • You can’t make things easier by adding to them.
  • Confusion is the ultimate deal-breaker.
  • Style matters
  • Only features that provide a good user experience will be used.
  • Any feature that requires learning will only be adopted by a small fraction of users.
  • Unused features are not only useless, they can slow you down and diminish ease of use.
  • Users do not want to think about technology: what really counts is what it does for them.
  • Forget about the killer feature. Welcome to the age of the killer user-experience.
  • Less is difficult, that’s why less is more
