Top Five Usability Blunders (And Fixes) (2006/01/06)


Five easy steps to alienating your users with bad usability

  1. Fail to simplify a comprehensive interface so that new users can quickly climb past the suck threshold.
  2. Build an inconsistent UI layout or interaction design that varies throughout the application, creating a sense of dissonance for the users.
  3. Interrupt the user’s workflow with pop-ups and other modal interruptions.
  4. Limit expert users to following “new user” workflow, one tedius, repetitive step at a time when shortcuts would work.
  5. Don’t suggest solutions when an error message is displayed.
