Top 10 Application Design Mistakes

20 Feb 2008 (Wed)

LATEST ALERT from usability guru Jakob Nielsen: A list of 10 usability violations that are both particularly egregious (conspicuously bad or offensive) and often seen in a wide variety of applications:

  1. Non-Standard GUI Controls
    1.a. Looking Like a GUI Control Without Being One
  2. Inconsistency
  3. No Perceived Affordance
    3.a. Tiny Click Targets
  4. No Feedback
    4.a. Out to Lunch Without a Progress Indicator
  5. Bad Error Messages
  6. Asking for the Same Info Twice
  7. No Default Values
  8. Dumping Users into the App
  9. Not Indicating How Info Will Be Used
  10. System-Centric Feature

 

Useful note: “Application usability is enhanced when users know how to operate the UI and it guides them through the workflow. Violating common guidelines prevents both… Usually, applications fail because they (a) solve the wrong problem, (b) have the wrong features for the right problem, or (c) make the right features too complicated for users to understand.”
