Heuristic Evaluation - Coggle Diagram

- - - - e.g. colorful circle - know system is thinking
  - - - Eliminate error-prone conditions or
        
        Drop down menu / calendar can constraint and prevent errors of entering dates
      - Check for them and present users with a confirmation option before they commit the action
  - - - making information appear in a natural and logical order.
  - - - Problem may arise when different developers develop them
    - - consistency throughout the same product
        
        same color, font, wording, template
    - - consistency with other products in its class
  - - - unseen by novice user
      - speed up interaction for expert user
      - System can cater to both inexperienced and experienced users
      - Allow users to tailor frequent actions
      - e.g. ctrl+c ctrl+v for experts
      - e.g. help video for novice, but expert can skip
  - - - e.g. help, question buttons
    - - easy to search
      - focused on user's task
      - list concrete steps to be carried out
      - not be too large
- - - - Briefing
      - Evaluation by each individual
      - Passes through the interface
        
        General pass
        
        Note obvious violations
        
        Second detailed pass
  - - - Aggregate findings into a single list of problems and the heuristics violated.
    - - allocate resources to fix problems and estimates of need for more usability effort
      - Combination of frequency, impact, and persistence
        
        Frequency
        
        Will the problem be common or rare
        
        Impact
        
        Easy or difficult for users to overcome
        
        Persistence
        
        One time that users overcome once they know about it, or repeatedly bothered, even if they know about it
      - done independently by all evaluators
      - make these ratings after you have completed the heuristic evaluation
      - 5 point scale
- - - - Cannot afford to hire lots of people
