Critique

Critique

1. collaborative deconstructions of what makes a design successful and what makes it fail

2. two-way

   • designer articulating the rationale for their decisions and the critic responding to those judgments

3. engage deeply

4. divergent and convergent

5. can be abusive

   • to avoid: the “hamburger” rule; if you’re going to say something sharply negative, say something genuinely positive first

6. Socratic questioning

   • Clarification questions
   • Questions that challenge the designer’s assumptions
   • alternative perspectives questions
   • implications and consequences questions

7. isn’t just about method, but also expertise

   • expertise in the domain is important
   • participant response bias: have someone that is impartial to receive the feedback

8. Design principles

   • Intuitive
   • User-friendly
   • Simple
   • Novel
   • Powerful
   • Invisible
   • Universal
   • Just

9. Observation; requires Empirical Methods

   • Usability Tests
     • task-based evaluation
     • discover breakdowns
     • find stakeholder representative
     • define tasks that achieve the goal
     • think aloud
     • retrospective interview
     • can't tell if r design is useful
   • Technology Probes and Experience Sampling
     • ecological validity
     • test with high fidelity prototype
   • A/B Tests
     • remote experiment
     • A represents "control” condition; B represents “experimental” condition.
     • strong evidence of evidence of causality
     • limitation: difficulty of measuring meaningful things

10. Analytical Methods

    • Heuristic evaluation
      • idea: learnable by new user?
      • user interfaces should always make visible the system status
      • real world match
      • User control and freedom
      • Consistency and standards
      • Error prevention
      • Recognition versus recall
      • Flexibility and user efficiency
        • offer help and documentation
      • Help users diagnose and recover from errors
        • minimalist design
    • Walkthroughs
    • Claims analysis
    • Cognitive Walkthrough
      • Select a task to evaluate
      • Obtain a prototype
      • multiple personas of representative
      • systematic and granular
