  3. Produce useful documents to help with design thinking
Design
  1. Generate dozens of ideas or paper interfaces
  2. Develop interactive paper prototype
  3. Test the prototypes quickly, iterate on the ones that have value, evaluate and combine the best parts into a converged solution: open card sorting, tree test, trigger word elicitation, swap sort and online card sorting, cognitive walkthrough, word list.
  4. Electronic prototype: using one tool throughout.
  5. Iterative process
Evaluation throughout the design process
  1. Qualitative and quantitative data
    Collect qualitative data to identify usability problems, then use quantitative survey to make predictions and measure the usability of a system
  2. Word list
    Can be both qualitative (circle words from a checklist of adjectives) and quantitative (Use word cloud or count the positive/negative comments).
  3. Card sorting
    Tree test, function familiarity test
  4. Cognitive walkthrough
    A happy path and 4 questions interview to identify usability problems.
  5. Usability testing software: Morae, Silverback
  6. Questionnaires: AttrakDiff
  7. Create and present a clear series of next steps
