When using the Top-Down approach to log results from user testing, place them under the following categories.

  1. Clarify the core concepts
    Does the design match the user’s mental model (e. g., the desktop metaphor)?
  2. Fit content to customers who use the product
    Does the content fit the user’s expectations? Is the information organized or mapped properly and at the right level for the audience? Are there any missing parts?
  3. Plan and maintain consistency
    Is there consistency from program to program (external consistency and within a program (internal consistency)?
  4. Provide reassuring feedback
    How does the system provide feedback or information to the user (dialog boxes, time to complete tasks etc.)’?
  5. Clarify interaction rules
    Does the system follow a standard set of rules For interacting with the product from a design point of view (e.g, drag and drop or buttons)?
  6. Structure navigation clearly
    Does the user understand how to get from point A to point B (menu, icon, keyboard use)?
  7. Use plain terminology
    Does the language match the user’s own vocabulary of use?
  8. Optimize user assistance
    Can users get help when they need it (on1ine help or performance support)?
  9. Optimize visual design
    Is the ‘visual design effective and pleasing (e.g,, do radio buttons look like radio buttons; are icons intuitive in design?
  10. Design for the context of use
    Can the product he used as designed (are there “bugs” in the system that prevent it or is the context of use poorly conceived
