  1. 2.

    User Centered Design (UX) • UX is a rhetorically based

    philosophy of design that considers users’ needs and wants and limitations when designing a product. 2 If you don’t consider my needs and wants, then I won’t want to use your product.
  2. 3.

    Usability Testing (UT) UT is a method for finding out

    if a product works for users. 3 I feel the designers could make this product more convenient for me to use. You aren’t the user dummy. I am and it works fine for me as long as you aren’t around.
  3. 5.

    Effective • Are users successful when using the product? Often

    measured by how successful a user is in completing a task. 5
  4. 6.

    Efficient • Are uses able to accomplish what they want

    to do with the least waste of time or effort? Often measured in the amount of time or number of clicks or keystrokes it takes for users to complete tasks. 6
  5. 8.

    Error Tolerant • How tolerant is the product if users

    make an error when using it? Does the product help users recover from the error? 8
  6. 9.

    Easy to Learn • How easy is it for users

    to build their knowledge of how to use the product without deliberate effort? Sometimes referred to as a product being intuitive to use. 9

    Types of Usability Tests 10 • Lab based testing involves

    recruiting participants and observing their behavior as they do a series of tasks. Often involves video-taping the user and several observers. • Survey testing involves asking users of a product to respond to a series of questions about their user experience. • Cognitive walkthrough involves an evaluator who does a set of specific tasks rather than the actual user. The idea is for the evaluator to assume the role of user.
