  • 1. NCSU Libraries Rapid user testing with prototypes
    TRLN Annual Meeting – July 2010
    Susan Teague Rector & Angie Ballard
    1
  • 2. What we tested
    Do users navigate using the expected menu items?
    Do users pre-select tabs in a tabbed search box before entering search terms?
    How do users interact with tabbed or non-tabbed search results?

  • 3. Methodology
    Users were recruited in situ in the library lobby
    Navigation Testing
    Search Box Testing
    Users were asked to complete 4 of 15 tasks using a working prototype of navigation menus only.
    Each task required the user to open a navigation menu and indicate which menu item they would select to look for the specified information.
    Facilitators recorded up to 4 of each user’s menu selections, in order of selection.
    3
    Each participant completed 2 tasks using one of the 2 search models; many participants volunteered to answer more than 2 questions.
    Facilitators documented
    tab the participant initially selected
    search term(s) used
    path taken to complete the task,
    whether the participant used the default ‘All’ tab only, silos only or both.
    A facilitator assessment of task difficulty was recorded for both tests
  • 4. Test Setup

  • 6. Take Aways
    Rapid testing:
    Yields more feedback in less time.
    Best for testing specific features.
    Tests should last no more than 5 minutes.
    Saves resources for recruiting, scheduling, logistics, testing, and compensation.
    Does not save research planning & analysis time.

  • 7. Take Aways
    Informal test environment may mean more realistic user interactions with product.
    Results are somewhat skewed toward users who use the physical space.
    Should be balanced with results from other types of testing.
    Helps uncover areas for further testing.
