NCSU Libraries: Rapid user testing with prototypes

  1. 1. NCSU Libraries Rapid user testing with prototypes <ul><li>TRLN Annual Meeting – July 2010 </li></ul><ul><li>Susan Teague Rector & Angie Ballard </li></ul>
  2. 2. What we tested <ul><ul><li>Do users navigate using the expected menu items? </li></ul></ul><ul><ul><li>Do users pre-select tabs in a tabbed search box before entering search terms? </li></ul></ul><ul><ul><li>How do users interact with tabbed or non-tabbed search results? </li></ul></ul>
  3. 3. Methodology <ul><li>Users were asked to complete 4 of 15 tasks using a working prototype of navigation menus only. </li></ul><ul><li>Each task required the user to open a navigation menu and indicate which menu item they would select to look for the specified information. </li></ul><ul><li>Facilitators recorded up to 4 of each user’s menu selections, in order of selection. </li></ul><ul><li>Navigation Testing </li></ul><ul><li>Search Box Testing </li></ul><ul><li>Each participant completed 2 tasks using one of the 2 search models; many participants volunteered to answer more than 2 questions. </li></ul><ul><li>Facilitators documented </li></ul><ul><ul><li>tab the participant initially selected </li></ul></ul><ul><ul><li>search term(s) used </li></ul></ul><ul><ul><li>path taken to complete the task, </li></ul></ul><ul><ul><li>whether the participant used the default ‘All’ tab only, silos only or both. </li></ul></ul>A facilitator assessment of task difficulty was recorded for both tests <ul><ul><li>Users were recruited in situ in the library lobby </li></ul></ul>
  4. 4. Test Setup <ul><ul><li>Used candy bars as incentives </li></ul></ul><ul><ul><li>2 laptops with browsers open to prototype </li></ul></ul><ul><ul><li>Cycled through 15 tasks; 2-4 tasks per user in five minute sessions </li></ul></ul>D. H. Hill Lobby
  5. 5. Response Rate <ul><li>Total of 32 participants in 2 hours </li></ul><ul><li>24 Undergraduates </li></ul><ul><li>3 Graduates </li></ul><ul><li>2 Staff </li></ul><ul><li>1 Visitor </li></ul><ul><li>2 Library Staff Members </li></ul><ul><li>Total of 28 participants in 4 hours </li></ul><ul><li>22 Undergraduates </li></ul><ul><li>3 Graduates </li></ul><ul><li>2 Library Staff Members </li></ul><ul><li>1 Non-Traditional Student </li></ul><ul><li>Navigation Testing </li></ul><ul><li>Search Box Testing </li></ul>
  6. 6. Take Aways <ul><li>Rapid testing: </li></ul><ul><li>Yields more feedback in less time. </li></ul><ul><li>Best for testing specific features. </li></ul><ul><li>Tests should last no more than 5 minutes. </li></ul><ul><li>Saves resources for recruiting, scheduling, logistics, testing, and compensation. </li></ul><ul><li>Does not save research planning & analysis time. </li></ul>
  7. 7. Take Aways <ul><li>Informal test environment may mean more realistic user interactions with product. </li></ul><ul><li>Results are somewhat skewed toward users who use the physical space. </li></ul><ul><li>Should be balanced with results from other types of testing. </li></ul><ul><li>Helps uncover areas for further testing. </li></ul>
