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