Usable Products conducted multiple suites of usability testing before and after the launch of D&B's Small Business Solutions web site in 2001 and 2002. The iterative testing strategy enabled D&B to track customer experience as the site evolved through the addition of new functionality.
D&B engaged Usable Products to design new functionality for the Search user interface. Usable Products also was engaged for iterative usability testing when improvements to D&B's eBIR (electronic Business Information Report) product were introduced.
UPC discovered through user testing that many searches were initially performed in Arkansas. Note the default entry in theState/Prov field.

Based on our suggestions, the state selector was repositioned and the last state used was selected automatically.
|
Two issues with this design were discovered in user testing: 1) the user interface did not draw attention to the new dual search modes feature. 2) Identifying and switching between modes was difficult.
|
|
The radio buttons of the previous design was replaced by a tabbed user interface. In user tests this interaction proved to be more successful at drawing attention to the added functionality and indicating which type of search was being conducted.
