In this presentation, I will explore how usability testing has been used to spark changes in the design of the Northwest Justice Project’s new SharePoint content management system. Usability testing has become a popular user research method for assessing different aspects of a product, most commonly websites. By conducting usability tests early and often in your design process, many problems with the product can be targeted and resolved before a final design is released. Jackie Holmes will present on the basics of usability testing such as how to prepare tasks, what to look for during the test, how to analyze your observations, and how test results can influence design.
