In this week's podcast, Brian Christiansen and I explore usability techniques for web-based applications. Web-based applications are different from content-based web sites because the users are involved in a transaction. When we're researching the usability of a content-based site, we're focused on how users will find and react to the information. However, with web-based applications, there are many other considerations that we need to account for. Because this is a big topic, we've divided it into two podcasts. In Part 1, Brian and I lay down the framework for what our usability research needs to tell us about our web-based application. In Part 2, will look at the techniques for finding that information.
