The presentation introduces the concept of wicked problems and their application to library user experience design. It defines wicked problems as having no clear definition or solution, with ongoing consequences. Ten key characteristics of wicked problems are outlined. The presentation then discusses approaches to resolving wicked problems, including authoritative, collaborative, and competitive methods. A case study of redesigning a library website is used to illustrate how it posed a wicked problem with conflicting stakeholder perspectives. The presentation concludes by arguing the wicked problems model can change how user experience practitioners approach defining success and solutions.
