Team projects are nowadays common practice in HCI education. This paper focuses on the role of clients and users in team projects in introductory HCI courses. In order to provide projects with a realistic context we invite people from industry to serve as clients for the student teams.

Another way we make projects realistic is to have teams evaluate their designs with real users. We describe how we incorporate the role of clients and users in our courses and describe our experiences.
