In this chapter, we discuss an evaluation of a computerized information system in an elderly care unit. The evaluation is based on the concept of actability, which is a combination of theories from Human-Computer Interaction and the Language Action Perspective. The reason for uniting different theories is to obtain a more holistic evaluation model. The findings show that the evaluated system has a low degree of actability, and the users had a positive attitude towards the system. One explanation could be that we, as evaluators, reviewed both structure and content, whereas the users saw only the content of the information system (i.e., its functions) as the most important aspect.
