The care information system PIK--the fit between user and system.
OBJECTIVE
The presented laboratory study explores the relationship between the care information system PIK and its users, focusing on intuitive program usage, occurring errors, the usefulness of the evaluation method, and the role of person related variables.


METHODS
Three studies were conducted. While thinking aloud, a sample of 26 participants performed certain tasks, which were recorded in protocols. In addition, the occurring errors were rated in an error taxonomy.


RESULTS
While the actual use of the program proved quite easy, conceptual structuring caused the participants difficulties. These difficulties stemmed mainly from problems encountered in generating a clear mental picture of the system, and the consequences of the actions. Over time, the program showed a positive development.


CONCLUSIONS
Discussion of the results focuses on implementation processes in the context of usability research. The need to train users in the conceptual structure of the program and to build realistic expectations are the focus of our outline.
