A usage model to enrich MDSEA approach
Résumé
An information system supports the actors’ activities of an organization. Thus, the implementation of a new digital tool is a process of mutual trans-formation between organization and technology, involving changes on sev-eral dimensions. More specifically, its implementation has an impact on the practices of the actors, resulting in significant changes that can be "positive" and/or "negative" for the actors and the work activity. Our work supports these changes to improve interoperability projects based on MDSEA ap-proach and encourage so-called "positive" changes, while facilitating the im-plementation of new IT solutions. We propose to understand both the varia-bility of organizational change and the tool enhancements. Thus, we propose a usage model to characterize individuals’ "usages" and their variability and show that this model only makes sense if it fits into a broader, user-centered approach to explore existing, potential and desired practices. We illustrate the implementation of the model and its ability to represent usage cases of a home care structure digitizing the care record.
