A Usage Model to Enrich MDSEA Approach

An information system supports the actors’ activities of an organization. Thus, the implementation of a new digital tool is a process of mutual transformation between organization and technology, involving changes on several 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 their work activities. Our work intends to support these changes to improve interoperability projects based on MDSEA approach and encourage so-called positive changes, while facilitating the implementation of new IT solutions. We propose to understand both the variability 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-centred 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.
