Purpose - The purpose of the article is to analyze the different roles and natures of objects in organizational process. Furthermore, the concept of the mediation object is developed to understand how the objects help to structure interactions and collective activities over time.
Design/methodology/approach - The article employs data from a case study (the Pupitre Virtuel) in order to highlight and illustrate the relevance of a process analysis of the roles and natures of objects.
Findings - We demonstrate that the roles and natures of objects evolve over time through controversies and compromises. On the one hand, the evolution of interactions drives the evolution of the roles and natures of objects. On the other, the evolution of objects help the actors to structure their interactions and activities.
Originality/value - We argue that, rather than a static analysis, human-object interaction needs to be understood and observed through a process analysis, taking into account the evolution of objects and interactions. This article shows that mediation objects can play three roles - as carriers of controversies, of compromises, and of prescriptions - and that it can appear in one of three aspects - interpretable, modifiable, and non-interpretable/non-modifiable.
