A number of Enterprise 2.0 collaboration platforms are beginning to proliferate. By leveraging typical Web 2.0 attributes, these platforms provide enterprises with a collaborative environment to develop capabilities by collectively generating, sharing and refining business knowledge (including information, functionality and business processes). Deductively deriving from the assimilation literature stream, this article conceptually discusses a quantitative research model to constitute a deeper understanding of Enterprise 2.0 technology assimilation on an individual level. Our research contributes to the existing assimilation and adoption theory by integrating the social exchange theory as well as emphasizing the impact of Enterprise Mashup system assimilation towards changes in work processes. Furthermore, we include several object-related constructs like user perceptions about technology-specific aspects and work characteristics as well as moderator effects which are emphasized to have an impact on usage behavior of work-productivity systems and the resulting work processes.
