Abstract
The paper elaborates on the design and use of cross-organization virtual community spaces facilitating knowledge-based collaborative engagement in the practice of a boundary spanning alliance. Our approach builds upon the concept of transformable boundary artifacts and advances a perspective upon their design as first class objects in common information spaces. Using a case study on vacation package assembly, we identify offline elements of practice and discuss the components of an interaction vocabulary devised to facilitate their transformable interactive embodiment. Transformations allow boundary artifacts to exhibit plasticity as they transcend different social worlds and computing contexts within the cross-organization virtual community space, which in turn, forms the virtuality through which members make sense of collaborative work and contribute to a shared mission. Such contributions are materialized through recurrent interactions with different versions of boundary artifacts, which remain consistent and synchronized at all times.
