The experience described in this paper is being developed in the framework of the PALETTE1 project by two teams of researchers involved in collecting information from some Communities of practice2 (CoPs) then in providing this information through suitable formats to their technical partners in the aim of designing an interoperable and extensible set of innovative services and specific scenarios to be implemented and validated in CoPs of diverse context (teaching, management and engineering domains). The aim of our paper is to describe and analyse the methodology created and applied to support this process. Implementing a Participatory Interview Process The participatory design process for the whole project was implemented following an Actor-Network Theory (ANT) [Latour, 1999; Monteiro, 2000] driven perspective.
