This research focuses on analysing knowledge processes of the design process, especially the early phases of the design process that can be called concept design. It aims at developing a body of knowledge that builds on the relevant issues toward user‑centred design in a form of a framework. This is intended to apply, organise and synthesise processes, theories and concepts from the separate but linked disciplines of knowledge management and human‑ computer interaction, hence addressing one of the most essential topics and goals of system design, i.e. how to define what is needed in the system and how the system should mediate human activitiesÂ„for the purposes of this research, in the context of interest‑based communities and mobile technology. The framework is based on the following propositions: (1) The participants of design process include designers and users as actors, both of which are seen to possess knowledge needed toward successful design; (2) this knowledge is proposed to be context‑specific, hence being specific for certain users using certain technology; (3) for the user as well as for the design professional there are some things that are known but have not been articulated; and (4) the knowledge processes transforming tacit knowledge into explicit knowledge by users and designers are linked and need to be combined, finally (5) toward knowledge embedded into concepts, products, or services. Overall, the research highlights how knowledge processes enable user involvement and capturing tacit (and novel) user knowledge toward successful concept designdesign.
