Inquiring systems theory (Churchman, 1971), cognitive mapping (Lee, et al., 1992) and hermeneutics (Boland, et al., 1994) have provided the basis for systems to support organizational learning, distributed cognition, and knowledge management. Boland, et al. (1994) describe three entities in such systems and six principles for their design. Richardson (2005) argues that communication is neglected element in these systems and integrates Habermas’s (1984, 1985) theory of communicative action, specifically discursive action, to develop revised design principles. This paper describes DISCOMAP, a system that instantiates and tests the revised design principles using discussion forums and The Planners Laboratory©, a new software package that provides advanced modeling, graphical and network capabilities to provide shareable models with engaging visual interfaces for decision makers.
