Deciding on which frameworks to use and designing those frameworks are complicated tasks. In this paper we propose using the Task and Technology Interaction (TTI) model as a frame of reference for tackling these problems in the domain of Group Support Systems (GSSs). The TTI provides a set of three high level abstractions for determining fundamental invariants of the nature of technological support embedded in GSSs and an array of distinctions within each of the three abstractions that can be used for designing frameworks for GSSs
