This research in progress proposes to look at end user participation (EUP) in the system development life cycle (SDLC) through the dual lenses of Representation Theory and shared affordances. It is known that EUP results in increased end user satisfaction of the information system (IS), yet using EUP during the SDLC remains uncommon. Should EUP occur throughout the SDLC an IS may be developed that converges on a faithful representation of the shared affordances required for all stakeholders, specifically the end user. Effective use is understudied, and this research further delineates between use and effective use. With a better understanding of the impediments to EUP during the SDLC it may be possible to develop antidotes to increase participation and hence success rate.
