The range of disciplinary approaches leveraged in implementing CSCW systems makes CSCW difficult to evaluate, measure, and generalize to multiple populations. Because researchers evaluating CSCW systems often bypass quantitative data in favor of naturalistic inquiry, results can be largely subjective due to the complexity and nuances of organizations themselves. Possibly as a result of the debate between qualitative and quantitative researchers, three evaluation approaches have emerged in the literature examining CSCW systems. However, each approach faces its own unique challenges and weaknesses:
