Participatory design as one of the current approaches in the design research emerged with the demand for democracy at the intersection of the political agenda of the period and the dissemination of the technological infrastructure at workplaces. The participatory approach, first included in the design processes of the information systems, continued its existence as different practices focused on distinctive concerns due to its multidimensional structure that covers issues in political, economic and theoretical perspectives. The variety due to naming deficits of different practices and additional naming for the same practices have caused confusion in participatory design practice and terminology. The study aims to clarify this complexity by classifying the diversity which is the underlying causes of confusion. In this sense, the context of participation and the application areas of design were examined and the conditions that constitute the basis for different practices were investigated by literature review. According to their contextual dfferences, these different practices, grouped under collaborative design, open design and agonistic approach, were subjected to document analysis as projects. Content analysis categories are the variables taken from the evaluation framework set out in the previous section. As a result of this evaluation indicating the differences in the practices of the three approaches, both the classification was clarified and the effects of the contextual changes on the practices were put forward. Thus, while the results of the evaluation clarify terminology and practice, the evaluation framework guides the designer by emphasizing the points to be considered in practice.
