Case studies as a research method are drawing increasing interest from social sciences and humanities researchers, but they pose challenges regarding the ability to generalize and make conclusions that can be applied to other cases. Is it possible to generalize the results of one case, and to apply them in other cases that have not been studied? To answer this, several advocates of qualitative research have developed "in-case" analysis methods that enable inference and respond to critics of the case study method. One of the notable contributions from the evolution movement was what researchers called "Process Tracing." This study aims to consider the methodological contribution that this "tracing" has made to qualitative research related to the case study method in the social sciences. The paper is motivated by the new methodological contributions of the Process Tracing, which have taken qualitative research, especially the case study method, to new horizons.
