The article focuses on the methodological specifics of qualitative sociological studies commissioned by public administration authorities which aim to provide solutions to specific problems defined by the client. In conducting this kind of study, the researcher is expected not only to describe and understand the existing state of affairs but also to provide a set of recommendations for amending it. The research terrain is not defined by the sociologist herself but basically by the client. This situation reveals a series of (...) methodological and epistemological issues. The article discusses some of them and proposes that the research strategy of heuristic investigation may be an answer to the associated dilemmas. The author argues that the correct use of reflexive methodology can help the researcher to overcome the limits imposed on the research by the client’s presence and even make the apparent disadvantages work for her.
