In this article, we explore the question of how membership, hierarchy, rules, monitoring, and sanctions are used at German professorships to organize research. Using these five criteria of an organization from Ahrne and Brunsson (Organization, 18(1):83-104, 2011) as a theoretical pattern, we shed light on the meso-level of universities in the German higher education system--the professorship. It is at this level that the collaborative production of research is organized. We show which organizational mechanisms are necessary for this joint production process, how the practical implementation and interpretation of rules as an organizational process take place at the professorships, as well as various negotiations and sanctions. In the German higher education system, professors are the superiors of their academic staff. The professor decides on the hiring and renewal of employees and is the supervisor of doctoral candidates, who in the German higher education system are mostly employed as research assistants. To illustrate the characteristics of the criteria, we draw on empirical material from mixed-methods research, which made it possible to contrast and substantiate the special features of professorships in Germany from different perspectives and data.
