Research design and methodology

External actors’ sensemaking processes concerning policy concepts and their translation into field practices under conditions of competing demands are a complex phenomenon. Hence, a single case study is presented, which allows for an in-depth engagement with research participants’ perspectives and contextual conditions (Yin, 2013). Four external actors are explored individually as well as from a comparative perspective, in order to gain insights into similarities and disparities and to make inferences with regard to the overall research question (Mills et al., 2010a, p. 135f).
