We outline the place of fieldwork in comparative interpretive research. Detailed qualitative fieldwork is central to most interpretive research, but practical guidance on how to navigate the field remains rooted to the idiographic tradition. The presumption is one of sustained immersion in a discrete setting. Interpretive comparison, however, necessarily requires partial immersion across multiple sites in shorter, more interrupted bursts. We call this yo-yoing. Crucially, the researcher must be alert to the surprises and moments of epiphany that can challenge initial assumptions and open new possibilities. We seek here to develop and illustrate key ‘rules of thumb’ that will enable researchers to manage the challenges and maximise the opportunities.
