In this chapter, the authors outline how theorizing in family business research might benefit from combining qualitative case studies with quantitative methods (e.g., surveys, experiments, quantitative field studies) to provide ‘full-cycle’ research. First, they introduce full-cycle research approaches (that typically explain how researchers may move between qualitative theory-building methods and quantitative theory-testing methods) offered by organizational scholars. Next, through an examination of recent qualitative case studies in family business contexts, they identify some of the common questions these studies have answered and not answered. Based on this analysis, they suggest how research that combines qualitative case studies and quantitative methodologies might help family business researchers to more completely theorize phenomena of interest. In this way, they provide a set of exemplars for performing full-cycle research in the family business arena.
