Organizations do not operate in a vacuum. Conditions and trends of the external environmental are pivotal as they shape the environment in which firms operate. Family businesses create a distinctive setting compared to non-family businesses as two systems can be distinguished, the family and the business, which are both embedded in the larger environment. Through family participation in management and ownership positions, the family is the dominant coalition in the firm. Research has shown that characteristics of the dominant coalition affect firm behavior and outcomes (Hambrick and Mason, 1984). In family firms, this implies that the family system resonates within the business system. A family, with its own structure, dynamics, and values and norms, has a large influence on the business. Nevertheless, there is little understanding of how the family system affects the business. In addition, while the organization is not immune to changes in its environment, neither is the family. The family is embedded in society and consequently, societal trends alter family structure and dynamics. Given the intertwinement of the family and the business, changes in the family system are expected to have implications for the family business. Implications of family involvement may alter due to a change in family structure, events, and dynamics. Thus, when looking at important future issues for family business research, the family system cannot be overlooked. The purpose of this chapter is to map important changes in the family and their implications for family businesses. This chapter is structured as follows. Firstly, the nature of the family system is explicated. Subsequently, significant trends in the family system and their implications in terms of management, ownership, and succession for family businesses are addressed. The chapter ends with concluding remarks and directions for future research (Table 1.1).
