PurposeThe complexity of succession in family firms is multifaceted and can sometimes lead to turbulence. While structured succession strategies offer a roadmap for smoother transitions, intergenerational differences in family small and medium-sized enterprises (SMEs) can lead to varied interpretations of an effective succession blueprint. This study synergizes the strategic entrepreneurship framework with the socioemotional wealth (SEW) perspective to probe into how formalized succession planning impacts performance in family SMEs. Furthermore, it delves into the mediating role of succession satisfaction, especially in family firms characterized by pronounced SEW and helmed by CEOs from different generational cohorts.Design/methodology/approachEmploying a comprehensive dataset from 1,833 global family businesses, this research utilizes bootstrapping regression models to discern the intertwined effects of mediator and moderator variables and their statistical significance.FindingsThe main findings suggest that succession satisfaction does matter for a good succession process and that succession plans work only in family firms with a high degree of SEW and that are led by older family CEOs (e.g. baby boomers).Practical implicationsThe results offer fresh perspectives on succession processes, with a particular focus on how to improve the satisfaction of millennial family CEOs.Originality/valueThe study uniquely combines strategic entrepreneurship and SEW to offer a holistic view of succession planning, highlighting satisfaction’s mediating role and SEW’s moderating influence. Additionally, it pioneers the incorporation of generational cohorts into the succession discourse.
