Research summary: This study examines the abandonment of organizational practices. We argue that firm choices in implementing practices affect how firms experience a practice and their subsequent likelihood of abandonment. We focus on utilization of the practice and staffing (i.e. career backgrounds of managers), as two important implementation choices that firms make. The findings demonstrate that practice utilization and staffing choices not only affect abandonment likelihood directly but also condition firms' susceptibility to pressures to abandon when social referents do. Our study contributes to diffusion research by examining practice abandonment—a relatively unexplored area in diffusion research—and by incorporating specific aspects of firms' post‐adoption choices into diffusion theory. Managerial summary: When do firms shut down practices? Prior research has shown that firms learn from the actions of other firms, both adopting and abandoning practices when their peers do. But unlike adoption decisions, abandonment decisions need to account for firms' own experiences with the practice. We study the abandonment of corporate venture capital (CVC) practices in the U.S. IT industry, which has experienced waves of adoption and abandonment. We find that firms that make more CVC investments are less likely to abandon the practice, and are less likely to learn vicariously from other firms' abandonment decisions, such that they are less likely to exit CVC when other firms do. Staffing choices also matter: hiring former venture capitalists makes firms less likely to abandon CVC practices, while hiring internally makes abandonment more likely. Plus, staffing choices affect how firms learn from the environment, as CVC managers pay attention to and learn more from the actions of firms that match their work backgrounds; i.e., firms that staff CVC units with former venture capitalists are more likely to follow exit decisions of VC firms, while those that staff with internal hires are more likely to follow their industry peers. Our results suggest that firms wanting to retain CVC practices should think carefully about the implementation choices they make, as they may be inadvertently sowing seeds of abandonment.
