Top management team diversity and ambidexterity: The contingent role of shared responsibility and CEO cognitive trust

Earlier research has suggested that diversity is a double-edged sword when achieving organizational ambidexterity. While it may contribute to the development of new combinations of exploration and exploitation, it may also lead to disagreements and potential conflict within top management teams (TMTs). To improve our understanding of the effectiveness of diversity in ambidextrous organizations, we develop a synergistic perspective on TMT diversity and examine how two types of diversity - functional and age diversity - affect the achievement of organizational ambidexterity. We also identify shared responsibility and CEO cognitive trust as important contingencies that may complement the effects of diversity within TMTs in terms of resolving potential conflicts and managing tensions between exploration and exploitation effectively. Based on multisource data, our study shows that CEO cognitive trust and shared responsibility moderate the relationship between different types of diversity and ambidexterity. Our study has important implications for research on organizational ambidexterity, diversity, and senior leadership. (C) 2017 Elsevier Ltd. All rights reserved.
