While the concept of dynamic managerial capabilities was initially developed to understand top managers' strategic decisions, we theorize that it can explain how middle managers successfully contribute to functional outcomes. In this paper, we apply the dynamic managerial capabilities perspective and theorize that middle managers' capabilities to sense, seize, and reconfigure opportunities and assets, enhance product ambidexterity. We test our predictions with survey data obtained in two waves with a three‐year time lag and enriched with archival data from a sample of 185 German middle managers. Our results show that middle managers' general human capital (specialized education), structural social capital (managerial ties), and relational social capital (trust) are positively related to product ambidexterity, while their cognitive social capital (solidarity) is negatively related. We contribute by expanding the concept of dynamic managerial capabilities to middle management and provide insights into the underexplored relationship between middle managers' capabilities and functional product ambidexterity.

Although chief executive officers (CEOs) are the primary decision‐makers in their firms, there has been little research on how CEOs' decision styles affect firm performance. This study explores the relationships between firm performance and two key dimensions of CEO decision style, namely the use of heuristics and decision standards. We conceptualize the speed and innovativeness of new product development (NPD) as mediators in these relationships. An empirical analysis of 1046 German firms indicates that CEOs' use of heuristics may lead to higher NPD speed and stronger firm performance. In addition, higher decision standards, i.e., a stronger tendency to make the best decisions possible, among CEOs may promote higher NPD speed, NPD innovativeness, and firm performance but may also lead to less use of heuristics. Our findings underscore the relevance of CEO decision styles for firm performance and NPD, contribute to the debate on the rationality of heuristics, and conceptually broaden the role of decision standards in decision‐making.
