Since the earliest days of strategic management research, scholars have sought to measure and model the effects of top managers on organizational performance. A watershed moment in this effort came with the 1984 introduction of Hambrick and Mason’s upper echelon view and their contention that firms are a reflection of their top management teams (TMT). An explosion of research followed and hundreds, if not thousands, of manuscripts have since been published on the subject. While a number of excellent reviews of this extensive literature exist, a relative few have asked questions about the overall state and future of the field. We undertook this assessment in an effort to answer some key questions. Are we still making progress on the big questions that gave rise to the upper echelon view, or have we reached a point of diminishing returns with this stream of research? If we are at an inflection point, what are the issues that should drive future inquiry about top management teams?
