Expanding into new product areas is an important part of the growth strategy of many firms, but there is still more to learn about how it affects firm performance. We believe that as the top management team ( TMT ) is responsible for coordinating product expansion, looking there can yield valuable clues. We argue that diversification entails significant additional information processing and that this strains top managerial resources. We hypothesize that task‐related faultlines within the TMT may help it cope with product expansion while bio‐demographic faultlines may hinder it. We find support for these hypotheses on a longitudinal sample of 2,730 expansion steps made by 61 German firms between 1985 and 2007: task related faultline strength increases performance when diversifying, while bio‐demographic faultline strength decreases it .
