“…As Frank Knight pointed out, the existence of (entrepreneurial) judgement is essential to the existence of firms (Langlois and Cosgel, 1993;Jacobides and Winter, 2006). Such entrepreneurial qualities may be important in both the creation of new capabilities and the recombination of existing ones and also in the creation, design, and effectuation of new "strategic architectures" or business models for the firm.Through the detailed analysis of capabilities, their architecture, and their interactions, we can examine how the firms' structure allows it to canalize its expertise and develop new knowledge, products, or markets (Galunic and Eisenhardt, 2001;Helfat and Eisenhardt, 2004;Williams and Mitchell, 2004). This can help us better understand how firms adapt to change and also consider how the mechanisms at the architectural level compare and contrast with the operation of a firm's senior management.…”
