Scholarly interest in how managers make strategic decisions dates from the inception of the strategic management field and continues in the present. Although such decision-making was originally conceived as a completely rational, top-management process, contemporary thinking recognizes that strategies from across multiple organizational levels change within social and political contexts. Within this broad domain, multiple research streams address a wide variety of topics and issues. Prominent among these are, (1) the extent to which strategic decisions are formed through comprehensive analysis versus piecemeal decision-making, (2) how characteristics of top managers and the composition of top management teams affect strategic decision-making, (3) the role of politics, conflict, and consensus in strategy making, (4) how cognitive biases and heuristics influence the process, (5) when and how intuitive judgments can form the basis for effective decision-making, and (6) how managers at various organizational levels participate in the process. Research across these streams is both descriptive and normative, with a focus on contextual contingencies and relationships to firm performance. Taken as a whole this literature has significantly enhanced understanding of how strategies form within organizations. Contemporary work continues to provide new insights and demonstrates the continued value of this productive area of study.
