Before a strategy can be developed, the problem it is supposed to address needs to be formulated. We establish the microfoundations of strategic problem formulation by developing a theory that predicts a core set of impediments to formulation that arise when complex, ill‐structured problems are addressed by heterogeneous teams. These impediments fundamentally constrain and narrow problem formulation, thereby limiting solution search and potential value creation. We establish these impediments as a set of design goals, which, if remedied by an appropriately constructed mechanism, can expand problem formulation to be more comprehensive. Finally, we consider how organizations can improve problem formulation by creating a structured process that satisfies the theoretically derived design goals and detail a specific example of this mechanism (collaborative structured inquiry).

Numerous innovative applications have been developed to utilise large quantity of fly ash generated at coal fired thermal power plants (TPPs) worldwide. However, this requires power plants to undertake the role of third-party innovation intermediaries, that is, commercialising technological innovations developed by others. As commercialising an innovation requires considerable resources, a well-considered selection and promotion are desired. The paper presents a strategic framework for commercialisation of fly ash innovations. Explanation for step-by-step implementation and generic pointers for strategy formulation for typical problems are suggested. The proposed framework is expected to assist coal-fired TPPs in formulating strategies to commercialise innovative utilisation of fly ash. The study contributes to scarcely addressed aspects of an open innovation paradigm, that is, challenges faced by third-party intermediaries. 相似文献

Similarity judgments are an important and distinct aspect of strategy formulation. They are manifest in strategic decisions and errors, and in the construction of analytic concepts such as strategic groups and relatedness in diversification. However, existing models of strategy formulation either assume away the process of making similarity judgments or regard it as unproblematic. This paper highlights the role of similarity judgments in strategy formulation, and discusses cognitive findings showing that decision makers’ assessment of similarity is not free from bias. The cognitive findings help construct a new process explanation for a wide range of apparently isolated strategic errors. The process explanation is contrasted and integrated with traditional explanations based on imperfections in decision inputs. Finally, in light of the cognitive findings, the methods and assumptions of existing approaches in strategy formulation research to the construction of analytic concepts are reexamined. © 1997 by John Wiley & Sons, Ltd. 相似文献

本文从系统优化视角,针对增设集散中心的横向并购供应链网络整合策略,利用变分不等式建立了随机需求下的整合优化模型。以市场链为主线,以供应链网络均衡理论为基 础,构建了以横向并购供应链网络活动总成本最小为目标的数学模型,通过转换成变分不等式采用改进的欧拉算法进行模型求解。通过数值算例进一步说明了模型的适用性和灵活性,得出了增设集散中心的并购整合策略能够降低供应链网络的平均运营成本的结论,通过对比不同市场紧密程度下产生的供应链网络平均成本协同效应,发现随着市场紧密程度的增加其协同效应更明显,为横向并购供应链网络整合优化提供理论依据与方法。 相似文献
