Abstract Despite the extensive proliferation of Information Technology Outsourcing (ITO), firms often obtain unsatisfactory outsourcing outcomes due to the lack of appropriate outsourcing capabilities of a client or their vendor. ITO clients strive to enhance outsourcing performance by establishing their own outsourcing capabilities as well as contracting with capable vendors to meet their strategic needs. Thus, for the success of an ITO project, it is imperative to find an effective combination of complementary outsourcing capabilities on both sides. However, knowledge of how to identify and develop a set of appropriate outsourcing capabilities of both client and vendor has yet to be developed. This study aims to fill this knowledge gap by elaborating on the configurational mechanisms of outsourcing capabilities from a bilateral perspective, which explicate how multiple types of client and vendor outsourcing capabilities combine into configurations simultaneously to produce high ITO performance. First, based on the ITO literature, we develop a conceptual framework that identifies three key types of outsourcing capabilities. Then, with the matched dataset collected from a client and their vendor, we conduct a fuzzy-set qualitative comparative analysis (fsQCA), which is a set-theoretic configurational method to investigate the systemic and holistic interdependencies among key outsourcing capabilities that produce high outsourcing performance. On the basis of the conceptual framework and empirical findings, we present four viable propositions to build configurations of client and vendor ITO capabilities that can achieve ITO success with theoretical and practical implications.

外包能力的一致模式：双边视角

摘要尽管信息技术外包（ITO）激增，但由于客户或其供应商缺乏适当的外包能力，企业常常无法获得令人满意的外包成果。ITO客户通过建立自己的外包能力以及与有能力的供应商签约以满足其战略需求，努力提高外包绩效。因此，为了成功完成ITO项目，必须在双方之间找到互补的外包能力的有效组合。但是，关于如何识别和开发一组适当的客户和供应商外包能力的知识尚待开发。这项研究旨在通过从双边角度阐述外包能力的配置机制来填补这一知识空白，这说明了如何将多种类型的客户和供应商外包功能同时组合到配置中以产生较高的ITO性能。首先，基于ITO文献，我们开发了一个概念框架，该框架确定了三种主要的外包能力类型。然后，利用从客户及其供应商处收集的匹配数据集，我们进行模糊集定性比较分析（fsQCA），这是一种集理论配置方法，用于研究产生高外包量的关键外包能力之间的系统性和整体性相互依赖性。性能。根据概念框架和实证结果，我们提出了四个可行的建议，以构建客户和供应商ITO功能的配置，这些配置可以实现ITO成功，并具有理论和实践意义。
