Grounded in dynamic capabilities perspective, our study offers a model of IT outsourcing success. We distinguish between three sets of IT outsourcing capabilities. We first define IT outsourcing dynamic capabilities as the ability of an organization to purposefully extend, create or modify its information technology resources through an outsourcing arrangement. We define IT outsourcing operational capabilities as the ability of the client firm to manage/execute IT outsourcing arrangements. IT outsourcing learning capabilities are defined as the capacity to acquire external knowledge on IT outsourcing and accumulate experience. We theorize on the relationships between these capabilities and propose a model of their impact on IT outsourcing success. A cross-sectional survey of organizations across different industries will provide the data and a structural equation modeling (SEM) approach will be used to analyze the data.
