Information systems development (ISD) projects are highly complex, with different groups of people having to collaborate and exchange their knowledge. Considering the intensity of knowledge exchange that takes place in outsourced ISD projects, in this study a conceptual model was developed, aiming to examine the influence of four antecedents, i.e. standardization, requirement volatility, internal integration, and external integration, on two dependent variables, i.e. process performance and product performance. Data were collected from 46 software companies in four big cities in Indonesia. The collected data were examined to verify the proposed theoretical model using the partial least square structural equation modeling (PLS-SEM) technique. The results show that process performance is significantly influenced by internal integration and standardization, while product performance is significantly influenced by external integration and requirement volatility. This study contributes to a better understanding of how knowledge integration can be managed in outsourced ISD projects in view of increasing their success
