AbstractThe business value of information technology (IT) has been one of the top concerns of both practitioners and scholars for decades. Numerous studies have documented the positive effects of IT capability on organizational performance but our knowledge of the processes through which such gains are achieved remains limited due to a lack of focus on the business environment. Such a linkage therefore remains the subject of debate in the information systems literature. In this study, we fill this gap by investigating the mediating role of business process agility and the moderating roles of environmental factors. On the basis of matched survey data obtained from 214 IT and business executives from manufacturing firms in China, our analyses show that even though firm-wide IT capability presents the characteristics of rarity, appropriability, non-reproducibility, and non-substitutability, its impact on organizational performance is fully mediated by business process agility. Our results also show that the impact of the environment is multifaceted and nuanced. In particular, environmental hostility weakens the effect of IT capability on business process agility, while environmental complexity strengthens it. The theoretical and practical implications of this study, and its limitations, are also discussed.Keywords: IT capabilityorganizational performancebusiness process agilityenvironmental factors AcknowledgementsThe authors are grateful for financial support from Humanities and Social Sciences Foundation of the Ministry of Education of China (No. 10YJC630258, No. 10YJC630102), National Natural Science Foundation of China (No. 71273160) and Social Science Research of China (No. 12CGL053) for this project.Additional informationNotes on contributorsYang ChenAbout the AuthorsDr. Yang Chen is an associate professor in School of Business Administration, Southwestern University of Finance and Economics in China.
