This study examines the post adoption of technology and explores why technology may not be sustainable in organizations after its deployment. In contrast with previous studies, which emphasize technology improvement, users’ post-adoptive behavior, and organization adaptation, this research offers a practice-based analysis and suggests that architectural innovations may bring about a fundamental transition in organizational practices and collaboration patterns. This transformation in organizational principles renders technology obsolescence, and precludes a superficial change in technological features. This case study analyzes an e-procurement system deployed from Taiwan to China and investigates why the initial success of technology use was not transferred to the later application. The technology use within supply chain migration provides a useful context to understand problems of technology sustainability. Important implications are provided to enhance the theoretical development of post technology adoption. Practical insights are discussed with regard to supply chain changes.
