How E-commerce Succeeds: The Role of Information Systems in Boosting Customer Satisfaction

The rapid growth of e-commerce has revolutionized consumer behavior, especially among Millennials and Generation Z, who increasingly rely on online platforms for their purchases. This paper shows the impact of information systems success on individual performance outcomes in e-commerce, focusing on the DeLone and McLean information system success model and its three key dimensions: system quality, information quality, and service quality. A quantitative survey method was employed to gather data from e-commerce users in the western province of Sri Lanka, which is an economically developed region where Millennials and Generation Z are highly engaged with international and local e-commerce platforms. The study uses PLS-SEM to identify that system, information, and service quality significantly increase customer satisfaction and thereby improve individual performance in e-commerce. The study will address the significant research gap in Sri Lanka, where the rapid growth of e-commerce has not been adequately studied in terms of the impact of information and individual outcomes.
