Abstract
In this paper, we propose a resource-based model to explain how expert systems generate sustained competitive advantage for a firm. Speciftcally, we analyze the extent to which expert systems (ESs) exhibit the attributes of value, rareness, imperfect imitability, and non substitutability associated with a rent-generating resource (e.g., Barney, 1991). Then, we discuss how expert systems yield sustainable competitive advantage through fostering organizational knowledge development and utilization. Finally, we examine the role of ESs in engenden’ng a reciprocal, mutually enhancing relationship with organizational competencies, leading to sustained competitive advantage. Propositions are ofleered to facilitate future research.
