Human resources and sustained competitive advantage: a resource-based perspective

This paper integrates the theories and findings of micro-level organizational behaviour/human resource management research with the macrolevel resource-based view of the firm, specifically presenting a firm's human resources as an important potential source of sustained competitive advantage. Unlike practice-oriented discussions that assume the role of human resources as a source of sustained competitive advantage, we use the theoretical concepts from the resource-based view of the firm (Wernerfelt, 1984; Barney, 1991) to discuss how human resources meet the criteria for sustained competitive advantage in that they are valuable, rare, inimitable and non-substitutable. The implications for developing human resources as a source of sustained competitive advantage are discussed, particularly examining the role of HR practices and managers in this process.
