This article examines the relationship between firm resources and product innovation performance (PIP) from a resource-based view (RBV). It classifies firm resources into six categories: physical, reputational, organizational, financial, human/intellectual, and technological. The RBV predicts that intangible resources like these will be important determinants of firm success. The article aims to determine which resources contribute most to PIP among Malaysian small and medium enterprises (SMEs). A survey of SMEs found that intangible resources like human/intellectual assets had a stronger relationship with PIP, consistent with expectations of the RBV.
