As markets become more turbulent, dynamic, and competitive, and as customers become more sophisticated and demanding, the scope of capabilities and resources needed to meet customer needs, wants, and desires are less likely to be found in any one firm. Instead, firms must develop strong collaborative capabilities. Though the benefits of interfirm collaboration for focal firms (the firms responsible for the final offering) and suppliers are reasonably well understood, effectiveness and efficiency in collaboration remain elusive for many firms. It is likely that the collaborative capabilities of both focal firms and key suppliers contribute to effective collaboration, and that the collaborative capabilities of focal firms may influence the collaborative capabilities of suppliers, which in turn influence product-market outcomes. This dissertation proposes an integrative model drawing on three prominent streams in collaboration and supply chain research. In the proposed model, supplier collaborative capabilities mediate the association between focal-firm collaborative capabilities and operational product-market outcomes (closeness of the final offering to end-user needs and delivery performance). The model is founded in the knowledge-based and dynamic capabilities views of the firm, and tested empirically with data from a sample of managers from focal firms in industries producing relatively complex final products. Evidence is found of a relationship between focal-firm collaborative capabilities and supplier capabilities, and between supplier capabilities and product-market outcomes. This study contributes to scholarship and practice in interfirm collaboration by testing an integrative model drawn from three prominent streams of collaboration and supply chain research, by clarifying the dimensions of the collaborative communications construct and investigating its relationship with operational outcomes, by investigating the mediating role of supplier capabilities on product-market outcomes, and by extendi
