"Management is on the verge of a major breakthrough in understanding how industrial company success depends on the interactions between the flows of information, materials, money, manpower, and capital equipment. The way these five flow systems interlock to amplify one another and to cause change and fluctuation will form the basis for anticipating the effects of decisions, policies, organizational forms, and investment choices." (Forrester 1958, p. 37) Forrester introduced a theory of distribution management that recognized the integrated nature of organizational relationships. Because organizations are so intertwined, he argued that system dynamics can influence the performance of functions such as research, engineering, sales, and promotion.

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.

Absorptive capacity Collaborative process competence Collaborative engagement Buyer-supplier relationships Supply chain management Knowledge-based view, Relational view Perceived interdependence a b s t r a c tFirms are increasingly dependent on the knowledge and expertise in external organizations to innovate, problem-solve, and improve supply chain performance. This research examines two capabilities that enable firms to collaborate successfully as a means to combine knowledge and expertise in an episodic collaboration initiative. Building from two theoretical foundations, the knowledge-based and relational views of the firm, we examine the effects of absorptive capacity and collaborative process competence on the outcomes of an episodic collaboration initiative. Using structural equation modeling, we empirically validate the positive effect of absorptive capacity, collaborative process competence and level of engagement on the operational and relational success of a collaboration effort. Results show that collaborative process competence mediates the relationship between absorptive capacity and collaborative engagement, and positively influences both operational and relational outcomes. Finally, we offer suggestions for managers to improve the effectiveness of inter-firm collaboration initiatives and discuss future research opportunities.

T he connectivity and communication requirements of leading supply chains have created the emergence of a more advanced role for third-party logistics providers 3PLs. They have evolved from providing logistics capabilities to becoming orchestrators of supply chains that create and sustain a competitive advantage. This article uses a theoretical perspective based on resource-based theory, network theory and transaction cost economics, and a thorough literature review, to develop a model with seven propositions. Finally, using structured interviews of industry executives from a leading 3PL, we offer empirical support for the model and propositions that can be used to define the orchestrator role of a 3PL.
