Links between internal and external cooperation in product development: An exploratory study

While there is an overwhelming amount of publications on cooperation in product development projects, they mainly,focus on cooperation between business functions within an organization (internal cooperation) or on cooperation between organizations (external cooperation). Yet the relationship between internal and external cooperation has received only scarce attention. This article studies how internal and external cooperation relate. Following an extensive literature study and 12 exploratory interviews with managers in eight organizations, a case-research design was set up. More specifically, six product development projects were studied in depth, combining data from interviews, questionnaires, and information from secondary sources. Based on these cases, the authors present four different links between internal and external cooperation: (1) Internal cooperation may serve as a mechanism to coordinate external cooperation; (2) Internal cooperative norms are similar to external cooperative norms; (3) External cooperation may stimulate internal cooperation; and (4) Internal cooperation may be an essential part of organizational learning from external partners. The results of this exploratory study prove the interaction between internal and external cooperation to be a subject worthy of investigation and demonstrate that in order to appreciate fully the quality of a firm's external cooperation efforts, they should be studied in combination with the firm's internal interfaces. The authors also show the managerial implications of these links, as well as some directions for further research.
