Based on the combination of an interorganizational perspective and a processual view of solutions, this paper analyzes the provisioning of solutions in business networks. Drawing on a case study in a transportation industry setting, the interdependencies between solutions are uncovered. The case illustrates how 1) firms are simultaneously involved in the provisioning of multiple solutions, 2) firms take on multiple roles in the provisioning of solutions in the business network, and 3) solutions are subject to interdependencies via connected relationships and thus form “networks of solutions.” The paper concludes that interdependence among solutions is a significant characteristic, adding to previous research on solutions. Consequently, it is suggested that firms' interaction with various parties in the provisioning of solutions needs considerable managerial and theoretical attention.
