Résumé
Faced with increasingly complex and globalized Supply Chains (SC), organizations rely on industry 4.0 technologies to support these challenges. Inter-organizational information systems (IOIS), which enable SC integration with information sharing and better collaboration between the various partners, are evolving according to these new technologies in order to improve SC performance. Thus, alongside Electronic Data Interchange (EDI), which concerns a majority of existing research, more collaborative IOIS, better adapted to networked SC, have been introduced. Often available with a cloud computing technology, they can be developed as an industry standard. In this thesis, we focus on the procurement process in the SC and chose to study supplier portals. The adoption of these portals in a SC has often encountered difficulties or even failed, sometimes turning an ambitious industry standard project into a poorly used tool. Indeed, the adoption and implementation of such portals raises issues about system interoperability, process coordination and collaboration among the various partners. Thus, addressing these issues through a multi-level analysis, we raise our research question: how does the implementation of a supplier portal in a SC affect the SC integration and collaboration capabilities? Our methodological approach is based on two longitudinal case studies taking into account the duration of the project. The first case, exploratory in nature, identifies two types of facilitating mechanisms – technological and relational – which, when combined, create an integration-collaboration dynamic between a customer and its suppliers during the implementation of a specific portal. The second case, explanatory in nature, is related to the supplier portal of the European aerospace industry. It presents three levels of analysis (organisational, interorganisational, industry) combining 14 mechanisms which can explain the adoption of an industry portal. Thus, our research makes it possible to characterize the ecosystem favorable to the adoption and success of a supplier portal project, enhancing the SC integration and collaboration capabilities.
