The past decades have been characterized by an increasing interest of companies in international trade and significant foreign direct investments, which led to a shift from localized manufacturing companies to global manufacturing networks. The main goal of this research is to analyze the management of information within the process of supplier selection in the context of manufacturing networks. The adoption of field study methodology allows understanding how the supplier selection process is carried out in Multinational Companies (MNCs) in different manufacturing sectors. In particular, this paper aims at identifying the information that mother company and their subsidiary companies share during the supplier selection process, and how they access to this information.
