This study investigates how global manufacturers offer advanced services through global service networks to meet customer needs. The study identifies challenges in value co-creation between manufacturers' R&D units and service network partners when providing advanced services globally. These challenges include governance, risk management, innovation, and scaling issues. The study proposes that role alignment, where manufacturers take the role of global service orchestrators and partners act as global service integrators, can help manage these challenges and establish win-win relationships. The findings contribute to understanding servitization in global markets and networks.
