Nowadays services are at the center of the economic activity and New Service Development (NSD) process has gained increased attention and has been described in the literature by a sequential process that emphasizes an organizational perspective. Given this increased attention, in the last decades, a remarkable number of researchers have attempted to identify factors that are crucial for the NSD process success. However, given the complexity involved in this NSD process, it can be carried out by the collaboration of a network of partner companies. In this way, it becomes increasingly relevant to promote global service research agendas that concomitantly draw on the interdisciplinary and crossfunctional perspective of academics and business executives. This research aimed to understand the complex NSD process and how this process happens in the Collaborative Network context. This study identified desirable performance factors of NSD in the CNs context in large projects, analyzing how the factors evolve and how they influence the different stages along the NSD process. These results contribute for integrating CNs and NSD research to cope with the new challenges of large NSD project.
