This study focuses on Knowledge management and knowledge sharing. The purpose is to examine potential barriers for knowledge sharing in a specific organization. The barriers will be from the perspective of actors in a specific network. Strategic knowledge sharing is based on knowledge management and organizational theory, the theoretical framework is created with this in mind. The research questions are the following: How is knowledge shared in a network organization? What barriers exist to knowledge sharing in a network organization? To investigate these research questions, a qualitative approach was taken through the use of qualitative content analysis. The study looks toward a specific network organization that in turn focuses on sharing information and inspiration to create a more sustainable future. Semi-instructed interview with different actors in the network was conducted. The result shows that without an established relationship between actors in a network, the actors themselves need to establish the connection. At the same time, a lack of communication channels creates a barrier for actors to establish contact with each other.
