This paper explores obstacles to knowledge sharing motivations within organizations. The author conducted interviews with 14 employees of a research organization. Preliminary results identified two major themes: organizational structure and social interaction. At the project level, strong identification formed through shared goals and experiences motivated knowledge sharing. However, at the team level, deidentification due to unclear roles and objectives hindered motivations. Additionally, lack of feedback, work pressures, and inflexible policies presented further obstacles by failing to acknowledge or support knowledge sharing behaviors. The results indicate that organizational structures can both encourage and hinder motivations through identification and feedback, highlighting the need for organizations to understand how social contexts influence knowledge sharing.
