This paper focuses on the importance of knowledge sharing within organizations and identifies people management practices that can effectively foster this behavior. The authors begin by analyzing the socio-psychological aspects of knowledge-sharing behavior, using theories such as the theory of reasoned action, social capital theory, social dilemma theory, and social exchange theory. These theories help identify factors that influence attitudes and intentions towards knowledge sharing. Key people management practices are then detailed, including work design, staffing, training and development, performance appraisal and compensation, organizational culture, and information technology. These practices aim to create an environment conducive to knowledge sharing, enhance social capital, and reduce perceived costs of sharing. The paper concludes by emphasizing the strategic importance of understanding and implementing these practices to ensure continuous knowledge renewal and competitive advantage in the knowledge era.This paper focuses on the importance of knowledge sharing within organizations and identifies people management practices that can effectively foster this behavior.
