This paper explores the challenges of implementing knowledge management (KM) practices within the rigid structures of public service, specifically in the field of police intelligence. Public services are characterized by stringent protocols that are essential for maintaining consistent and reliable service delivery but often hinder the adoption of innovative practices. The study highlights the crucial shift from tacit to explicit knowledge management to enhance organizational effectiveness and facilitate innovation in public sector environments, which are typically resistant to change. Through a qualitative case study approach, this research documents and analyzes existing KM practices in public security organizations, emphasizing the transformation of internal processes to improve operational effectiveness and service quality. Key initiatives include the development of an action timeline to document investigative processes, the use of post-action reviews for continuous improvement, and the establishment of a case exchange lab to foster interdepartmental knowledge sharing. The findings suggest that integrating robust KM practices can significantly enhance operational standards and collaborative efforts across units, thereby improving the overall effectiveness of public security services. The paper concludes with recommendations for further integrating KM tools that are adaptable to the dynamic and confidential nature of police work, ensuring rapid and effective responses in public safety operations.
