Knowledge management (KM) is the process of capturing and utilizing knowledge in an organization to achieve the best performance for the organization. It is a continuous collaborative process to reach organizational objectives. KM can empower innovation and increase creativity in an organization if applied effectively. KM is utilized heavily in the private sector with significant success. The need to enhance service quality level and the emergence of the Information, Communication, and Technology (ICT) sector and globalization have forced the public sector, as well, to practice KM to cope with the competitive challenges. However, there are still gaps and challengesin implementing KM in the public and government sectors. Assessing the feasibility and effectiveness of the KM Infrastructure (KMI) elements can improve the success of an organization before implementing it. KMI is the foundation for capturing, sharing, and acquiring knowledge. The major elements of KMI include culture, structure, and technology. Thus, this study aims to assess the effectiveness and feasibility of cultural, structural, technological and infrastructure dimensions that enable KM in government organizations. The study also emphasizes knowledge capture as it is a critical starting process for the development of organizational memory and it is also considered essential to enhance an organization's innovation and performance. The study was carried out by investigating a government organization through interviews with its stakeholders and main decisionmakers. The interview was conducted for 11 participants. The result analysis was conducted using thematic analysis. The results showed that there are some cultural dimensions that are feasible and can be effectively implemented in government organizations like continuous management, support and collaboration. It was also found that not all structural dimensions are feasible and effective. There are other alternatives that can be considered like formalization and integration. Finally, some technological dimensions were labeled such as user friendly like IT-service support, security, and compatibility. The study also found that these KMI elements can be interrelated. A major research contribution of this thesis is to fulfill the research gap in knowledge management practice and infrastructure research in the public sector organizations. This thesis provides a road map for stakeholders at public organizations how to develop effective and efficient KMI and promote KM.
