Abstract: The goal of this study is the development of a Knowledge Management (KM) model for self-reliant communities in Northeast Thailand. The areas and focus groups included private and government organizations in the village of Ban Nam Kliang and Ban Lao Rat Phatthana located in the District of Wapi Pathum in the Province of Mahasarakham. The developed community organization KM model consisted of community preparation, building motivations, awareness, participation, visions, making plans/developing team potentials, implementing/plans in practice, work development and summary evaluation. Every organization group generated community knowledge managers and there were KM operations comprising of building, classifying, storing, implementing, sharing and evaluating knowledge. The focus groups showed their satisfaction with work operation as a whole at a high level and success factors of KM of the community organizations included enthusiasm about learning, leadership of the researcher and participants, participatory work climate, action learning and work mechanisms or community organization KM centers. The developed KM model was found to be successful and able to create expected outcomes because the model included the conceptual framework from analyzing and synthesizing concepts and research results of qualified individuals at an international level both in the part of KM and the part of techniques of development. KM centers are drivers of groups to meet and share learning of each village and to operate work to achieve established visions, missions, goals and purposes. Each center administrative committee followed up the progress in work development through the real monthly meeting forum and the realistic forum.
