Abstract: This paper proposes a knowledge-based strategic framework for Service Value Chain Co-Creation (SVCC) in public sector organizations. It adopts an exploratory research design that uses a descriptive research method based on the literature review of relevant studies. The proposed model is rooted in knowledge management (KM), service value chain, and Business Processes Reengineering (BPR). The integrative citizen-centric SVCC framework demonstrates how public service organizations and citizens get involved, engaged, and participate in service value co-creation. The SVCC framework proposes to capture data from citizens as input, subjects the data to various processes to create information, and offers knowledge-based customized SVCC. This research seeks to help managers focus on re-designing services and offering personalized opportunities to create greater value co-creation. The study could assist in developing the training skills required for service personnel to build effective relationships with citizens, leading to service value co-creation, satisfaction, trust, and confidence in public sector services.
