Knowledge Management (KM) is an inevitable approach in the governance of contemporary organisations and enterprises. The advent of Information Communication Technology (ICT) has brought new opportunities and challenges in sharing, integrating, representing and disseminating knowledge. To remain at the forefront public sector also needs to have a KM Capability that will store, organise, share, utilise create and integrate their unmatched knowledge resources. A review of the knowledge management literature reveals many different definitions and perspectives on knowledge and knowledge management. Here, we provide an overview of some of this discourse along with descriptions of KM related concepts that can be used to guide KM initiatives in Public Sector. Finally a novel Public Sector KM model is tentatively suggested to act as a useful guide for further research and organisational application in public sector. This model takes a holistic approach to socially and technologically constructed KM, assuming the need for both participatory and profitable KM.
