EXECUTIVE SUMMARYThe evolution of e-Government services is fast. There is a limited time for adaptation to the new environment in terms of legislation, society, and economy. Maintaining reliable services and a secure IT environment is even more difficult with perpetual changes like mergers and acquisitions, supply chain activity, staff turnover, and regulatory variation. Nature of the changes has become discontinuous; however, the existing approaches and IT solutions are inadequate for highly dynamic and volatile processes. The management of these challenges requires harmonized change management and knowledge management strategy. In this paper, the selected change management strategy and the corresponding knowledge management strategy and their IT support is analysed from the public administration point of view.
