The Digital Transformation Strategy presents the necessary processes and actions aimed at developing horizontal policies for digital transformation in the public sector of Greece, with measurable goals and measurable quarterly results. The Strategy is the answer to the fragmentation of responsibilities for eGovernment in the public sector, the often overlapping fragmented actions of different actors and organizations and the lack of comprehensive and measurable targeting for digital transformation. The Digital Economy and Society Index (DESI) of the European Union confirms the common view today: the poor digital experience of those doing transactions daily with the wider Greek public sector. The aim of the Strategy is to describe processes that will lead to more, better and more useful online services for citizens and businesses, with measurable results. Greece needs to improve its position in the DESI ranking in the European Union, and this is a national target. Modernizing the public administration is not just a matter of bureaucracy or better service; it is a question of transparency and better functioning of democracy. It is also a lever of economic development and is directly related to the field of knowledge and research. The incision to be made has the dimensions of a national target and requires the coordination of forces from both the public and the private sectors.
