Public administration undergoes constant changes in its basic forms of functioning and ongoing organisational structures. The introduced changes result from the necessity of adjusting to changes of scene and realized reforms of regime, which, next to changes in the public administration, concern the whole structure of a given state. The most important regime changes which are also connected with the structure of the public administration include changes in the territorial division of that state. The changes in this area result from social, economic and demographic changes, they are also very often dictated by a change in the legislator’s vision regarding the holistic system of managing public matters and the performance of public tasks. Nowadays, these traditional criteria are overlapped with dependencies resulting from computerisation processes that influence the application of administrative and legal regulations and the forms of the performance of public tasks.
The processes also concern the forms of contact and information flow between citizens and public entities. The management of a high level of computerisation in the area of administration processes, as observed in Estonia, allows for making the organisational structures of the state and public administration real while preserving, or even enhancing, the standards of the availability of public provisions and the performance of public tasks.
