E-Government
Public administration has evolved significantly in recent years. In order to meet the increasing demands of the digital era, the keyword is electronic government (also known as e-government or e-administration) - the innovative concept for organising processes more efficiently and promoting proximity to citizens through digital solutions.
Efficiency and proximity to citizens thanks to the digitalisation of all business processes: Being in close contact with citizens, companies, organisations, federal, state and local authorities - this is the goal in public administration services. And with the digitalisation of business processes, this goal can also be achieved.
