Enterprise architecture has been used in a number of ways in public administration in the Czech Republic. The most widespread use of enterprise architecture has been in controlling for ICT projects, based on Resolution of the Government of the Czech Republic No 889/2016, and for projects financed from the European structural funds. At the same time, we have seen the development of the “National Architectural Plan”, which is a set of architectural models of central elements of eGovernment on the national level, which is gradually being extended to include models for individual central state administration bodies and territorial governments. Enterprise architecture is used (and will continue to be used) not only to design better ICT projects but also as the foundation and starting point for other management methods in public administration, in particular the management of service catalogues, process optimization, quality management and productivity management in public administration.
