Interoperability of systems in state government bodies is necessary in order to improve and re-engineer working processes, whereas the Interoperability framework is a precondition which must be fulfilled to achieve successful communication of users in the electronic government system.
Such networked government introduces the following integration function groups:
1. incorporated communication between an individual user and system, and with persons included in the system, whereby, with all support, the user through the communication eventually has access to all service of networked government for which he/she has been authorised;
2. system interoperability, including legal, organisational, semantic, and technical level;
3. common (shared) systems and function enabled on the system level:
- social, business, operational and technical management of the system, rules, obligations, authorisations, risks, and safety,
- rationalisation, virtualisation and reduction of costs of common infrastructure and its maintenance,
- building and maintenance of integrated system of knowledge and information,
- transparency and legality,
- communication with other users and systems,
- analysis, planning, monitoring and proactive functioning of the system,
- continuous development and adjustments to new social and system needs.
In Croatia, there exists experience and functional systems in all three groups, which make a backbone of future system of the Croatian networked government. Therefore, the main task in this project will be creation of models, testing of models on pilot projects and eventually establishment of interoperability in state government bodies.
The key for inclusion of individual organisations into eGovernment system is detection of parameters for data exchange and chained processes among state government bodies. Review of these relations may be clearly shown in a table stating all interested parties on both axes, one as recipients, the other as data and service providers. In intersection fields, two organisation state common exchange parameters, which can be then after analysed and optimized on all interoperability levels of the system level.
Basically, state government bodies must state the type of delivery (document, register data, processes, and similar) their quantity in unit of time (preferably weekly, but also monthly with a mark indicating season/campaign works).
It is advisable to carry put such grasp of data immediately through piloting and implementation of standard procedures for those interested parties which participate in them and to add information to a common repository. By providing information on the implementation and results of the pilot and introduction of standard procedures, it is useful to motivate and enable others to show their interest in participation and delivery of that type of data. In that manner, the very users direct implementation in the direction which will provide fastest results (due to the participation of those parties with direct interest therefor).
Therefore, the following must be established through the establishment of interoperability function:
- office operations system interoperability (eOffice),
- authentication and authorisation system interoperability,
- registers interoperability,
- electronic services interoperability.
