10 indicators specified in the project are not always purposefully promoted (the situation has improved along with the introduction of the necessity to develop the project (incl. e-service) implementation plans). The end-uses (e-services) are also inflexible from a technical point of view and difficult to apply to constantly variable changes of the technical media and new applications. The life cycle of the projects of EU Structural Funds, the most often used waterfall development method6 and the duly unplanned funds for further development and maintenance of services, cause the situation that the initially intended adjustment of the services after the commencement of their real activity is very encumbered or practically impossible. Therefore, larger emphasis must be laid on the development of open interfaces within the planning period of 2014 - 2020 by providing the preconditions for the development of end-uses in business activity. In order to ensure sustainability of the end-uses they must be developed by observing specific principles and preconditions (an explanation on how the open interfaces and opened data affect the development of business activity is included in Subchapter 5.4 Action direction “E-Services and Digital Content for the Public”). On the other hand, it is necessary to train the public administration staff on the activity process and introduction, as well as management of the best practice processes of ICT infrastructure so that the process optimisation provides the desirable result. ● irrespective of the considerable increase of the number of electronised services during the development planning period of 2006 - 2013, there is still a low proportion of inhabitants who use e-services7, as well as little use of the opportunities offered by ICT in business activity. For example, in 2012, 9% of enterprises received orders via the Internet (the average EU indicator – 16%), while e-commerce in business activity was used by 7% of enterprises (the average EU indicator – 14%)8. The data of the survey9 conducted at the end of 2012 show that there is a low level of knowledge about electronic access to services and distrust in the Internet media. That implies that the measures aimed at the communication of e-government development with society, explanation of the e-government benefits, education of the service users, as well as explanation of the safety aspects of the electronic media use have been insufficient. Within the development planning period of 2014 – 2020 more attention should be paid to these aspects, otherwise a high risk will remain that the investments made in e-government development cannot provide a return because the e-services created as a result of these investments are not used by society. ● the state information systems and e-services in the EU Structural Funds’ planning period of 2007 – 2013 are basically established according to the needs of the particular institution with insufficient coordination of their development with other institutions who are involved in the ensuring of the relevant public administration process. Due to a lack of coordination the requirements for data exchange and integration with the information systems of other institutions were often not identified in due time and that has been the reason for delay of the projects, as well as mutual interoperability solutions of information systems and public administration processes worked out to be of insufficient quality.
