60 A horizontally acceptable principle would be, for example, services, intended for public administration and entrepreneurs, already initially should be oriented only to electronic reception. It is necessary to define only digitally available public services – onsite state and local government services, which may gradually be fully digitalised, providing face to face consultations and support, if necessary. Improvable priority services should be identified that require development of cross-sectoral level service process; cross-sectoral level projects should be implemented (for example, the improvement of business environment and reduction of the administrative burden or services with high on-site demand). Information and data services that can be used in the creation of other services, including the private sector, should also be developed. For service digitalisation it is necessary to perform solution cost estimates to identify the most appropriate cost-effective form for the introduction of the service. Primary digitalised services will be determined by identifying groups of services that will provide the most significant cumulative impact on the end users (in the form of reduction of administrative burden and development stimulation) or on the improvement of public administration process efficiency. Primary digitalised services will be identified: a) by assessing the customer base, service provision intensity and the existing administrative burden. For the services with the cumulatively largest impact on society and the cumulatively largest burden, it is necessary to implement service provision and institution collaboration process improvement through ICT options; b) by determining the service groups the provision of which from the customer point of view would be organised in a single process, with the cooperation of several departments. In this case, the participating institutions will have to develop improved service provision processes, which include collaboration between institutions and multi-channel availability of the service. The detailed criteria for determining priorities of service will be developed within the framework of project evaluation criteria implemented through EU Structural funds. Justified service improvement solution will have to be provided for the improvement of services, by choosing an appropriate channel for target audience, as well as the provision of meaningful implementation of the solution and service development. Given that public services are also used by the population, with insufficient ICT skills and limited access to the Internet, a minimum access to the Internet should be guaranteed, such as through the public library network. An opportunity to receive consultations and practical assistance on the usage of public administration e-services (regardless of department) should be provided in any public or municipal service provision spot, i.a., in onsite service spots enabling usage of open access Internet for the usage of e-services. Given the broad range of the expected public e-services, they must be designed so that they can be used by the people with low ICT skills and awareness of public administration process knowledge, they must have accessible and applicable from mobile devices, as well as far as possible, people with disabilities would use them without support of others. An opportunity should be found where public solutions could collaborate with private sector solutions to, where appropriate, automate the mutual action between the state and private persons. It is necessary to carry out targeted e-services implementation and promotion measures to ensure that the resulting solutions are replaced or significantly reduce the proportion of the service request in person, including user and employee informing and education, for companies information_society_development_guidelines_2014_2020.docx; Information Society Development Guidelines 2014-2020
