57 improvement of the State unified geospatial information website, the creation of CRM functionality for the assurance of a multi-channel service provision principle or centralised provision of geospatial data. In order to ensure that for the reception of private and public sector services the same solutions may be used, it is necessary to ensure the possibility to use individual components also outside the framework of the public sector (e.g., authentication, e-signature, e-invoicing, etc.). It is necessary to continue and develop the collaboration and mutual exploitation of options of public and private sector electronic platforms and solutions, in the same time defining collaboration principles and exploitation conditions, which are directed towards long-term collaboration principles. Taking into account the tendencies of planned policy initiatives and service delivery, it is necessary to continue the development of united, secure and user-oriented service provision sites for private persons (inhabitants and entrepreneurs) that will serve as a single contact point for administrative procedures for Latvian, as well as other EU inhabitants and entrepreneurs. Also, taking into account certain transaction opening principles determined in Section 5.4.1, it is necessary to evaluate availability of central service provision platform, also publishing of (state function providing) e-services introduced in private sector. The solutions should be designed to be interoperable with EU solutions and standards. There should be centralised solutions for customer service separation from provision of services (knowledge management, event logging, and service information delivery to the responsible institution, etc.). When developing service provision sites to entrepreneurs and inhabitants: * the previous experience (Rural Support Service, the Central Statistical Office, State Revenue Service) should be taken into account; * a convergence plan should be designed for the existing customer self-service websites, the gradually moving towards exploitation of the state centralised client service solutions, do not excluding possibility that after evaluation of usefulness they may function separately, using a sharing solutions of centralised platforms. Similarly, the issues, which are not covered by national-level platforms and which are not intended for use at national level, can be developed in sector-wide ICT sharing platforms (e.g., public safety, education, health, justice, customs, taxation, digital cultural heritage, etc.). In addition to technical issues, administrative capacity of centralised sharing platform’s manager should be provided, in order to manage solutions at high quality and provide valuable methodological support to infrastructure users (standardisation of e-services development, guidelines and support, including developers). Sharing platforms and solutions developed within them must be sufficiently flexible to implement operational and incremental changes. Also, administrative procedures, which should be performed in order to use sharing infrastructure and its solutions, should be decreased or simplified. 5.4.3 Introduction of Official e-Mail Addresses for Inhabitants and Entrepreneurs information_society_development_guidelines_2014_2020.docx; Information Society Development Guidelines 2014-2020
