Although the Republic of Croatia has recognised the importance of digitising the services of state and public administrations, so far practices have proven to be insufficiently efficient and functional. In order to improve the situation, by improving existing and developing new e-services and continuously digitising the business of public administration and increasing the share of users of e-services, SDURDD with this project aims to implement standardisation of e-services, ensure appropriate implementation of predefined e.Standards and thus contribute to increasing the use of e-services at the level of the Republic of Croatia.
