An explosion of ICT utilization in public life and government, in particular, appears to be one of the most clear global trends within the last decade. Nowadays, the electronic government (e-government) concept is the factor dominating the character of reforming the governments all over the world, although “numerous significant foundational issues about electronic government (e-government) remain nearly or completely unexplored” [Jaeger, pp. 702-703]. The latter is especially important for implementation of the e-government concept, it determines the variety of governmental policies regarding relevant technological, organizational, economic and regulatory issues, ensuring consistency with country's legislation and the rights of users. There are many other challenges to be dealt with while implementing e-government as far as particular stage of development is reached (see [Borins, pp.200-201], [Clark, pp. 380-382], [Jaeger and Thompson, pp.390-392]).
