End-user-initiative Approach to E-government Systems Supporting Green-by-it

Applications for e-Government should be developed based on user-centered design. In the late 1990s, one-stop-service by governments became popular. In Japan, the e-Government service was promoted by priority policy programs since 2001. However, there have not been sufficient achievements. Recently some ministry in Japan issued the special report of a proposal for activation of local areas by ICT. This paper focuses on Web applications supported by the local government because citizens will obtain a lot of benefit in daily life by using them. Such applications should be developed by business professionals themselves since applications must be developed agilely and modified frequently in order for a local government to support Web applications of high usability for citizens in a timely fashion with low costs. An application for Green-by-IT based on the three-tier architecture of user interface, business logic and database is selected as a typical example and then it is developed by using application framework and visual modeling technologies.
