A Best Practice Based E-Government E-portals Quality model. A detailed view

E-government portals are playing an important role in facilitating the citizens' life. The e-government services can be executed by citizens without any time and location constraints, which results in great benefits for them. Therefore, governments should pay a special attention to the quality of their e-government portals. In a previous work the ISO 25010 quality characteristics were mapped with the e-government portals' best practices. As a result a new e-government portals quality model based on ISO 25010 quality characteristics and the e-government portals' best practices was proposed. The aim of this paper is to present the detailed view of this quality model with its characteristics and sub characteristics. Such a quality model, will allow agencies to both; measure e-portals quality in a unified, reliable and easy manner, and identify the missing best practices that could improve the quality for those e-portals.
