Abstract: Many quality models have been used to measure egovernment
portals quality. However, the absence of an international
consensus for e-government portals quality models results in many
differences in terms of quality attributes and measures. The aim of
this paper is to compare and analyze the existing e-government
quality models proposed in literature (those that are based on ISO
standards and those that are not) in order to propose guidelines to
build a good and useful e-government portals quality model. Our
findings show that, there is no e-government portal quality model
based on the new international standard ISO 25010. Besides that, the
quality models are not based on a best practice model to allow
agencies to both; measure e-government portals quality and identify
missing best practices for those portals.
