Towards More Mature Web Maintenance Practices for Accessibility

This paper proposes a need to differentiate Web maintenance from traditional software maintenance. The maintenance of a Web site is different than that of software as it is under constant maintenance and works by default in "modified environments". Building on the authors\´ previous work of automated quality measurement, a case study of large scale Web maintenance activity is described which focuses on a change to ensure that Web pages are accessible to users with disabilities. The results of the study show that organisations which have a clear and committed maintenance strategy and provide their staff with appropriate tools and training have better quality Web sites.
