Assessing the Effort of Repairing the Accessibility of Web Sites

Abstract

Abstract. The paper presents a new metric and a framework to assess the effort of repairing the accessibility of a Web site. For that all the HTML elements of all the pages of a site are considered, excluding those that are duplicated. The rationale is that those elements are originated in a reusable construct, such as a template and, therefore, need to be corrected only once. The evaluation then applies the accessibility evaluation techniques on those elements instead of on all the instances that are presented to the user. The reported fails and warnings are then computed in a simple sum metric.The paper also describes the validation experiment of both metric and framework, providing very important results. These may well contribute to a different perspective from managers and development team leaders about the effort to revamp the accessibility of a site.
