Abstract

Accessibility is a particularly relevant quality attribute for web projects. Current web sites and applications do not provide satisfactory accessibility, making access difficult for users with temporary or permanent, personal or technological limitations. Accessibility is typically considered an implementation concern, thus being tackled when the application is almost fully developed, causing additional rework and an increase in costs. Our proposal is to consider this quality requirement earlier, during requirements engineering, therefore avoiding the rework caused by failures, errors and omissions in the design and programming stages. We defined a semi-automatic method to support accessibility requirements elicitation. This method is grounded on goaloriented approaches and on the WCAG 2.0 (Web Content Accessibility Guidelines), and is supported by our OmnesWeb tool. Both the method and the tool are evaluated with a case study comprising two different projects.
