An adaptation of SCRUM for accessible websites development focused on testing

Both research and development of accessible websites are attempts at improving the quality of life of people with disabilities. Some of them focus on aligning with the Web Content Accessibility Guidelines (WCAG). Poor quality of content on some websites may cause rejection from users with disabilities, and the development and testing processes to ensure accessibility are often complex. This paper presents the actual experience of implementing an adaptation of SCRUM that assists in constructing and testing accessible websites continuously in the software life cycle, controlling usability and accessibility errors in a timely manner. This approach is innovative because it fosters implementation and testing of accessibility in software more quickly and with greater flexibility. Two use cases are presented, namely "Information System of Costa Rica on the Disability" (SICID, by its acronym in Spanish) and National Board of the Blind (PANACI, by its acronym in Spanish).
