Accessibility audits ensure digital products serve all users, including those with visual, auditory, motor, or cognitive disabilities. Over one billion people worldwide live with disabilities affecting how they interact with technology. Websites and applications excluding these users miss significant audiences and violate legal requirements in many jurisdictions.
Early integration of accessibility testing in software testing prevents costly remediation after launch. Fixing accessibility issues during design costs pennies. Addressing them during development costs dollars. Remediating production accessibility problems costs hundreds of dollars per issue, plus potential legal liability. Organizations that embed accessibility from the beginning build inclusive products efficiently while reducing risk.
This guide outlines practical strategies to embed accessibility checks throughout planning, development, and QA. These approaches transform accessibility from an afterthought compliance activity into an integral quality attribute built systematically into products.
