Shift Left: Moving the Inclusion of Accessibility Functionalities to the Left in Agile Product Development Life Cycle

Abstract

In modern software development, ensuring accessibility is a critical aspect of creating inclusive digital products. Traditionally, accessibility has been addressed late in the development process, often leading to costly rework and poor user experiences for individuals with disabilities. The "Shift Left" approach advocates for moving accessibility considerations earlier in the Agile product development life cycle, embedding accessibility from the initial stages of requirements gathering, design, and development. This paper explores how shifting accessibility to the left can lead to more efficient workflows, higher-quality products, and better compliance with regulations such as WCAG and ADA. By integrating accessibility testing and principles throughout the Agile process, teams can reduce development costs, enhance product usability, and foster an inclusive design culture. The paper also discusses challenges, benefits, and practical steps for adopting this approach, supported by diagrams to illustrate key concepts.
