If decorative images are not ignored i.e. Define what images are pure decoration and should be ignored by screen reader users. Developers need to implement the accessibility requirements and behaviors as defined by the designers and their annotated design files.įind the Buttons and Image callouts in the Assets page of the A11y Annotation Kitĥ. Designers need to annotate their designs and mockups with accessibility properties and behavior like image alt text, icon button names, and keyboard operation so developers know exactly how to code the accessible experience. Designers need to design not just the visual, mouse-based experience but also the experience for blind, screen reader users and keyboard-only users. Project managers must define the accessibility requirements for the site or app and plan for the early, middle, and late stages of accessibility reviews and testing. Therefore it’s everyone's responsibility to incorporate accessibility from the earliest stages of planning, design, coding, through to prototyping. Shift Left upends the traditional way of adding accessibility at the end of a project and instead requires the accessibility responsibilities to shift to the initial stages of software development or the left side of the SDLC. At the end of the project, it’s many times more difficult, expensive, and time-consuming to fix 100 accessibility issues, many of which require design changes rather than simple code fixes. The accessibility team or QA testing team is usually involved at the end of a project after the site or app has been launched - when the team suddenly realizes accessibility was part of the legal or vendor software requirements.īecause the site was not designed with accessibility in mind the subsequent audit report generated by the accessibility testing team is huge, possibly highlighting more than 100 WCAG failures. The traditional way of managing accessibility has been to add it at the end of the software development lifecycle after all the design and development work has been completed. The Shift Left concept moves accessibility from the end stage of the SDLC to the beginning
