How do we permanently integrate accessibility into our development processes?

The key is to anchor accessibility as a fixed part of the process, not as an afterthought. In practice, three measures contribute the largest share.

First, training for all relevant roles, so accessibility is considered already at the design stage rather than only at testing. Second, automated accessibility tests in the CI/CD pipeline that catch coarse regressions at every commit before they reach production. Third, regular manual audits, at least annually, for all those aspects no automated tool can reliably judge.

It also helps to add acceptance criteria for accessibility to the definition of done. That way it becomes routine. We support you concretely in introducing these processes, more on this under services.
