What step comes after 'Plan' in the W3C Web Accessibility Initiative (WAI) Steps?

The step that follows 'Plan' in the W3C Web Accessibility Initiative (WAI) Steps is 'Implement.' Following the planning phase, where the goals and strategies for enhancing accessibility are defined, the next logical step is to put those plans into action. During the implementation stage, the identified strategies and solutions are executed to improve the accessibility of web content. This often involves coding, designing, and deploying features that cater to users with disabilities, ensuring that the website or web application is accessible to all audiences.

Implementing accessibility requirements also allows for the practical application of the guidelines established during the planning phase, which is crucial for achieving the intended outcomes. This step is vital for translating theoretical accessibility goals into a tangible product that users can benefit from.

In contrast, the other options represent different phases or concepts within the accessibility process. 'Sustain' often refers to maintaining and continually improving accessibility over time, while 'Initiate' is not a recognized step within the WAI framework. 'Assess' typically refers to evaluating the effectiveness of the implementation after it has taken place, which follows the implementation phase in a continuous improvement cycle.
