What is a key activity during the 'sustain' stage of W3C's accessibility planning?

Monitoring websites is a key activity during the 'sustain' stage of W3C's accessibility planning because it focuses on ensuring ongoing compliance with accessibility standards and maintaining the effectiveness of website accessibility over time. In this stage, regular assessments and evaluations are necessary to identify potential accessibility issues that may arise as the website evolves, such as changes in technology, content updates, or design revisions.

By consistently monitoring web content and features, organizations can ensure that they are meeting the needs of all users, including those with disabilities. This ongoing vigilance is crucial for upholding the accessibility commitments made during earlier phases of planning and implementation. The process involves collecting and analyzing user feedback, running automated and manual accessibility tests, and making necessary adjustments to address any identified issues.

Engaging stakeholders, assigning responsibilities, and building a policy framework are all vital activities that support the overall accessibility initiative, but they are typically focused on establishing the foundation and structure in the early stages of accessibility planning, rather than on the continuous improvement and maintenance phase represented by the 'sustain' stage.
