Accessibility projects usually begin with a clear goal: to identify barriers, remediate issues, and improve digital experiences for users with disabilities.

Teams invest time and resources into audits, remediation projects, training initiatives, and compliance. The results can be meaningful, and completing remediation can feel like a major milestone.

Accessibility is not a one-time achievement, however. It’s ongoing. And when it’s not seen as a continuous effort, it’s possible for an organization to backslide. If there’s no long-term accessibility strategy, the organization continues as it always has, and accessibility improvements gradually erode over time.

This phenomenon is often referred to as “accessibility regression”: the reintroduction of accessibility barriers into systems that were previously accessible or compliant. It’s one of the most common challenges facing enterprise accessibility programs.

Understanding why it happens and how to prevent it is essential for organizations focused on maintaining accessibility compliance and building sustainable accessibility programs.

What is accessibility regression?

Accessibility regression occurs when digital products become less accessible as they evolve.

An organization may successfully remediate accessibility issues identified during an audit, only to see new barriers emerge months later. In most cases, regression is not the result of neglect or a lack of commitment. It happens because accessibility has not yet been fully integrated into operational processes. As technology is updated, content changes, and teams evolve, accessibility barriers can be reintroduced.

Regression is the product of a reactive mindset. When accessibility exists primarily as a project — a reaction to a complaint, for example — improvements become difficult to sustain.

Understanding why accessibility efforts lose momentum is the first step toward preventing accessibility regression and building a more sustainable accessibility program.

Why accessibility efforts lose momentum

Accessibility programs rarely fail because organizations stop caring about accessibility. More often, they lose momentum because the operational structures needed to support long-term success are not fully established.

Several common factors contribute to accessibility regression:

1. Accessibility ownership is unclear

One of the most significant challenges to a long-term accessibility strategy is a lack of clearly defined ownership.

Accessibility often touches multiple teams, including design, development, content, procurement, legal, compliance, and quality assurance. When responsibilities are not clearly assigned, important accessibility requirements can fall between teams or be missed entirely.

Successful organizations establish role-based accountability while recognizing that accessibility is a shared responsibility across the business.

2. Accessibility lives outside development workflows

Many organizations address accessibility through periodic audits or remediation projects. While these efforts are valuable, they can create a cycle where accessibility is evaluated only after problems have already been introduced.

As products evolve, accessibility needs to be embedded directly into development workflows.  When accessibility reviews occur separately from design reviews, sprint planning, code reviews, testing, and release processes, the likelihood of regression increases significantly.

Accessibility becomes sustainable when it is treated as a standard quality requirement rather than a specialized initiative.

3. Design systems lack accessibility governance

Design systems help organizations scale digital experiences efficiently. However, if accessibility requirements are not incorporated into shared components, issues can be replicated across entire product portfolios. When accessibility is built into reusable components, teams can move faster while maintaining quality standards.

4. Content creation outpaces accessibility processes

Digital accessibility extends beyond applications and code. It also applies to content.

Organizations continuously publish web pages, PDFs, videos, forms, knowledge base articles, marketing content, and customer communications. Even if core platforms are accessible, newly published content can introduce barriers if there are no accessibility reviews.

As content volumes increase, organizations need scalable processes that support accessible authoring practices without creating bottlenecks.

Accessibility knowledge is concentrated in a few individuals

Many accessibility programs begin with a small group of passionate advocates or specialists. While these champions are often critical to early success, programs become vulnerable when institutional knowledge resides with only a handful of people.

Team transitions, organizational changes, or shifting priorities can quickly create gaps.  Long-term accessibility program sustainability requires broader organizational awareness, documented processes, and distributed expertise across teams.

Building a sustainable accessibility program

Preventing accessibility regression requires a shift in perspective. Rather than viewing accessibility as a project with a finish line, organizations should view accessibility as an operational capability that evolves alongside their digital ecosystem. This shift creates the foundation for long-term accessibility program sustainability.

Several strategies can help strengthen long-term sustainability:

Establish accessibility governance

Accessibility governance provides the structure needed to support consistent decision-making.

Effective governance typically includes defined accessibility policies, documented roles and responsibilities, and measurement and reporting frameworks. Governance helps ensure accessibility remains visible as priorities, teams, and technologies change.

Integrate accessibility throughout the development lifecycle

Accessibility should be incorporated into every phase of product development. Rather than being bolted on as an afterthought, it becomes part of requirements, planning, development standards, testing, and QA.

Embedding accessibility into existing workflows reduces the need for costly remediation later and helps prevent regression before it occurs.

Monitor accessibility continuously

Point-in-time audits provide valuable insights, but they only capture a snapshot of an organization’s accessibility at one moment in time.

Continuous monitoring helps organizations identify emerging issues before they become widespread problems. Combining automated testing, manual assessments, and ongoing reporting creates greater visibility into accessibility performance over time.

Monitoring also helps organizations measure progress and demonstrate the effectiveness of accessibility investments.

Strengthen procurement practices

Third-party software, platforms, and digital services can introduce accessibility risks that organizations do not directly control.

Accessibility should be considered during procurement, vendor evaluation, and contract review processes.

Establishing accessibility requirements for vendors helps prevent external systems from undermining internal accessibility efforts.

Build accessibility into organizational culture

Technology and processes are important, but sustainable accessibility programs ultimately depend on people.

Organizations that maintain accessibility successfully over time often invest in ongoing education and training to ensure that teams understand accessibility requirements and how to apply them in their daily work.

When accessibility becomes part of how teams define quality, regression becomes far less likely.

Sustaining accessibility over time

Accessibility is not static because digital experiences are constantly evolving. New content, product updates, technology changes, and organizational priorities all influence accessibility over time. Sustaining accessibility requires operational practices that evolve alongside those changes.

Organizations that focus solely on remediation may achieve short-term improvements but struggle to maintain them as systems evolve. By contrast, organizations that invest in accessibility governance, operational ownership, monitoring, and cross-functional accountability create programs that can adapt and scale over time.

The goal is not simply to fix accessibility issues. The goal is to build the processes, practices, and governance that support maintaining accessibility compliance as digital experiences continue to evolve.
