Case Study

Establishing Accessibility Infrastructure through Assessments

To make public transportation work in a major city, everyone from the riders to the workers need to be considered in the design process. Tamman partnered with the company that builds the back-end applications for a large public transit system. Completing thirteen thematic assessments for the applications that transit employees and riders will utilize on a daily basis.

A journey of a thousand miles begins not with one step, but with creating the map. Assessments + Prioritization establishes a roadmap toward accessibility for a transit agency.

Have you ever wished there was a tailored roadmap for accessibility specific to the needs of your business? Our client had many digital properties that were already built, but accessibility was not an established feature. Our team worked with their team to assess their needs and establish that roadmap. We evaluated and identified the critical accessibility issues within each property – web, mobile, kiosk, and more – with the client to identify the major pain points that had the highest impact on the business and the end-user. We walked through the findings together, educating their teams along the way to build a 10-year remediation roadmap. Resources can be scarce, and you don’t have to do everything at once. We’ll support the process to get you there, no matter where your starting point is.

The Challenge

Tamman evaluated and identified critical accessibility issues and worked with the client to identify the major pain points that had the highest impact on the business and the end-user. Together, we are building a 10-year remediation roadmap for this municipal client. Accessibility was not baked into any of the designs from the start. Tamman’s charge was to identify issues, prioritize them based on severity and image the solutions after properties had already been built. Working on a strict budget, the client was not able to rebuild legacy applications from the ground up. Therefore, identifying, educating, testing and re-testing or really walking the journey with our client over several months was crucial to creating lasting impact.

The Solution

  • Train Tamman’s QA Assessment team on the purpose and use of each application and digital product
  • Run thematic assessments to identify the critical accessibility gaps in the applications and products
  • Work in partnership with client’s software development team to make prioritized recommendations to remediate
  • Provide education and technical documentation along the way
  • Create a roadmap of remediation that details timeline and efforts to roll out as applications go under periodic updates and changes over time

Resources can be scarce, you don’t have to do everything at once. We’ll support the process to get you there, no matter where your starting point is.

The Result

With the accessibility report findings, we were able to identify and lay out a strong accessibility roadmap for our client. For most remediation projects, it is not uncommon to stagger remediation. In a world of scarce resources, doing everything at once is just not possible, and prioritizing different aspects of accessibility can feel really difficult. Tamman’s accessibility experts took the time to hash out not only what is needed, but in what order and why. The client now has a plan of step-by-step remediation efforts to accomplish over the next ten years and a partner in Tamman to help them whenever they need it along the way.
