Start with Assessments

Elevate + Prioritize Accessibility Issues

The belief that access to information is a human right is at the very core of Tamman. The cornerstone and the starting point for many of our partner’s projects include an assessment of your digital property, application, or a specific element. This approach ensures your business can gain perspective and confidence in where you currently stand with accessibility.

Connect the Dots

An Accessibility Roadmap

Without knowing where you are, it is impossible to make a plan to move forward. Work with us to gain a better understanding of the most glaring issues of your digital property, explore where your digital priorities stand, and prioritize action items with some simple and high-level guidance. Our assessments are designed to meet your budget and timeline, while providing a remediation roadmap forward towards accessibility.

Our Approach

Throughout all assessments, Tamman follows the technical accessibility guidelines set forth by the Web Content Accessibility Guidelines (WCAG).

WCAG is developed by the Accessibility Guidelines Working Group (AG WG), which is part of the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI). 

Working from a foundation based on the information found in the WCAG, Tamman conducts a blend of automated, manual, and proprietary tests utilizing supplementary tools that are in accordance with the W3C’s guidance and recommendations.

Once the test results are compiled, we add a layer of business analysis with a hefty dose of common sense to provide you with a set of priorities for consideration.
