Whenever I talk about applying digital accessibility principles to Business Intelligence tools, I’m often met with surprise. People frequently tell me they never considered it or ask how I came up with the idea. So, let me share the story of how it all began!
A few years ago, I had a stark reminder of how critical digital accessibility is in our increasingly data-driven world. I once worked with a stakeholder who was colour-blind, and for over six months, he silently struggled to interpret the dashboard I had designed. It was filled with low-contrast colours, and the traditional colour convention RAG (red, amber and green). Most of the report unintelligible to him.
Looking back, I wish I had known better at the time, but this experience has stayed with me. Since then, I’ve made it my mission to learn more about digital accessibility and, more importantly, how to implement it in my reporting solutions.
This reflection isn’t just about acknowledging past mistakes, but about offering an invitation to think critically about how we design reports and how we can make them more inclusive by combining thoughtful UI design with the WCAG (Web Content Accessibility Guidelines) framework.
Navigating Accessibility Challenges
When creating reports, many of us are bound by branding guidelines, existing design conventions, or even performance indicators like RAG. While these systems are familiar and often effective, they present a significant challenge to users with visual impairments like colour-blindness.
The same RAG system that is a staple for reporting on performance and progress can become a frustrating barrier for some users, preventing them from understanding important performance metrics. On top of that, tools like Power BI, which I frequently use for reporting, don’t always offer the most flexible or intuitive ways to toggle between accessible colour schemes and standard themes. So how do we balance these seemingly opposing forces, respecting brand guidelines and conventions, while ensuring that our reports remain accessible to all users? Well, ideally we should use colour combinations that by default are accessible, but that can be challenging.
Through my journey into accessibility, I realised that while UI design and accessibility might seem at odds with one another at times, they can and should be complementary. This led me to explore how we can combine elements of user interface (UI) design with the WCAG framework, especially in the context of data visualisation.
After doing some research, I found an alternative to address this issue and comply with the WCAG when designing Power BI reports. Instead of being confined to a single colour scheme or rigid brand standards, I created a feature that allows end-users to easily switch between a standard view and an accessible view.
This simple yet powerful change enables users to toggle between standard and high-contrast themes, providing a tailored experience based on individual needs.
What’s more, this feature not only meets accessibility standards, it empowers users to take control of how they view data. It bridges the gap between accessibility and traditional design, making reports more flexible, customisable, and ultimately more inclusive.
In my experience, this initiative has also raised awareness about digital accessibility among users and stakeholders. Many expressed interest and were eager to learn more about its importance, highlighting how a thoughtful design approach can open doors for greater understanding and adoption of accessibility principles across teams.
My journey into digital accessibility has taught me that small, thoughtful changes can have a profound impact on how data is consumed and understood. By prioritising accessibility in data reporting, I’ve not only empowered users but also sparked conversations that might not have happened otherwise.
I encourage you to try something similar. Experiment with integrating accessibility features into your own reports or dashboards, and see how many others start to take an interest in this important topic.
You might be surprised at the ripple effect it creates, fostering a more inclusive and thoughtful approach to design across your organization. After all, accessibility isn’t just about compliance, it’s about making sure everyone has the opportunity to engage with the data that drives our world.
