Yes, I fondly recall declaring from the Funka Days stage “When we design for the extremes, everyone benefits.” And indeed when we design well, working in the framework that inclusive design is simply a subset of usability, we get a well-deserved “accessibility dividend”. That dividend includes better user experience for everyone (and better business outcomes) while lowering costs and effort: a no-tradeoffs approach to digital accessibility. Having worked with companies and governments on five continents on making their websites, their documents, their apps accessible, I can assure you that every communications professional team I've worked with that’s new to inclusive design understandably starts off fearful that it’s going to be expensive, time-consuming, and that product may lose its subtleties and appeal. And indeed that very well can happen if you don’t know how to approach it. When I share that I started off in that same place ... a bit terrified! ... I think it resonates for them: if a colourblind graphic designer can do this, surely they can too!
Like all projects, we start with strategy. My core question is always this: “How will we all know when we’ve succeeded?” Until all stakeholders have agreed to a detailed, precise answer to that question, we’re not ready to start creating an awesome solution yet.
When design goals seem to be conflicting with accessibility requirements, we pull out the measurable objectives (see above!) and typically discover there is actually no conflict at all ... or that the indicators need tweaking. If a technical conflict does indeed remain, then we go to the target audience and choose based on what usability testing tells will delight them most! In the end, it’s about the users and their lived experience.
