Accessibility opens the door.
Usability lets people move through it independently.
Accessible vs usable: what is the difference? Does it matter?
I spend a lot of my time auditing websites and documents, but I don’t start by thinking about standards, success criteria or what will go into a report.
I start by using it. I turn on my screen reader, put my hands on the keyboard, and try to do the thing a person came there to do.
That might be finding a phone number, reading a document, completing a form or checking a piece of information that should be easy to get to.
There are times, it starts well. The headings make sense. I can move around the page easily. The form fields are labelled correctly. From a technical point of view, everything appears to be working. Then I press Submit.
Suddenly, I’m stuck. The website tells me I’ve made a mistake, but it doesn’t tell me where it is. I know there’s an error somewhere on the page, but my screen reader can’t connect that error to the field that needs fixing.
So I start searching. I move backwards and forwards through the page, listening to the same information over and over, trying to work out what went wrong. By then, the simple task has become frustrating, tiring and far less private than it should be.
I recently received a financial document that I couldn’t read using a screen reader. I had to rely on my sons to read the document and then explain it to me. Even though it is my sons and they know my financial situation, I felt like a burden to them as I had to ask them to take time out of their day to do it.
Moments like that are why I keep coming back to one simple truth: something can be accessible and still not be usable.
It's never been about ticking boxes
People often assume that because I work in digital accessibility, I must be driven by standards and compliance. They matter, of course, but they have never been the reason I care so deeply about this work.
Standards give us a starting point. They help make sure people can reach information, move through a page and interact with what is there.
But what motivates me is the moment someone can do something for themselves. They can open a document and actually use it. They can read the information they need without asking someone else to interpret it. They can complete a form without handing over their phone or their privacy. They can make a decision, book an appointment, apply for support or respond to a letter on their own terms.
Those moments are easy to overlook if you have never had to rely on someone else for them. But for the person experiencing them, they are powerful. That is why accessibility is only part of the conversation. The real goal is independence.
Accessibility is only the starting point
Over the years, I’ve realised that accessibility and usability aren’t competing ideas.
They’re partners.
Accessibility removes the barriers that stop people getting through the front door.
Usability makes sure they can actually find their way once they’re inside.
Without accessibility, many people are excluded before they even begin.
Without usability, they may get in, but they’re left to work everything out for themselves.
I’ve seen documents that pass the basic checks but still make people work far too hard to find the one piece of information they need.
I’ve used websites where every button has a label, but the process still doesn’t unfold in a way that makes sense.
I’ve filled in forms that work perfectly with a keyboard yet leave me guessing which field needs attention after an error.
None of these things always look like major failures on their own. But together, they create doubt. And doubt makes people hesitate, start again, ask for help or give up.
Good accessibility shouldn't
draw attention to itself
One thing I’ve noticed over the years is that the best accessible websites and documents rarely announce themselves. They just work. You don’t spend your time wondering where to go next, whether you missed an instruction or whether the information is hidden somewhere else. You simply get on with what you came to do.
I often compare it to walking through an automatic door. Nobody stops to admire it. Nobody talks about how well it opened. You simply walk through because that’s exactly what you expected it to do.
Accessible documents should feel the same. A person should not need specialist knowledge, extra time or another person beside them just to understand what a document is asking or telling them.
Sometimes simple really is better
Sometimes I think we’ve convinced ourselves that better digital communication means more design, more movement, more features and more ways to impress people. I understand why. Everyone wants their website or document to look polished. But polished is not the same as usable.
Some of the best digital experiences I’ve had are also the simplest. The language is clear. The headings tell me where I am. The important information comes before the extra detail. Buttons and instructions appear where I expect them. When something goes wrong, the message tells me exactly what to fix. Good usability is not about making people think harder. It is about removing the unnecessary effort that gets in the way.
This is why it matters to me
If you’ve read some of my previous articles, you’ll know I often come back to the idea of independence. There’s a reason for that. Every time someone has to ask another person to read a document, complete a form or explain a website, something is taken from them. It might be privacy. It might be confidence. It might be the simple feeling of being able to manage an ordinary task without needing permission, patience or help.
This matters for many people. As people get older, they often don’t want to feel like a burden on their family. People with disability can feel the same exhaustion from always having to ask for help, even when the help is offered with love and kindness. An accessible and usable document can change that. It gives someone the chance to read, understand and act on information for themselves, without feeling like they are asking again.
I’ve felt that. I know what it is like when technology turns a simple task into something that makes you feel dependent. I have also felt the relief when a document or website is designed well enough that I can just use it. That feeling matters. It is why I don’t see accessibility as a technical exercise. I see it as a way to give people back more control over their own lives.
Why usability needs to
be part of the conversation
This week’s episode of The Digital Access Show with David Oram reminded me that accessibility isn’t something we add after a website has been built.
It’s part of every decision we make. Choosing a theme. Writing instructions. Designing a form. Creating an error message. Organising information so it makes sense.
Those decisions all shape whether a website or document simply meets a standard or genuinely helps someone. At DASAT, that is what we care about. Yes, accessibility is the foundation for everything we do. But the job is not finished just because something passes a check.
The real measure of success is much simpler. Can someone use it confidently? Can they find what they need without being sent in circles? Can they complete the task independently? Can they walk away feeling like the technology respected their time, their privacy and their ability to make decisions for themselves?
Because that is what accessibility has always meant to me. Not just compliance. Not just checklists. Independence.
