I can hardly think of something that is really a universal fit. Something that you buy off the shelf and it will fit you, your partner, your children and your parents. There's always going to be something slightly off, something that doesn't quite feel right.
You're a unique individual. There's no one quite like you. Your clothes need to be a certain size, the watch you wear made of a certain material, the car you drive with a specific set of features. In order for it to be your home, the house you live in had to be of a certain size, in a specific location, maybe with a garden at the back and garage at the front.
You likely have software installed on your computer that I don't. You're using a web browser with certain browser extensions, set up in way that suits you personally and your way of working. You might be using a mouse or a trackpad, or no pointing device at all.
And not a whole lot of people have the same setup as you. We each do our own thing.
When thinking about accessibility and remediation, there's no one size fits all solution.
Maybe you have your own way of structuring your teams and managing their work. Maybe you have squads, tribes or taskforces that come together to do the work and disband when the cycle ends. Maybe you work in one-week sprints, 6 week cycles or 3 month releases.
Maybe you do planning, create wireframes and user test them before you even touch code. Or maybe you go straight to coding a prototype and make adjustments as you go. Maybe you need sign-off from QA testers before you launch or maybe you have vague acceptance criteria.
Or maybe you do something completely different.
So if your team is unique, if your development process is tailor-made and if your business processes are one of a kind, why would you think there's an off-the-shelf accessibility solution that will fix everything for you with minimal input and effort on your part?
With accessibility, there's no silver bullet. If someone is trying to sell you one, duck!
