You don't need to fix every accessibility problem this quarter.
Trying to do so will definitely create panic and very little meaningful change.
A better move is to look for leverage.
Where does one small decision improve many bigger parts of your product? Where does one messy pattern keep creating the same problems?
That is where accessibility starts to become useful to the business.
If every team handles forms differently, fix the way your organisation designs and builds forms. What you learn in one part of the business about forms will have a downstream effect on all parts of the business. You have more leverage than you know.
Here's one of my favourites, because there's not one team I worked with where this wasn't a problem. Error messages. If every new feature you develop creates confusion around error messages, agree what good error handling looks like. This will have a much bigger impact than you can ever imagine.
That's how you make accessibility less overwhelming. You stop treating every issue as a separate emergency and start finding the decisions underneath those issues that give you the leverage you need to reduce rework.
For a growing product team, this matters quite a lot. You probably have more work than you do time. You can't personally inspect every feature. Your team needs better defaults, clearer patterns and fewer repeated debates.
So you start small. So small you might think it's boring.
Find your leverage points, fix them and then your next feature will be that much easier.
