People usually follow the easy path. The path of least resistance.
I do too. And it's not because I don’t care. Sometimes, I'm just busy, under pressure or trying to ship the best thing I can with the time I have.
But if accessibility depends on people remembering extra checks, finding separate guidance or interpreting vague standards under pressute, it will keep slipping.
Again, not because they don't care. It's just human nature. The answer is not to ask everyone to care harder.
I'd rather we make the right thing easier. Eliminate as much of the resistance we can.
That might mean giving teams clear patterns they can reuse. It might mean putting accessibility expectations (read the definition of done) where work already happens. It might mean empowering people to make those decisions faster and without waiting for outside help.
All this can only happen if we make the accessible version the obvious version. The easy version.
We need to scale quality and we can't do it through heroics. One person catching everything is ludicrous. So is having a giant policy document no one ever reads but all sign yearly.
Give people good defaults. Good defaults reduce the number of decisions they have to make under pressure.
Good defaults are usually small decisions you make now that make a big difference later.
