At some point, someone in your organisation decided accessibility matters. Maybe a customer complained. Maybe someone got scared of the laws. Or maybe it's just someone trying to do the right thing. Either way, you've got a problem to solve.
It's a problem because the team has never had to think about accessibility before. They have no good habits to build on. You're not improving something that kinda works. You're introducing something brand new. It's a bigger organisational change.
And that's where it gets tricky.
Wanting change and making change happen are two very different things. Most organisations confuse the two. They run a workshop, share some guidelines, add accessibility to a checklist and then wonder why nothing happens.
Real change means people do things differently than they did before, consistently. Maybe not from day one, but eventually.
So before you do anything else, you need to decide what kind of change you're trying to make. Because you have two options.
You either change how people think about accessibility and hope that leads to different behaviour. Or you change what people do and trust that new habits will eventually reshape how they think.
Both can work, but you need to pick. Because you can't do both at once.
