What happens after I'm done getting buy in? Right? Something like that. And it's kind of a rhetorical question. The answer is you're not ever done getting buy in. You have to constantly again, back to the product thing. That's like saying, oh, all we have to do is pitch the product once and then people will buy it for the rest of eternity. It's like, no, no, you have to continually sell your product. You have to show it to new customers. You have to continue to keep your customers by investing in the product, by making new features, by continuing to solve problems for them. So I think the evangelism never stops. I think that's a lot of the answer is you have to constantly do that. And that's partially why the design system needs a team, needs a product owner, needs a champion to be able to evangelize the benefits of it to both the people who already use it as well as to new people.
