I've seen teams struggle with this too; one thing that helped us was regular design system audits to identify deviations and address them before they spread.

I totally agree, I've seen teams invest so much in a design system but then not enforce it, which defeats the purpose - what do you think is the best way to ensure team buy-in?

I've seen this play out firsthand - one of our teams had a solid design system in place, but when new members joined, they didn't get the training and ended up deviating from the guidelines, causing more issues than it solved; what do you think is the best way to onboard new team members to ensure they understand and adhere to the design system?
