Measure how people are using (or not using) your design system
There are two groups who need to adopt your design system: designers who use UI kits and engineers who use a code library such as React. Design adoption is easy — just swap out the UI kit and voila. However, code that is even one day old comes with technical constraints that make it hard to just flip a switch and expect all engineers to use it overnight.
To measure adoption at SurveyMonkey, we plot every product team on a five-point color scale:
