I joined the Treasury as a product designer during the COVID-19 crisis. Right when they were rolling out stimulus programs. We needed new, trustworthy, working software to support these programs asap.
I worked with developers and content strategists who launched several websites in record time. But there was a problem: each team was reinventing the wheel. Different colors, fonts, sizes, and button styles made our sites look inconsistent and unprofessional.
My creative director and I made a design system to help our teams ship high quality software faster. It has official branding, a library of accessible components, and a user guide. Over a dozen websites (and many internal applications) use it, but you can see it in action on treasury.gov or bep.gov.
