We initially built Anatomy across two web products: the member web app and the provider web app. Since then, Anatomy’s usage has more than doubled, across a multitude of internal tools (including provider data management, claims processing, and the web tools used by our Concierge teams) as well as Oscar for Business. Additionally, it’s developed a feedback loop with Mobile Anatomy, Oscar’s React Native design system for our mobile apps. Although there are many overlaps in the needs, each app differs wildly in its users, use-cases, and flows. Earlier in March, we got to a point where, when we did want to change a component, we were hesitant about rolling out the change to every instance of the component. To address this, we recently enabled feature flagging to gate certain features and updates in a component instead of an all-or-nothing ecosystem. This flexibility has already proven to be useful for things like A/B testing, and slow roll-outs for larger changes.
