ION is Aviva's global design system, a reusable, responsive HTML/CSS/JS component library used across the insurer's websites and partner-branded products worldwide.
It's strongest in its release discipline: updates ship roughly monthly, with the component library and documentation handled by developers and the master Figma file kept in sync by designers on the same cadence, so design and code rarely drift apart.
Design system managers studying how a large enterprise coordinates a monthly release cycle between design (Figma) and engineering (component code) without one side falling behind.
It supports theming for partner-branded products specifically, a useful reference for anyone building a design system that has to serve white-label variants, not merely one brand.
