Sirio is the design system of INPS, Italy's national social security institute, the single visual and interaction language for the agency's digital services, covering standardized templates, components, and interaction rules.
It's strongest as an award-winning example (GOV Design Award, ADI Design Index, IF Design Award) of a large public-benefit institution unifying a fragmented digital experience into one coherent system, a useful case study for public-sector design at real scale.
Designers studying how a national public institution standardizes interfaces for services people genuinely depend on (pensions, benefits, social security).
Documentation is primarily in Italian, worth planning for if the goal is deep implementation reference rather than high-level visual study.
A design system for Italy's national social security institute, built for accessible public interfaces.
