Contributing to a design system
We heavily contributed to the ONS design system adding newly designed components, patterns and accessibility enhancements. These contributions made for a reliable, flexible framework powering many Office for National Statistics services, including Census 2021.
A lot of components and patterns started based on user requirements from Census 2021. They would then be added into the design system, tested and made available for other services that may benefit from tried and tested patterns. It would take a few people to agree on the quality of coding and usefulness of patterns before being approved and merged.
In some cases, a pattern would be tagged as experimental to allow user testing to confirm its usefulness before being introduced for use across services.
