At QCon London, Sophie Beaumont walks us through the tales and tools behind BBC’s WebCore design system—now handling a whopping 4.8 billion requests a month across 10 major brands.

By the end, you’ll have a handful of non-negotiable principles to keep any mega-scale design system both maintainable and downright fun.
