Episode 071 Deep Dive: The Criticality of Design Systems with Ben Callahan & Vitaly Friedman

In Episode 071, host Ben Callahan is joined by co-host Vitaly Friedman—UX Lead, author, and founder of Smashing Conference—for a deep dive into the criticality of design systems. Vitaly brings experience from complex enterprise environments, including a multi-year engagement consolidating 199 European Parliament websites into one across 25 languages.

The survey was sent to over 1,000 design system practitioners, yielding 61 responses. Participants were asked four questions through the lens of their single most critical product: (1) what level of impact would a product failure have on end users—loss of comfort, discretionary money, essential money, or life; (2) the size of their engineering team; (3) how they ensure their design system supports that criticality; and (4) whether anyone in their org is doing workflow analysis with users.
