Two decades of it. Zero-to-one builds, 100-person global orgs, and the messy middle where most of the actual work happens. These are the five I'd want to talk about.
A peer of mine leads a design team that survived a layoff round which gutted every department around it. Leadership asked each function to justify its cost. Her team walked in with revenue and retention numbers instead of completion rates or NPS, every roadmap item already tied to a dollar figure design had helped move. She kept her whole team. It's the best argument I've heard for measuring design in the business's language first, and design's second. It's the same instinct behind every outcome on this page.
