The design-build loop
Tara Tan makes the case that the best product work happens when designing and building aren't separate phases but a single, continuous loop. The tighter that loop, the better the output. It's something most experienced practitioners know intuitively, but she articulates the mechanics well: feedback latency is the enemy of quality.
This resonates with how I think about the role of design tools that ship real code. The gap between "what I imagined" and "what got built" is where quality dies. Anything that shrinks that gap, whether it's a better handoff, a shared component library, or an AI that generates production-ready UI, is worth paying attention to.
