Handoffs break in ways no one intended

For a long time our process looked like most design teams’: design in isolation, polish to a high shine, then hand the finished file to engineering and hope nothing got lost in translation. Something always did. Not through anyone’s fault — just the natural entropy of one team’s assumptions meeting another team’s constraints for the first time, too late to change course cheaply.

We started inviting an engineer into early, messy design reviews — sketches, not polished comps. The immediate effect was more questions and slower-feeling meetings. The longer-term effect was far fewer surprises during build, because constraints surfaced while they were still cheap to design around instead of after the visual direction had already calcified.

The real unlock was a shared vocabulary

The real unlock wasn’t a specific tool or ritual — it was building a shared vocabulary for trade-offs, so a conversation about spacing could quickly become a conversation about implementation cost without either side feeling like they were being overruled.
