A design isn't finished when it looks right. It's finished when it's alive, when someone has built it, it works, and someone is using it. Everything before that is a science fiction story: a nice idea about a thing that doesn't exist (yet).
That gap, between the file and the working product, is where teams are made or lost.
An engineer reads your design the way you'd read code you didn't write. So the first job is to make it legible. But the bigger shift is who you think the design belongs to. The best engineers I've worked with don't just build what's handed over. They find the edge case you missed, the cleaner path, the reason a thing won't work the way you drew it. Design at them and you lose all of that. Design with them, let them push back, and the product comes out better than anything you'd have shipped alone.
Somewhere along the way I noticed that explaining the work is also how I find out whether I understand it or not. If I can't write down plainly why a thing is the way it is, I usually don't know yet. The writing isn't the report at the end. It's the thinking.
That lesson got louder when the team spread out. I work from Buenos Aires with people across several time zones, and you learn quickly that you can't lead by being in the room, because half the time there isn't one. With no tapping someone on the shoulder, the work has to carry itself: clear enough that someone waking up twelve hours ahead can pick it up, decide, and move without waiting for me. It sounds like a constraint, good. It's the thing that forces a team to excel, same room or not.
None of this asks for one fixed process. The process should be whatever serves the solution: heavy discovery one week, getting out of the way of the right person the next.
Great handoff equals great work. The handoff was never really the point. The question is whether a team can still think clearly together when they're apart.
