A design isn’t finisheduntil people use it

At Theorem, an advertising agency, I was on the other side of the design file: I turned other people’s designs into real, working interactive ads on a platform called Celtra. That shaped everything I think about this job.

What I learned there is that a file is a proposal. A very good proposal, often a beautiful one, describing a product that does not exist yet and may never exist in that form.

The gap between the design and the product

Between an approved design and a shipped product there is a long stretch of decisions the file did not answer. What happens when the name is forty characters. What the empty state says on day one. What the error looks like when the connection drops halfway.

Somebody decides all of that. If the designer has moved on, it is an engineer at six in the evening making a reasonable guess. Do that a few hundred times and what ships is only loosely related to what was designed.

The product is not the file. It is what a person actually receives.

Staying close to the developers

The most valuable thing I can do on a project is be genuinely available while it is being built. Not in a review two weeks later. In the thread, that afternoon, when the question is small and cheap to answer.

Reading the code helps, but it is not really about technical skill. It is about knowing which design decisions really matter and which are just preferences to drop right away, so the team can keep moving. A designer who treats every pixel as sacred gets ignored, correctly.

Why it is worth it

So I do not consider a project delivered when the file is approved. I consider it delivered when someone who does not work on it uses it and gets what they came for.

That is slower, and it looks less impressive in a portfolio. A case study made of developer conversations and edge cases is far less striking than a grid of polished screens, which is one reason our profession keeps rewarding the file over the product. But nobody uses the file. I think the slower way is worth it.
