Design school teaches a habit that most engineers never pick up: before you touch the final medium, you thumbnail it. Ten rough sketches, thirty seconds each, before anyone commits to a single line. The point isn’t the drawing — it’s that bad ideas die cheap on paper and expensive in production.
Most of us skip straight to the keyboard. A new service, a schema change, an integration — and the IDE is open before the shape of the problem is even settled. The cost shows up later: a data model that fights every feature built on top of it, a service boundary that turns every small change into a three-team coordination exercise.
Try this instead. Before writing code for anything non-trivial, spend ten minutes with a pen and paper — or a whiteboard app, if paper feels performative — and sketch three different shapes the solution could take. Not detailed diagrams, just boxes and arrows showing where data lives, what talks to what, and where the seams are. Nine times out of ten, the first shape you’d have coded isn’t the one you’d choose once you can see two alternatives next to it.
This costs almost nothing and catches the mistakes that are cheapest to fix before they exist as code. The keyboard is where you build the thing you’ve already decided on — not where you should be deciding.
