UX design: why designing screens before coding pays off
How design and prototyping save money, and why testing with users is cheaper than fixing a finished app.
The cheapest mistake is the one you catch on paper. UX design and a prototype let you walk through the key screens and flows before the first line of code — and reveal what does not make sense to users.
Changing a prototype takes minutes. Changing a finished app takes days or weeks.
Why start with a prototype
A prototype is a fast, cheap way to verify that the design solves the right problem. It lets you see the flow, name the screens and align expectations before investing seriously in development.
Testing with users
A few people and a few minutes per task is enough. Seeing where they get stuck teaches you more than hours of debate. The test does not need to be perfect — it needs to be early.
When to skip design
For small internal tools with a clear brief, minimal design is sometimes enough. But once customers use the app, design always pays off.
