Product design starts before the interface
Product design is the discipline that connects behavior, operations and goals in a coherent experience.

The interface is the visible part of a system of decisions. Behind it are rules, priorities, journeys, states and different expectations that need to work together.
Product design is not aesthetic ornamentation applied at the end of the process. It is the structural discipline that explores mental models, reduces cognitive load, and connects business logic to everyday experience.
Good design means organizing this complexity and making it understandable without hiding the context needed for a confident choice.
When design leads through problem understanding, the interface ceases to be just a pretty screen and becomes a scalable operational asset.
