Interface Inventory
An interface inventory is an audit activity where a team collects, groups, and compares all visual and interactive elements already present in a digital product.
It is often used before creating or reorganizing a Design System.

- build a shared language
Process

What To Look For
The question is not only “are these different?”
The better question is: “does this difference communicate a real functional difference?”
If two elements do the same job, they should usually look and behave consistently. If two elements do different jobs, the difference should be clear enough for users to understand.
