Interface Inventory is a key research activity before any design system is started.
The goal is to collect all various pieces of UI from the product(s) that the future design system needs to support and continuously work towards more unified versions of important components like buttons, cards, fields, and many others.
This Interface Inventory Blueprint contains predefined templates for various UI elements, with additional template for synthesis of key insights. Later, these insights can be used for requirement definition from design systems components.
