The rule

A design system must have core principles.

These principles guide all changes. They ensure consistency and quality.

A design system needs foundational principles. These principles come from user feedback. They must be read before any changes are made. Following these principles is mandatory for all team members. The principles include rules for adaptive layouts. They also define the values of the design system. A process checklist is part of the principles.

A designer wants to add a new button style. The designer must first read the design system principles. The principles state that all new components must be accessible. The designer checks if the new button meets accessibility standards. If it does not, the designer must change the button design.
