Maintaining Systems Over Time: Living Product vs Static Spec

Design systems and style guides require fundamentally different maintenance mindsets:

• A Style Guide is largely static: Once brand rules are established, guidelines change infrequently until a major corporate rebranding occurs.
• A Design System is a living product: It requires dedicated product ownership, a groomed backlog, regular release cadences, automated regression tests, and SemVer versioning (e.g., breaking changes in major releases, new components in minors, bugfixes in patches).

Regular interface audits, automated deprecation notices, and community contribution models keep the design system healthy and prevent it from becoming an obsolete bottleneck.
