What this module should change
You will be able to distinguish a design system from its assets and evaluate whether a system supports product decisions—not merely visual consistency.
Module guide
Four decisions to understand
What is a design system?
A maintained set of shared decisions, guidance, assets, and practices used to create coherent product experiences.
List the decisions your team repeats, then mark which are documented, implemented, governed, and measured.
System vs UI kit
A UI kit supplies design assets. A system also connects usage, accessibility, code, contribution, and change management.
Audit one component in a kit: can you find behavior, content, accessibility, ownership, and release information?
Anatomy of a system
Foundations, tokens, components, patterns, content, accessibility, tooling, and governance work as an operating model.
Map a product decision from principle to token, component, pattern, documentation, and release.
Maturity and scale
Maturity is the system’s ability to support safe, repeatable decisions—not the size of its component catalog.
Score adoption, coverage, contribution speed, accessibility quality, and change safety separately.
Working principles
Assets are evidence, not the whole system
A component library may show that decisions were implemented; it does not prove that teams understand when to use them or how they evolve.
Consistency is conditional
Useful systems standardize repeated decisions while preserving intentional differences between platforms, audiences, and tasks.
Adoption is a product problem
Teams adopt systems that reduce effort, explain tradeoffs, and provide a safe contribution path.
