Overview

A design system is not a component library. The library is the artifact; the system is the agreement about how decisions get made, who can change what, and what happens when a team needs something the library does not have. Systems fail at the agreement, almost never at the components.

This is the most advanced course in the catalog. Over eight weeks you audit an existing product surface, define tokens, design a small set of component interfaces properly, write the documentation a busy engineer will actually read, and put a governance process in place that does not depend on you personally reviewing everything.

It assumes real experience: you should have shipped interface work and have opinions about component structure already. If you are earlier than that, Interface Design Foundations is the right starting point.

Who this is for
  • Designers and engineers responsible for a shared component library
  • Product teams whose interface has drifted across surfaces
  • Design leads formalizing patterns that already exist informally
  • Anyone who has launched a system and watched adoption stall

Interface design and front end craft

Nothing is finished until the empty state, the error state and the loading state are drawn. Those are the screens your users will actually meet.

Module plan

8 modules across 8 weeks.

Each module has one live session and one piece of practice applied to your own work.

  1. Week 1

    Auditing What You Already Have

    Inventorying every button, input and card in the product, and using the duplication you find to make the case for the work.

  2. Week 2

    Tokens and Naming

    Naming decisions by role rather than appearance, so that a theme change does not require renaming everything.

  3. Week 3

    Designing a Component Interface

    Treating each component as an API: which decisions it exposes, which it refuses, and how it fails when misused.

  4. Week 4

    Composition Over Variants

    Knowing when to add a property and when the answer is a smaller component the team can assemble themselves.

  5. Week 5

    Accessibility Built In

    Encoding focus, keyboard behavior and semantics into the component so consuming teams get it without effort.

  6. Week 6

    Documentation People Read

    Writing the page an engineer opens at four in the afternoon, with the decision guidance and the counterexample.

  7. Week 7

    Governance and Contribution

    A contribution path that does not depend on you, a deprecation process, and how to say no to a request without losing the team.

  8. Week 8

    Measuring Adoption

    Tracking real usage across the product, finding the surfaces that never migrated, and reporting the system's value honestly.

Outcomes

What you will be able to do.

By the last session of Design Systems in Practice you will have practised each of these on your own work, not on a case study.

  • Audit a product surface and quantify the cost of its inconsistency
  • Define a token layer named by role rather than by appearance
  • Design component interfaces that resist misuse and fail clearly
  • Build accessibility into components so consuming teams inherit it
  • Write documentation that answers the question at the point of use
  • Run a contribution and deprecation process that works without you

Also in Design

The craft behind interfaces people find obvious, from single screens to a shared component library.
