Brand guidelines and design systems solve related problems. Guidelines explain how an identity should be expressed. A design system helps a team apply shared decisions through reusable interface patterns, components and documentation.

You do not need an extensive component library for every branding project. The useful question is where people repeatedly make the same design decisions, and what would help them make those decisions consistently.

When do brand guidelines need to become interface rules?

Start with the applications your team maintains. A small business producing occasional documents may need a good template library. A product team shipping screens every week may also need agreed interaction states, coded components and a process for managing changes.

Signs of a gap include several versions of the same button, inconsistent form behaviour or repeated debate over spacing. These are specific problems a system can address. A new library will not, by itself, resolve unclear ownership or a product strategy that changes every week.

Begin with a small set of shared decisions

Document the foundations people actually use: type hierarchy, spacing, colour roles, borders and emphasis. Separate a colour’s raw value from its purpose. For example, a token named “action-primary” communicates more intent than a list of unexplained blue swatches.

The Design Tokens Community Group format specification provides a reference for representing design tokens. Adopting a token format does not automatically synchronise Figma and code: that requires a deliberate toolchain, mapping and review process.

Prioritise components around real workflows

  • Navigation: current-page states, keyboard focus and behaviour at smaller widths.
  • Buttons and links: clear action labels, hierarchy and disabled or loading states where needed.
  • Forms: labels, instructions, validation and useful error messages.
  • Tables and cards: content hierarchy, overflow and behaviour with long or missing content.
  • Feedback: confirmation, progress, empty states and recovery from failure.

Build the patterns that repeat in the product rather than every component imaginable. Test them with realistic content, including names, numbers and labels that do not fit the neat demonstration.

Example: reading Targe as a system of decisions

The Targe studio project brings tasks, project details and workspace information into a shared interface. It is useful to inspect how navigation, status indicators, cards and data presentation relate across screens.

Use the visible work to discuss consistency and hierarchy. It does not establish a measured reduction in development time or prove that a component library will suit another organisation. A new project still needs its own workflow review and implementation scope.

What should a handover include?

Agree which design files, source files and implementation examples will be supplied. Document component states, responsive behaviour, content rules and accessibility considerations. Link guidance to examples so the next person can see both the rule and its use.

For forms, the W3C form-labelling tutorial explains how labels identify controls and connect to them. Include this behaviour in implementation checks, not just a visual label in the mockup.

Decide who maintains the system

Assign an owner, agree how new components are proposed and define how changes reach existing pages. Record exceptions rather than letting them quietly become a second system. A shared library needs maintenance just as the product does.

For a smaller team, a focused set of foundations and commonly used components may be sufficient. Expand when repeated needs justify it. This keeps the system useful without turning documentation into a separate product nobody can maintain.
