Design system development

Components, tokens and documentation — one source of truth for design and code, so new screens are assembled in hours.

03 04 service 3 of 4 in Web Design

What’s included

  • Components, patterns and states designed once and reused everywhere
  • Design tokens for colour, type, spacing and motion — one source of truth for design and code
  • Documentation your developers and designers will actually open
  • Figma library set up so new screens take hours instead of days
  • Handover, training and rules for adding to the system later
  • Accessibility encoded into components, so it cannot be forgotten

Who it’s for

  • Products where every screen looks slightly different from the last
  • Teams with more than one designer or more than one developer
  • Companies whose design debt now costs more than new features

In short

A design system is one source of truth for design and code: tokens of colour, type, spacing and motion, components with all their states, patterns and documentation people actually open. It is drawn once and reused everywhere, so new screens are assembled in hours instead of days and look the same across the product. Accessibility is built into the components, so it cannot be forgotten. We hand over the system with training and the rules for growing it. The price is counted in hours and fixed before the start.

What a design system gives

Design debt grows quietly: every new screen is a little different. A system stops that.

  1. 01

    Faster new screens

    Assembled from ready parts in hours, not drawn from scratch in days.

  2. 02

    One look everywhere

    Buttons, forms and tables behave the same on every screen.

  3. 03

    Fewer arguments

    Design and development speak the same language: a token or a component has one name.

  4. 04

    Changes in one place

    A new brand colour or radius changes in the token — and everywhere at once.

  5. 05

    Accessibility by default

    Contrast, focus and keyboard are built into the components, not checked by hand each time.

  6. 06

    Easier onboarding

    A new designer or developer works by the rules from the first day.

What a design system is made of

From the smallest values to the rules for the whole product.

Tokens

  • Colours with roles: background, text, accent, error
  • Typefaces, sizes and line heights
  • Spacing, radii and shadows
  • Durations and curves of motion

Components

  • Buttons, fields, selects, checkboxes
  • Tables, cards, modals, notifications
  • Every state: hover, focus, disabled, error, loading

Patterns

  • Forms, filters, search, empty states
  • Navigation and page layouts

Documentation

  • When to use each component and when not to
  • Live examples and code
  • Rules for adding new components

When you need a design system — and when it is too early

A system pays off when the same parts are used over and over by more than one person.

  • A product with dozens of screens

    Needed

    Without a system each new screen adds design debt.

  • Several designers or developers

    Needed

    Without shared rules everyone draws their own button.

  • Several products under one brand

    Needed

    The system holds them together.

  • A corporate site that will grow

    A light version

    Tokens and basic components are enough.

  • A one-off landing page

    Too early

    A system costs more than it saves.

  • A product still searching for itself

    Too early

    First find what works, then fix it in a system.

How we build a design system

Not a library “for the future”, but a system grown from real screens.

  1. Inventory

    We collect everything that exists: how many kinds of buttons, colours and spacing there really are.

  2. Tokens

    Dozens of random values become a short list of named ones.

  3. Components

    The most used ones first, with every state and accessibility built in.

  4. Design and code together

    The Figma library and the code use the same names and values.

  5. Documentation

    Short, with live examples — so it is opened, not archived.

  6. Handover and training

    The team learns to use the system and the rules for growing it.

Common design system mistakes

  1. A system only in Figma

    If the code lives its own life, the system is a pretty picture.

  2. Building for every case at once

    Components nobody uses only make the system heavier.

  3. Documentation nobody reads

    A hundred pages of theory lose to one page with examples.

  4. No owner

    Without a person responsible, the system decays within a year.

  5. Accessibility “later”

    Fixing contrast and focus in a finished system means touching every component.

Questions about design systems

How much does a design system cost?

The price is counted in hours: it depends on the number of components and products. The sum is fixed before the start; the estimate is free.

What is a design token?

A named value — a colour, a size, a spacing — that design and code use under the same name.

Can it be built on top of an existing product?

Yes: it starts with an inventory of what exists and is introduced gradually, screen by screen.

Do you work in Figma?

Yes, the library is set up in Figma, and the same tokens and components live in the code.

Who will maintain the system?

Your team, by the rules we hand over — or we, as ongoing support.
