Functional Component & Module Design: The building blocks everything else rests on

Why this matters

Recurring components are the foundation of any scalable UI

Modular design significantly accelerates development of new features

Consistent components reduce cognitive load and errors for users

Accessibility can be systematically embedded at the component level

Fewer UX debates during implementation – because everything is already defined

Good components don't emerge by chance – they emerge from design principles

Tables, filter bars, form fields, status indicators: complex applications are built from recurring UI building blocks. When these are designed inconsistently or insufficiently, friction points emerge that multiply across the entire system.

We design these components in a modular and function-optimised way – with an eye on usage logic, accessibility, and scalability.

01

Component inventory

What building blocks does the system need – and which already exist?

02

Design principles per component

What are the usage logic and interaction rules?

03

States & variants

Empty, loaded, error, hover, disabled – all states defined

04

Accessibility

WCAG requirements addressed at the component level

05

Build the component library

Figma or Storybook with usage guidelines
