Custom Design System

A design system is consistency at scale: reusable components, shared rules, and an interface that stays coherent as the team and product grow.

The problem you're facing

Every screen reinvents the button: inconsistencies pile up, development rebuilds what exists, and every new feature costs more than the last. Design becomes debt.

Our answer

We build your design system: audit of the existing, component library, tokens shared between design and code, and governance so it stays alive rather than becoming a forgotten PDF.

What LaMeDuSe Design takes care of

  • Audit of existing interfaces and components
  • Documented Figma component library
  • Design tokens shared (design and code)
  • Component usage documentation
  • Governance: contribution, validation, versions
  • Front-end implementation support
  • Design and dev team training

Our methodology

  1. 1

    Immersion & research

    Users, usage contexts, product constraints: design starts with understanding, not drawing.

  2. 2

    Exploration & wireframes

    Sketches, wireframes and journeys tested before any pixel: structure before skin.

  3. 3

    Design & iterations

    High-fidelity mockups, clickable prototypes and iterations with your user feedback.

  4. 4

    Handover & design system

    Source files, documented components and specs ready for development.

Tools & methods

Confidentiality

Source files are yours, licences verified for all assets, and confidentiality on your unannounced projects.

Hosting & handover

Deliverables integrate with your tools; for products we develop, the group's European hosting is available.

Design evolution

Design system evolution, new screens and iterations through product versions : with the same design team.

Why LaMeDuSe Design

We maintain our own design systems for the group's platforms: the governance we recommend is the one we practice : with the same pitfalls avoided.

Frequently asked questions

A lighter version, yes: a component library and tokens often suffice to eliminate inconsistency debt. The full system with governance is justified when several teams work on the same product.

Yes, for the value to be real: tokens and components must exist in code, otherwise the design system stays an intention. We support the front-end implementation.

Through governance: a contribution process, regular validations and versioning. A design system without governance becomes a forgotten PDF within six months.

Yes: audit of your system, component harmonisation, added documentation and missing tokens. We start from what exists rather than redoing everything.
