Case study

Lucid Motors HMI Design System

Building a reusable product language for vehicle controls, mobile surfaces, and cross-functional delivery.

Lucid design approach Lucid UX 2.0
Problem
Feature teams were creating local styles and components, which led to repeated decisions around behavior, visual consistency, and implementation details.
Role
Owned the design system from scratch as product owner, defining foundations, component priorities, documentation, review rhythms, and rollout with designers, engineers, PMs, and stakeholders.
Design decision
Converted repeated feature-level decisions into reusable HMI patterns, defining where the system should enforce consistency and where each vehicle surface needed flexibility.
Impact

Improved consistency, predictability, and accessibility across product experience, contributing to an estimated $2M annual efficiency gain by reducing repeated design and implementation effort.

Recognition

The design system work received high praise from Derek Jenkins, Lucid's Senior Vice President of Design and Brand.

01

System foundations

Styles, components, and interaction patterns became reusable product decisions.

02

HMI craft

Vehicle controls needed to feel premium, predictable, and safe in motion.

03

Cross-surface language

The system connected in-car HMI, mobile, and product tooling into one language.

04

Delivery model

Documentation and review rhythms helped designers and engineers move faster.
