Toyota Design System

Strengthening a design system used across multiple teams and products.

Toyota’s internal design system supports a wide ecosystem of enterprise products used by teams across the organization. My role focused on evolving the system through component creation, governance, and process improvements to help product teams move faster while maintaining consistency and accessibility at scale.

Toyota’s internal design system had grown difficult to manage, resulting in:

  • Inconsistencies across products

  • A growing backlog of component requests

  • Gaps between designed and developed components

  • Reduced trust and usability for product designers

Product teams needed a system they could rely on that supported both immediate design needs and long-term scalability.

The Challenge

I partnered closely with product designers through an intake process to design new components, improve existing ones, and strengthen system governance. My responsibilities included:

  • Managing incoming component requests through an intake process

  • Designing new components and enhancing existing ones, ensuring they worked both for individual teams and the broader ecosystem

  • Identifying opportunities to mature system processes and governance

  • Improving consistency between design and development

My Role

System Audit & Foundations

We began with a series of audits to understand where the system was breaking down.

I contributed to audits focused on:

  • Layout grid structure

  • Component accessibility

  • Responsiveness

These audits surfaced key gaps and inconsistencies, helping establish a clear roadmap for improving both the system’s foundations and day-to-day usability.

Component Design & Expansion

A large portion of my work involved designing and evolving components based on real product needs. Each component was designed to work for the requesting team while remaining scalable across the broader ecosystem.

To further support designers, I created the system’s first Template Library, housing reusable flows such as inline editing within data tables and VIN upload workflows. These templates helped reduce duplicated effort and encouraged consistency across products.

Template Library

This work helped re-establish trust and consistency across a growing enterprise design system now adopted by 11 products, with a roadmap to support 27 teams. By improving component quality, alignment, and governance, the system became easier for designers to rely on while supporting faster, more consistent product work.

Through this project, I deepened my experience designing systems at scale by balancing individual team needs with long-term system health and by improving design–dev alignment.
