When I joined my last company ~7 years ago, the product had an informal “design system” made up of early design decisions from the founding team. As the first designer joined and the product evolved, new patterns were introduced organically, leading to growing inconsistencies and inefficiencies across the experience and design process.

While there was ongoing alignment around the need for a formal design system, higher-priority initiatives consistently took precedence. As the team and product scaled, it became clear we could no longer sustain the existing approach.

We ultimately initiated the company’s first official design system with a structured plan:

• Audited the current design and product experience

• Evaluated engineering constraints and implementation feasibility

• Conducted a full UI audit and design discovery

• Ran design system benchmarking and user feedback synthesis

• Defined core design principles

• Selected tooling and component infrastructure (e.g., Storybook)

• Built a foundational component and pattern library

• Established governance and contribution guidelines

• Defined a scalable structure for UI elements

• Drove company-wide adoption and alignment
