In Search of a Living Design System

When I started coding in the early 2000s, “design systems” weren’t even a term. We had style guides at best, often buried in a PDF or buried deeper in someone’s mind. If the font looked close enough and the margins didn’t break the layout in IE6, you shipped it.

Two decades later, I’ve built and maintained countless web apps—from monoliths in pure PHP to decoupled, modern stacks with React, Vue, Tailwind, and Laravel. Somewhere along that path, design systems grew from vague concepts to essential architecture. But here’s the problem: most of them are dead on arrival.

We build these systems to unify the look and feel of a product, to improve development speed, and to create consistency between teams. But somewhere between the Figma file and the actual implementation, it all goes sideways. Components go out of sync. Tokens drift. Documentation ages like milk. Eventually, what was supposed to be a source of truth becomes just another outdated artifact.

So what’s missing? Life.

A Living Design System Isn’t Just a Library

A lot of teams make the mistake of thinking a design system is just a shared component library. But it’s more than that. A living system needs three traits:

Connected – Your system must be wired directly into your app. That means design tokens driving actual CSS. Design decisions reflecting in real components. Versioned, modular, and consumed across teams without friction.
Observable – It needs visibility. Is a component being used? Is it out of date? Does it render correctly across themes and breakpoints? If you can’t measure it, you can’t maintain it.
Evolving – A good design system evolves. That means handling change management gracefully. When the design team updates spacing or color tokens, the dev side should respond without breaking every page in production. Think migrations, deprecation strategies, and release notes—not just blanket updates.

What This Looks Like in Practice

Here’s how I’ve approached it after years of pain:

Monorepo with shared packages: I separate the design tokens, UI components, and utility logic into packages. This lets me update and version them independently while keeping everything in one place.
Strict interface contracts: PHP taught me to value strong interfaces and clear contracts. I carry that over to front-end. A component should do one thing well and be predictable. If you’re building a button, it should always look and behave like a button—across the product.
Design-to-code pipelines: Tools like Storybook, Figma tokens, and GitHub Actions help bridge the design-dev gap. I want designers to influence code without writing it, and developers to implement without guessing.
Feedback loops: A living system requires human upkeep. That means monthly reviews, Slack channels for feedback, and a culture that respects the system, not bypasses it “just this once.”

What Kills a Design System

Over the years, I’ve seen systems fail for predictable reasons:

No governance: Without someone responsible for the system, it dies. Fast.
Lack of buy-in: If leadership doesn’t treat the system like a product, it becomes optional.
Too rigid: Paradoxically, strict systems often get ignored. Flexibility is key.
Under-communicated: If no one knows how to use it, they won’t.

What We Gain When We Get It Right

When a design system is alive, everyone wins:

Developers ship faster, with fewer bugs.
Designers trust their work will be implemented faithfully.
Users get a consistent, high-quality experience.

It becomes a virtuous cycle—where improving the system improves the product, and vice versa.

Final Thought

After 20 years of building on both the front and back end, I’ve come to see design systems not as a luxury or a “nice to have,” but as core infrastructure. Like a database schema or API contract, your design system is a foundational layer. And if you treat it like a living, evolving part of your stack—rather than a static artifact—you’ll build better software. More importantly, you’ll build it together.
