Editorial
How do we make design systems work at scale? How do we organize at scale, prevent poor outcomes, and expose design systems to LLMs? And how do we establish design principles and underlying foundations to encourage stability and consistency?
In this newsletter, we look at some of the new challenges with design systems — from principles to workflows to prototyping to a lovely podcast to listen to. Happy reading!

On our end, we are up to the last stretch for SmashingConf Amsterdam 2026 🇳🇱 — our lovely new conference diving into all the fine details of design systems, accessibility, design and UX. With hands-on workshops to attend. Jump to details.
As usual, you can learn online, too: here’s a quick overview of our online workshops on UX and front-end:
- How To Measure UX & Design Impact + video courseUX (starting today!)
with Vitaly Friedman. Mar 31 – Apr 10 - Naming Design Systems Design Systems
with Samantha Gordashko. Apr 20 – May 4 - UX Leadership and Influence UX

And this week, we wish you a calm, kind, and mindful week, perhaps with fewer meetings and a bit more time to do what you truly love working on most.

1. Design Principles
Design principles are a powerful tool to align teams and inform decision-making. A wonderful resource comes from Ben Brignell: Principles.design. The growing library currently features more than 230 real-world design principles and methods, searchable and tagged, from hardware and infrastructure to language and organizations.
If you’re looking for more useful examples of design principles, including design principles in design systems, Vitaly compiled a list of further resources.

2. Launching Design System Components
How to launch design system components? Rama Krushna Behera from the Razorpay team wrote a comprehensive guide on how to add a new component to a design system. It covers the complete process from auditing and proof of concept to review, variants, organization, accessibility, and launch.
Also be sure to check out Vitaly’s writeup, in which he shares tips, templates, and resources on launching and organizing components.

3. Organizing Design Systems At Scale
Multi-brand design systems, multi-platform design systems, or design systems involving hundreds of shared components — how to organize and manage design systems at scale? Vitaly summarized valuable tips and resources to help you master the challenge of keeping things organized, while preventing secondary design systems from emerging.

4. Content Design System
Words matter. They help shape your brand’s identity, improve clarity, reduce errors, and streamline flows. And since they are so powerful, they deserve a place in your design system to keep everyone who contributes copy to your product or service on the same page. The Intuit Content Design System is a great example of what a comprehensive system for content designers, UX writers, and IA architects can look like.
If you’d like to dive deeper into embedding content design in a design system, Vitaly’s post has got you covered, with real-world examples, language guidelines, and worksheets.

5. Prototyping With AI
What are the best ways to use AI to prototype with your design system? In a recent episode of the Dive Club podcast, Lewis Healey and Kylor Hall share insights into how they scaled AI prototyping at Atlassian. They share their vision for a truly AI-native design system, ways to help AI make sense of your design system, and how the role of design system designers is changing with AI.

6. Making Design Systems LLM-Readable
LLMs can’t use a design system properly when vibe coding. They fabricate token names, guess values, and lose context between sessions, making your prototype feel off. Hardik Pandya shares a method for restructuring your design system into a format LLMs can reliably consume. It constraints the LLM at every point where it would otherwise guess, ensuring that your 10th AI session produces the same visual quality as your first.

7. The Question Podcast
Sparking deeper conversations in the design system community, that’s the goal of Ben Callahan’s collaborative learning show The Question. Each Monday, you’ll receive an email from Ben with a design-system-related question and, if you respond, an invite to a deep-dive session later that week where you’ll discuss the answers together with Ben, a co-host from the design system community, and fellow participants. A wonderful opportunity to dig deeper and learn from each other.
