What Is a Design System?

A design system is a comprehensive collection of reusable components, patterns, and guidelines that ensure the visual and functional consistency of your product. It’s more than just a style guide—it’s a single source of truth for how products are built across a range of digital platforms, allowing for seamless collaboration between designers and developers.

At its core, a design system includes:

• UI components: These are the foundational elements such as buttons, forms, icons, etc., that are consistently used across user interfaces.
• Design guidelines: These provide a set of rules for how the visual elements of a product (like typography, colors, and spacing) should be applied.
• Code snippets: Ready-to-use code that allows developers to quickly implement components with minimal adjustments.
• Pattern libraries: Solutions for common design problems that provide a reference for designers and developers.

How to Create the Best Design System: Step-by-Step Guide

1. Define Your Brand’s Core Values and Goals

Before you start building a design system, it’s important to understand your brand’s identity and the goals of your product. This includes identifying the company’s core values that the system needs to reflect and aligning your design language with those values. Your design guidelines should directly tie into this foundation.

For instance, is your product focused on accessibility? Do you want your brand to have a minimalistic, clean aesthetic, or a bold, engaging one? Having a strong sense of direction from the start ensures that your design system aligns with the company's core values and resonates with your end users.

2. Draw Inspiration from Popular Design Systems

One of the best ways to kickstart your process is to explore well-established design system examples such as the Atlassian Design System, Google Material Design System, and Apple’s platform guidelines. These systems showcase how major companies manage consistency across their digital products and provide useful insights for your own process.

For instance, the Google Material Design System emphasizes smooth animations, clean interfaces, and simple components that adapt well across different platforms. By studying these design systems, you’ll gain valuable ideas on structuring your own.

3. Identify the Key Components and Patterns

Every design system needs a well-defined set of UI components and design patterns that serve as the building blocks for user interfaces. These components should be designed to be flexible yet consistent, adaptable to different platforms, and easy for designers and developers to use.

Common components might include:

• Buttons and form elements
• Navigation bars
• Grids and layouts
• Alerts and modals
• Icon sets

You also need to document the design patterns that guide how components should be assembled. For example, defining how error states are presented across forms, or how modals should behave when triggered, provides a consistent user experience.

4. Build a Component Library

A central component library acts as a repository where all of your UI components are stored. It serves as the backbone of your design system, giving teams a one-stop shop for all the components they need.

A well-organized component library ensures that designers and developers can quickly find and implement consistent components without having to rebuild them from scratch. Moreover, it supports easy customization, allowing for slight variations when needed for specific sub brands or projects, while still adhering to the core design system.

By centralizing these components, you reduce inconsistencies, enhance efficiency, and streamline communication between teams.

5. Ensure Clear and Detailed Documentation

For any design system to work effectively, it requires detailed documentation that outlines how and why each component and pattern is used. This documentation serves as a resource for both designers and developers, ensuring everyone is on the same page.

What Should Be Included in Design System Documentation?

• Component usage: When and where to use each component.
• Design guidelines: Explaining the logic behind color choices, typography, and spacing.
• Code snippets: Predefined code that developers can copy and implement.
• Detailed usage guidelines: Offering more in-depth explanations of complex components or patterns.

6. Foster Collaboration Between Designers and Developers

The most effective design systems are created through ongoing collaboration between designers and developers. It's crucial for both sides to communicate clearly and ensure that the designs are both beautiful and functional. The design system team should include members from both design and development, enabling constant feedback and iteration.

Moreover, fostering collaboration helps teams align on the design process, ensuring that the UI components are flexible for future iterations and expansions. Both teams should engage in continuous discussions, reviewing the design system's progress and proposing improvements based on real-world feedback.

How to Maintain and Evolve Your Design System

Once you’ve built a design system, it’s not a static product. As your organization grows, the design system must evolve to meet new challenges and opportunities.

1. Regularly Update and Iterate the System

Design trends evolve, and so do user expectations. To keep your design system relevant, make sure it’s regularly updated to reflect modern aesthetics, usability principles, and the latest version of the brand’s goals.

2. Adapt Across Different Platforms

The beauty of a strong design system is its ability to work seamlessly across multiple platforms. Whether your product appears on mobile devices, web apps, or even digital products like smartwatches, your design language must be consistent but adaptable. Ensure that your design guidelines are flexible enough to account for different platforms and use cases.

Common Challenges in Creating a Design System

Building an effective design system comes with its own set of challenges, including:

• Promoting consistency: Ensuring that consistent components are used across multiple platforms can be difficult as your team and product line grows.
• Managing multiple teams: When you have many development teams and designers, maintaining alignment on the design system can be tricky. It’s important to set up a framework for governance and communication to address this.
• Keeping documentation up to date: As new features are added or old ones evolve, keeping your detailed documentation updated becomes a significant task.

Common Problems in the Best Design Systems

Even the most well-constructed design systems face challenges as they scale and adapt to new needs. Despite the many benefits they offer, such as consistency and efficiency in product development, issues can arise within the design system itself, especially when trying to meet the demands of multiple teams and platforms. Below, we discuss some of the most common problems seen in leading design systems like the Atlassian Design System, focusing on the pain points that both designers and developers often encounter.

1. Overwhelming Complexity

One of the major problems in large design systems is the sheer complexity they can accumulate over time. As more UI components are added, and the number of design tools and templates grows, the system can become difficult to navigate and maintain. Designers may struggle to keep track of all the design patterns, pattern libraries, and key features included, especially when the design system team continues to expand the scope to meet new requirements.

For example, the Atlassian Design System is comprehensive, but with so many design elements and design templates, designers and developers may find it hard to locate or use the right UI components. This complexity can slow down both product designers and developers, defeating the original purpose of improving efficiency.

2. Lack of Flexibility in Design Patterns

Another issue is that predefined design patterns and style guides can sometimes become too rigid. Design systems are created to promote consistency, but they can also limit creativity by locking designers into specific common patterns. This often leaves less room for experimentation or innovation, particularly when trying to design for unique or niche use cases.

In some cases, product designers need more flexibility to adapt consistent designs to a particular product’s or platform’s needs. However, adhering too strictly to the design language of a design system can prevent them from creating user interfaces that feel fresh or unique to the apple platform or other evolving platforms.

3. Difficulty Keeping Documentation Up to Date

For a design system to function properly, style guides, pattern libraries, and detailed documentation must be continually updated. This is a persistent problem for design system teams, as they struggle to maintain accurate records of UI components, design tools, and other elements.

As new components are added or existing ones are updated, the documentation can quickly become outdated. Teams who rely on this documentation to answer the same questions repeatedly about how to use certain UI kits or design elements may run into issues when the guidance is unclear or missing. Without up-to-date documentation, developers and designers might implement designs incorrectly, leading to inconsistency across the product.

4. Insufficient Collaboration Across Teams

Another common challenge is ensuring seamless collaboration between designers and developers who are working on different products or platforms. In many cases, design systems are built with a single platform or product in mind, which may not scale well across multiple platforms or sub-brands.

When the design system team does not foster sufficient communication across the company’s various development teams, issues like duplicating efforts or diverging from common solutions can occur. This fragmentation is particularly problematic when trying to apply the same design language to building websites, mobile apps, or other digital experiences. Without a consistent framework, the final product may deviate from the original design.

5. Accessibility and Onboarding Challenges

For a design system to be successful, teams need to be able to easily access and understand the design elements and components it contains. However, onboarding new designers or developers into a large and complex design system can be challenging. The learning curve can be steep, especially if the system lacks a clear structure or style guide for new users.

This is a common issue in large systems, where newcomers are often overwhelmed by the number of UI components, design templates, and tools available. If they are not provided with adequate training or onboarding materials, they may struggle to use the system effectively.

6. Inconsistent Application Across Platforms

One of the core goals of a design system is to promote consistent designs across multiple platforms and products. However, ensuring that every user interface adheres to the design language and patterns set forth by the system can be challenging, especially as design teams grow and expand to different regions or products.

For instance, applying the same design patterns from a design system built for websites to mobile apps or the Apple platform may require significant adjustments. Designers often need to account for platform-specific nuances that may not be fully addressed in the design system itself, leading to potential inconsistencies.

7. Lack of Scalability for Growing Teams

As companies expand, their design systems must also scale to accommodate more designers, developers, and products. However, not all design systems are built with scalability in mind. Smaller design systems can quickly become outdated or inadequate as the number of team members and projects grows, leading to confusion and inefficiency.

Moreover, it can be difficult for a design system community to maintain an ever-growing collection of UI components and design tools that must meet the needs of various teams. The problem arises when a design system lacks the capacity to evolve in response to feedback from a diverse set of users, products, and product designers.

8. Misalignment with Business Objectives

Lastly, a significant issue can arise when a design system is not aligned with the business objectives or fails to reflect the evolving goals of the company. While the design system might have been initially created to solve specific design challenges, it can become a burden when the company pivots or introduces new product lines.

If the design system does not adapt to accommodate new objectives or the needs of different departments, such as marketing or product management, designers and developers may struggle to stay aligned with business goals. This misalignment can lead to the design system becoming an obstacle rather than a tool for innovation.

Conclusion: How to Build the Best Design System

To create the best design system, you must focus on building a comprehensive, well-documented, and adaptable structure that brings together designers and developers. Whether you’re drawing inspiration from leading design system examples like Atlassian or Google’s Material Design, or creating your own design system from scratch, the key is to build a flexible, scalable system that promotes consistency, fosters collaboration, and allows for easy adaptation to changing trends.

By combining the right mix of UI components, guidelines, and collaborative tools, your design system will become the foundation for creating user-friendly, efficient, and accessible digital experiences across your organization’s products.
