The importance of design systems cannot be overstated. They provide the foundation for consistent, efficient design across products, ensuring that organisations can scale their design efforts without sacrificing quality. This article explores what a design system is, its key components, and how to build and maintain a design system. By following these guidelines, organisations can foster better cross-functional collaboration, reduce design debt, and ultimately accelerate product development.
What is a design system?
A design system is a comprehensive set of guidelines, tools, and reusable components that guide an organisation’s design and development efforts. It includes elements such as user interface (UI) kits, style guides, pattern libraries, and governance protocols. These components ensure consistency across all digital products, enabling teams to work more efficiently and produce higher-quality results.
Restive can help you understand the complexities involved in developing a design system that is adaptable, future-proof, and scalable. Our Design Systems consulting services have helped organisations build dynamic solutions that are easy to maintain and can grow as the business evolves.
The importance of a design system
Design systems are essential for organisations looking to scale their design efforts efficiently. Without a well-structured system in place, teams often face inconsistent user interfaces, higher maintenance costs, and delays in product development. A robust design system benefits an organisation by:
Scaling design
As your organisation grows, a design system allows you to maintain consistency without constantly reinventing the wheel. This not only speeds up the design process but also reduces errors and inconsistencies.
Cross-functional collaboration
A design system acts as a bridge between design, development, and product teams. By providing a common language and set of tools, it facilitates smoother collaboration across departments.
Impact on business outcomes
Design systems contribute to faster time-to-market, better user experiences, and a reduction in design debt. These factors directly influence business success by improving customer satisfaction and reducing operational costs.
Components of a design system
A design system is made up of several critical components. Each of these plays a vital role in maintaining consistency and efficiency across the organisation’s products:
UI component library
This is the first step in creating a design system. A UI component library is a comprehensive list of all the visual elements used in your product, making it easier to spot inconsistencies and areas for improvement.
Colour palettes and typography
Standardising colours and typography ensures consistency across all digital products.
Icon libraries and grid systems
A well-maintained icon library and grid system are essential for creating a cohesive visual experience. This is to assist in building and maintaining these elements, ensuring they remain aligned with your brand guidelines.
Design principles
Design principles are the rules that guide how your system should be used. These principles ensure that your design system evolves in a way that remains true to your organisation’s goals and values. It’s important to codify these principles, providing clarity and direction for your team.
Creating a design system
Creating a design system requires a structured, step-by-step approach.
UI inventory
Audit your current product interfaces to identify all UI elements in use. Look for inconsistencies, duplicated components, and patterns that need standardisation. Use this to determine what should be kept, updated, or retired.
Organisational buy-in
Build a compelling case for a design system by highlighting benefits like improved consistency, faster delivery, and easier collaboration. Use data from your UI audit, quick wins, or prototypes to demonstrate value. Secure stakeholder support, budget, and resourcing.
Team formation
Assemble a multidisciplinary team to design, build, and maintain the system. This typically includes UX/UI designers, front-end developers, and content strategists. Assign clear roles (e.g. design system lead, technical lead, governance owner), provide training, and set up rituals for collaboration and feedback.
System definition and planning
Define the purpose, scope, and principles of your design system. Decide what to include in the first release (e.g. core components, design tokens, typography, colour, spacing). Align on naming conventions, accessibility standards, and how the system will evolve over time.
Creation of foundations
Develop the foundational elements — colour palettes, typography scales, spacing systems, iconography, and motion principles. Document usage guidelines and ensure accessibility from the outset.
Component design and development
Design and build reusable components (e.g. buttons, inputs, cards) based on the defined foundations. Collaborate closely between designers and developers to ensure components are accessible, responsive, and aligned with code. Use a shared tool or platform (like Figma, Storybook, or a custom site) for consistency.
Documentation
Create clear, accessible documentation that covers component usage, design rationale, accessibility considerations, and code implementation. Ensure documentation is easy to update and share.
Governance and contribution model
Establish rules for how the system is maintained and evolved. Define contribution guidelines, versioning processes, review and approval workflows, and update cadences. Consider a lightweight governance model that balances consistency with flexibility.
Rollout and adoption
Promote the system across teams and projects. Offer onboarding support, pair with teams to implement components, and gather feedback. Create a change log and communication plan to keep users informed about updates.
Ongoing maintenance and evolution
Continuously improve the system based on feedback, product needs, and design trends. Schedule regular reviews, monitor adoption, and refine documentation. Treat the system as a living product with a dedicated roadmap.
Conclusion
Design systems are critical for organisations looking to scale their design efforts while maintaining consistency and quality. By implementing a robust design system, your organisation can improve collaboration, reduce time-to-market, and enhance the overall user experience.
