Design systems are a collection of reusable components, guidelines, and best practices that ensure consistency and coherence in design across a product or organization—ultimately creating a better user experience.

• Consistency: Design systems ensure that every product, feature, or communication from a company is consistent in terms of branding, style, and functionality. Consistency helps users feel more comfortable with a product, as they know what to expect from it and how to use it.
• Efficiency: A design system can streamline the design process and save time for designers and developers by providing pre-built components, guidelines, and documentation. This allows teams to focus on higher-level design decisions and problem-solving rather than spending time on repetitive tasks.
• Collaboration: Design systems help designers and developers work more effectively as a team, facilitating communication and collaboration by providing a shared language and understanding of design elements. By establishing a shared vocabulary and process, design teams can work more efficiently and effectively together.
• Scalability: Design systems enable companies to scale their design efforts as they grow, by providing a framework that can be easily updated and expanded to accommodate new products, features, and platforms. This ensures that the design remains consistent across different products and platforms, even as the company grows and evolves.

Staying on brand is important while creating your design system and requires collaboration between all departments.
