A design system is a comprehensive collection of guidelines, principles, and reusable components that ensure consistency, coherence, and efficiency in design and development processes. It serves as a centralized resource for designers, developers, and other stakeholders, providing a common language and framework for creating cohesive user experiences across products, platforms, and channels. By promoting standardization and scalability, design systems streamline workflows, foster collaboration, and enhance the usability and brand identity of digital products and services.
