A design system is a set of tools, processes, guidelines and philosophies that combine to drive how a team designs a product. The purpose of a design system is to not only systematize product development, but to also establish the processes that teams use to design, develop, test and more. As a tool, it sets the foundation for your digital experiences and products to look and feel consistent to users, increase efficiency and quality for your teams, and protect your brand across all your touchpoints in the market.
