Design systems provide repeatable solutions to common design problems, reducing the number of one-off decisions people need to make and creating more consistent results. These systems collect reusable components with clearly defined standards for use, combining pattern libraries, colors, and fonts with standardized design principles. By embedding these building blocks into teams and workflows, design systems ensure that consistent user experiences are achieved even when design is distributed among numerous designers and other creators. Companies like the New York City subway system's designers Noorda and Massimo Vignelli have successfully implemented design systems to achieve scalability and consistency in their designs, resulting in improved user experiences and business outcomes. Design systems help teams work smarter and faster while producing better results, reducing grunt work for designers and empowering teams to manage the design process on their own. They are also good for business, leading to cost savings, revenue gains, productivity gains, speed to market, and brand and market position improvements. Companies that adopt both structured content and a mature design system can move faster at scale without sacrificing quality or consistency, enabling them to create unique experiences while maintaining brand consistency.
