The complexity of design is rising. Modern design procedures demand significant cross-functional collaboration across all teams engaged in the product's development. When speed to market is so important in product development, design teams attempt to streamline the process so that products may be developed quickly without compromising user experience (Ruiz et al., 2019). It might be difficult to provide a consistent user interface across all aspects of our design. To achieve this, product teams must improve the way they develop digital products. The Design System is a set of product design guidelines, concepts, goals, and best practices. A library of user interface components, commonly designed using Atomic Design Philosophy, is a key component of the Design System. These UI components are also represented in code. For the product development team, design systems are commonly referred to as the "single source of truth." It lets the team to design, produce, and maintain a high-quality product. Any project that wishes to be easily maintained should have a Design System (“A comprehensive guide to design systems | Inside Design Blog,” n.d.). It may look challenging at first, but patience will pay off in the end. The main aim of the study is to develop a design system that will be known as "MonacoUI". It helps in increasing the efficiency of product development.
