Service design is the practice of designing and improving services to better meet the needs and expectations of users. It is a multidisciplinary field that combines elements of design, engineering, and business to create services that are useful, usable, and desirable. Service design involves understanding the needs and behaviors of users, and using this knowledge to design services that are effective, efficient, and satisfying. It also involves considering the broader context in which the service will be used, including the physical, technological, and social environment. Service design is often used in the design of public services, such as healthcare, transportation, and education. It can also be applied to private sector services, such as retail and hospitality.
