Service Design Thinking is a user-centered approach that focuses on creating and improving services by understanding the needs and experiences of users. It combines elements of design thinking with service management to ensure that services are not only functional but also enjoyable and effective for users. This methodology involves collaboration among various stakeholders, including designers, businesses, and customers. By using tools like journey mapping and prototyping, teams can visualize and test service concepts, leading to innovative solutions that enhance user satisfaction and operational efficiency.
