User experience design (UX) aims to enhance user satisfaction and productivity by improving the usability, accessibility, and pleasure provided in the interaction between the user and the product. UX design uses techniques from human-centered design and information architecture to understand users and specify program requirements from the early stages of product development. Service design applies similar human-centered principles to the design of services to improve customer experience. Key benefits of UX and service design include higher conversion rates, reduced costs, improved customer satisfaction and loyalty, and a competitive advantage.
