Services are difficult for customers to evaluate and rely more on experience and credence qualities than search qualities. As a result, customers rely more on word-of-mouth, price, personnel, and physical cues to judge quality. They are also highly loyal to providers who satisfy them. For service providers, the key tasks are competitive differentiation, maintaining service quality, and improving productivity. Service quality is based on whether customer expectations are met or exceeded. It can be improved by ensuring reliability, responsiveness, assurance, empathy, and attention to tangibles. Productivity can be improved by training workers, standardizing processes, reducing needs through products, empowering customers, and leveraging technology.
