A service system (or customer service system, CSS) is a configuration of technology and organizational networks designed to deliver services that satisfy the needs, wants, or aspirations of customers. "Service system" is a term used in the service management, service operations, services marketing, service engineering, and service design literature. While the term frequently appears, it is rarely defined.

One definition of a service system is a value coproduction configuration of people, technology, internal and external service systems connected via value propositions, and shared information (language, laws, measures, etc.). The smallest service system is a single person and the largest service system is the world economy. The external service system of the global economy is considered to be ecosystem services. Service systems can be characterized by the value that results from interaction between service systems, whether the interactions are between people, businesses, or nations. Most service system interactions aspire to be win-win, non-coercive, and non-intrusive. However, some service systems may perform coercive service activities. For example, agents of the state may use coercion in accordance with laws of the land.

Another definition for service system^[1] states that a service system consists of elements (e.g., people, facilities, tools, and computer programs) that have a structure (i.e., an organization), a behavior (possibly described as a business process), and a purpose (or goal). A service system worldview is a system of systems that interact via value propositions.

A much simpler and more limited definition is that a service system is a work system that produces services. A work system is a system in which human participants and/or machines perform work (processes and activities) using information, technology, and other resources to produce products/services for internal or external customers. Co-production occurs in work systems in which customers are also participants, e.g., many work systems that provide medical care, education, and consulting. (Alter, 2013)
