Service system-3

Definition
"Service system" is a term very frequently used in the service management, service operations, services marketing, service engineering, and service design literature. While the term frequently appears, it is rarely defined. Given the growing importance of this term in the literature, this entry begins to organize historical usages, examples, and inferred definitions. A service system worldview is a system of systems that interact via value propositions.

One recent 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 global economy. The external service system of the global economy is considered to be nature's services or 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.
