"we define ‘‘service’’ as the application of resources for the benefit of another.
...
A key behavior is that service systems interact to co-create value.
...
in S-D logic, service is defined as the application of competences (knowledge and skills) for the benefit of another party. The use of the singular ‘‘service’’ as opposed to the plural ‘‘services,’’ represents a shift from thinking about value in terms of operand resources - usually tangible, static resources that require some action to make them valuable - to operant resources - usually intangible, dynamic resources that are capable of creating value. That is, whereas G-D logic sees services as (somewhat inferior to goods) units of output, S-D logic sees service as the process of doing something for and with another party. Value creation, then, moves from the firm, or ‘‘producer,’’ to a collaborative process. In S-D logic, value is always co-created.
.
The purpose of economic exchange in S-D logic is service provision for (and in conjunction with) another party to obtain reciprocal service - that is, service is exchanged for service. Whereas goods are sometimes involved in this process, they are appliances for service provision; they are conveyors of competences.
...
From S-D logic, service is the application of competence for the benefit of another. So service involves at least two entities, one applying competence and another integrating the applied competences with other resources (value-cocreation) and determining benefit. We call these interacting entities service systems. More precisely, we define a service system as a dynamic value -cocreation configuration of resources, including people, organizations, shared information (language, laws, measures, methods), and technology, all connected internally and externally to other service systems by value propositions.
...
The history of a service system is a sequence of interaction episodes with other service systems.
...
An interaction episode is a series of activities jointly undertaken by two service systems. Broadly speaking, interactions can be service interactions (interactions that aim to co-create value) or non-service interactions. For an interaction to be a service interaction, a proposal must be made by one party to another, agreement must be reached between the parties, and value must be realized by both."
