Technology of the service
Almost all services today make use of special machinery, and each of these machines operates on the basis of a specific technology, i.e. on a base of knowledge about the specific operation of service. An overview of the various technologies related to a given type of service usually follows the typical process of the service.
Economy of the service
The economic study of a service aims at finding an optimum between benefits and expenditures of the activity.

These are theoretical concepts (marked in red in the diagram below) which can be constructed on the basis of a few directly measurable variables (on yellow background in the diagram).
