  78. ISO 24516-1:2016 - result of a process [adapted from ISO 9000:2005]. Service is the result of at least one activity necessarily performed at the interface between the provider of the service and, in the first place, its user and, in the second place, a stakeholder. The word “service” in common English can also refer to the entity providing the actions related to the subject in question, as is implicit in such phrases as “bus service”, “police service”, “fire service” and “water or wastewater service”. In this context and usage, “service” implies the entity that is delivering the service, e.g. “the public transport of passengers”, “the provision of public security”, “fire protection and response”, and “delivering drinking water or collecting wastewater”. If “service” can be understood in this way, “water service” becomes synonymous with “water utility”; hence in this document, in order to avoid confusion, only the definition in 3.19 applies.

Voldoende in de war gebracht door 'standaarden'? Lees dan het USM-boek en  de blog "100+ horrifying definitions" en leer wat de kortste en meest pragmatische definitie van een service is die je ooit tegen zult komen.

"In der Einfach zeigt sich der Meister"

De meest universele definitie van een service is die van USM: "een service is een ondersteunde voorziening". Toepasbaar op elk vakgebied en op elke service.
Een voorziening is gedefinieerd als een combinatie van goederen en handelingen. De ondersteuning wordt gedefinieerd in het USM Klant-Leverancier Interactie Model. Deze unieke definitie is één van de bouwstenen van de USM servicemanagementarchitectuur.

PS - als je denkt dat je alles wel gezien hebt, dan kun je altijd nog hier tegenaan lopen:

“Service is the act of integrating and applying competences and other resources by two or more parties within dynamic service ecosystems, with the intent to co-create value, with a focus on relationship-building, and with consideration of the context-dependent, unique and phenomenological nature of value from service.” [Quote from Reflections on XLA].
