can be summarized as ‘what the service does’ and can be used to determine whether a service is ‘fit for purpose’. To have utility, a service must either support the performance of the consumer or remove constraints from the consumer. Many services do both.

is ‘fit for use’. Warranty often relates to service levels aligned with the needs of service
