This document discusses how to define, classify, and manage services. It begins by defining a service as any intangible act or performance offered from one party to another that does not result in ownership. Services are then classified based on whether they are a minor or major component of a product offering. The document outlines key ways services differ from goods, such as that services cannot be produced, stored, or transported in the same way as goods. It also notes that services have more variability than goods. Finally, the document provides strategies for improving quality control of services and better matching service supply and demand.
