This document discusses key aspects of marketing services. It begins by defining a service as any intangible act or performance provided by one party to another. Examples of common service industries like healthcare, professional, and hospitality are provided. The 7Ps of the service mix - product, price, place, promotion, people, physical evidence, and process - are then outlined.
