The document discusses the differences between goods and services. It defines goods as tangible things that can be touched, while services are intangible and involve acts or performances. The document outlines four key characteristics of services: 1) intangibility, as they cannot be touched, stored, or protected with patents. 2) inseparability of production and consumption, as services are performed and consumed simultaneously. 3) heterogeneity, as quality and delivery can vary. 4) perishability, as services cannot be inventoried and stored for later use. Marketing strategies for services focus on emphasizing quality training and multiple access points to address these challenges of intangibility, variability, and perishability.
