This document summarizes the key challenges in marketing services discussed in a university course. It outlines the objectives of understanding the unique nature of services and exploring their marketing challenges. It then discusses several defining characteristics of services, including intangibility, heterogeneity, inseparability of production and consumption, perishability, and lack of ownership. These characteristics can create problems for marketing services in areas of process, people, and physical environment. Specifically, services are challenging to display, protect, and justify prices for. Their production also involves customers and can be difficult to standardize or control.
