The document discusses the concept of defining a product as a "whole product" rather than just the core device or service. A whole product includes all the tangible and intangible factors that create value for customers such as documentation, support, reputation, and future potential. It provides examples of how different factors contribute to customers' perception of products like computers, software, and semiconductor manufacturing equipment as whole solutions. Defining a product as a complete solution tailored for the targeted customer segment is important for competitive advantage.
