The document discusses the three main types or "flavors" of white papers: product backgrounder, numbered list, and problem/solution. It provides definitions and descriptions of each type, including their audiences, approaches, typical structures, lengths, and when each type is best used. A product backgrounder focuses on the benefits of a product or service, a numbered list presents tips or points on an issue, and a problem/solution white paper introduces a new solution to a problem. The document recommends choosing a type based on the target audience and goals, and provides a quick reference table comparing the key aspects of each type.
