『The 22 Immutable Laws of Marketing』要約

The 22 Immutable Laws of Marketing, written by Al Ries and Jack Trout, presents a set of fixed principles the authors argue govern success and failure in the marketplace. Published in 1993, the book draws on examples from companies such as Coca-Cola, IBM, Burger King, and Xerox to illustrate its rules, which are framed as laws that cannot be violated without consequence. Each chapter is built around one law with a short explanatory title. Among the best known are the Law of Leadership, which holds that it is better to be first than to be better; the Law of the Category, which argues that if you cannot be first in a category, you should create a new one you can lead; and the Law of the Mind, which states that it is better to be first in the mind than first in the marketplace. Other laws include the Law of Perception, the Law of Focus, the Law of Exclusivity, the Law of the Ladder, and the Law of Hype. The book’s central argument is that marketing is a battle of perceptions rather than products, and that consumers organize brands into mental ladders within each category. Ries and Trout contend that companies often fail by ignoring these laws, for instance by extending a strong brand into unrelated areas, a violation of the Law of Line Extension. The authors use historical case studies and contrast successful and unsuccessful campaigns to support their claims. The result is a compact, prescriptive volume that became a widely cited text in marketing and brand strategy, and it remains associated with the positioning approach the authors helped popularize.
