Ries argues that companies lose their position by expanding their product lines and their markets, and that the correct response to competitive pressure is to narrow rather than broaden. The book extends the positioning argument he made with Trout into a specific prescription about corporate scope.
His claim is that a company's strength comes from owning a single idea or category in the customer's mind, and that every extension into an adjacent category weakens that ownership. He argues that line extension appears profitable in the short run because it uses existing brand equity and distribution, and destroys value in the long run because the brand comes to mean nothing specific. He uses examples from the 1980s and 1990s including diversified conglomerates, and contrasts them with companies that dominated a narrow category.
He distinguishes what he calls the divergence of categories over time, arguing that categories split into subcategories rather than converging, and that this creates opportunities for focused entrants while punishing companies attempting to serve everything. The practical prescription is to identify the single word or category the company owns, divest or spin off everything else, and defend the position.
The reference has not verified this title in detail beyond its central argument and its relationship to the earlier positioning work. The examples are from the period before publication in 1996 and many of the companies have since changed beyond recognition. The claim that categories only diverge has been contradicted repeatedly by convergence in technology products, most obviously the smartphone. The core prescription about scope discipline remains a useful counterweight to expansion by default.
Executives considering line extension or diversification who want a stated argument for scope discipline, with the examples treated as dated.

Positioning: The Battle for Your Mind argues that a brand competes for one specific slot in a customer's memory rather than on a list of product attributes, and that a challenger wins by occupying an empty slot instead of attacking the leader head-on. Focus makes the connected case that companies lose pricing power when they stretch a brand across categories.
