Method book; OL record is a later edition.
Hagstrom, a portfolio manager, was the first to systematise Buffett's approach into a set of stated criteria, and the book was a bestseller in 1994 and has been revised twice. It reconstructs the method from Berkshire's public disclosures, the shareholder letters and Buffett's public statements rather than from access.
The framework organises the criteria into four categories. Business tenets require a business that is simple and understandable, has a consistent operating history and favourable long-term prospects. Management tenets require rationality in capital allocation, candour with shareholders, and resistance to what Buffett calls the institutional imperative, meaning the tendency to imitate peers. Financial tenets require focus on return on equity rather than earnings per share, calculation of owner earnings, high profit margins and the requirement that each dollar retained create at least a dollar of market value. Market tenets require determining the value of the business and buying at a significant discount.
Hagstrom also traces the intellectual lineage from Graham, Fisher and Munger, and covers the case studies including Washington Post, GEICO, Coca-Cola, Capital Cities and General Dynamics with the numbers Buffett would have seen.
The book is derivative by construction, since everything in it comes from public sources and Buffett states the same principles more precisely himself. The later editions add material on Buffett's approach to focus investing and to probability. The reconstruction of the case studies with contemporaneous figures is the part that adds something the original letters do not, since it shows the arithmetic at the time of purchase.
Investors who want Buffett's criteria organised into a checklist with contemporaneous case arithmetic, understanding that everything derives from public sources.

The Warren Buffett Way was the first book to reconstruct Buffett's purchases as a repeatable set of business, management, financial and valuation tests, and it set the template later Buffett books follow. Latticework and Investing: The Last Liberal Art carry the same argument into physics, biology and psychology as sources of investment models.
