My Years with General Motors
Insider account: Sloan's own record of decentralized management.
Summary
Sloan ran General Motors from 1923 to 1946 as president and chief executive and until 1956 as chairman, and this book documents the management system he built. It was written with substantial staff assistance and delayed by GM's legal department for years over antitrust concerns.
The central structural contribution is decentralised operations with coordinated control. Sloan divided GM into divisions with operating autonomy and profit responsibility, while centralising financial control, capital allocation and policy at the corporate level through committees. He describes this as a permanent tension rather than a solved problem, and he is explicit that the balance requires continuous adjustment.
The product strategy was a car for every purse and purpose, a ladder of brands from Chevrolet through Pontiac, Oldsmobile, Buick and Cadillac, each at a defined price point, which allowed GM to compete against Ford's single-model strategy across the whole market and to move customers up the ladder as their incomes rose. Sloan also introduced the annual model change and instalment financing through GMAC, both of which changed the industry.
The financial control material covers return on investment as the governing measure, standard volume accounting that allowed division performance to be assessed independently of the business cycle, and the forecasting and inventory control systems developed after the 1920 and 1921 inventory disaster. The book is dry and written in an institutional voice. Sloan says nothing meaningful about labour relations, which were violent during his tenure, and nothing about the products themselves. Drucker's Concept of the Corporation covers the same organisation more analytically. It is a primary source on the invention of the multidivisional corporation.
Key takeaways 8
- Divisions should hold operating autonomy and profit responsibility while capital allocation and policy remain centralised, which is the multidivisional structure Sloan built.
- The tension between decentralisation and coordination is permanent and requires continuous adjustment rather than a settled answer.
- Return on investment should be the governing measure for divisions, because it prevents growth funded by capital that earns poor returns.
- A ladder of brands at defined price points allowed GM to compete across the whole market and to retain customers as their incomes rose.
- Standard volume accounting allowed division performance to be assessed independently of where the business cycle stood.
- The 1920 inventory collapse forced the creation of forecasting and inventory control systems that became a permanent competitive advantage.
- Financing purchases through a captive credit subsidiary expanded the market beyond what cash buyers could support.
- Committees composed of both operating and staff executives were the mechanism for coordination without removing divisional authority.
Who should read it
Executives designing multidivisional structures and capital allocation processes, wanting the primary source rather than the textbook summary.
About Alfred D. Chandler Jr.
Professor of business history at Harvard Business School; won a Pulitzer Prize for The Visible Hand and died in 2007.
Strategy and Structure established that firms adopt the multidivisional form once they diversify, and The Visible Hand showed how salaried managers displaced market coordination inside large American enterprises - the source texts for how conglomerates and holding companies are analysed. Scale and Scope extends the comparison to Britain and Germany and explains why different ownership patterns produced different corporate structures.
