Brown is perhaps best known for his collaboration with the organizational theorist Elliott Jaques on the Glacier Project, which Peter Drucker called "the most extensive study of actual worker behavior in large-scale industry". Sponsored by Glacier Metal Company and its Works Council during Brown's leadership, the project ran from 1948 to 1965, resulting in the development or discovery of felt-fair pay, stratified systems theory, timespan of discretion, levels of work, product pricing analysis and career progression trajectories. These ideas were described in the various books and articles written by Brown and Dr. Jaques. (See Bibliography.) Brown later attempted to use these processes in governmental affairs as a member of the House of Lords.
