Although it has not been recognized very clearly, Alfred Chandler offers a dual definition of modern business. One definition focuses on the formation of “managerial hierarchies;” this refers to the rise of professional managers, a development that eventually leads to the separation of management and ownership. The advent of the managerial firm, or managerial capitalism, symbolizes modern business. Chandlers other definition focuses on management structure and emphasizes the U-form (Unitary-form) or M-form (Multi-divisionalform), both of which are organizational types closely associated with the development of modern, large-scale firms. The modern firm usually has the characteristics of a managerial organization and employs either the U-form or M-form (typically the latter) structure.
