As manufacturing concerns grew in size during the era of mass production, the need for a hierarchy of supervisors and managers became essential for several reasons:
- Operational Complexity: The increasing scale and complexity of manufacturing operations required specialized managerial-level employees to oversee distinct functions, such as accounting, engineering, human resources, marketing, and distribution.12
- Directing the Workforce: Formal bureaucratic structures and close supervision were necessary to discipline and direct a large, often unskilled or semiskilled labour force.12
- Separation of Authority: Influenced by scientific management, companies established a clear separation between supervisors, who determined how work should be organized, and production employees, who executed those tasks.2
- Monitoring and Coordination: As departments became more specialized, a large cadre of middle managers was required to generate the performance and financial reports necessary for top executives to monitor and direct company-wide operations.2
