The query requires identifying which of the given choices represents a principle established by Henri Fayol, a French engineer and mining director recognized for his general theory of business administration. Fayol is credited with formulating 14 Principles of Management. An examination of the options is as follows:
- Cooperation, not Individualism: This principle is attributed to Frederick W. Taylor's scientific management, not Fayol.
- Scalar Chain: This is a principle advocated by Fayol. It defines a hierarchical line of authority from top to bottom within an organization, which should be adhered to during decision-making to ensure order and effective communication.
- Functional Foremanship: This concept is also associated with Taylor's scientific management, not Fayol.
- Method Study: This is a technique within scientific management focused on analyzing work methods to enhance productivity, rather than a principle of Fayol's.
Consequently, the correct response is the Scalar Chain, aligning directly with one of Henri Fayol's established principles.
