"Standardisation refers to the process of setting standards for every business activity; it can be standardisation of process, raw material, time, product, machinery, methods or working conditions". The phenomenon of standardisation was specified by:

The correct option is F.W. Taylor.

Explanation:
Standardisation is a fundamental technique of Scientific Management, a management theory pioneered and developed by Frederick Winslow Taylor (F.W. Taylor). Taylor believed that to achieve maximum efficiency and eliminate wastage of resources, business activities must be systemised by setting clear benchmarks or standards for every aspect of production and operations.

According to Taylor, standardisation refers to the process of establishing predetermined standards for:
• Methods and Processes: Determining the "one best way" to perform a job through scientific analysis.
• Tools and Equipment: Specifying the exact machinery and tools required to minimize physical strain and maximize output.
• Working Conditions: Setting uniform standards for illumination, ventilation, and safety in the workplace.
• Raw Materials and Quality: Ensuring that all input materials are of a uniform, high grade to produce standard quality goods.

In contrast, the other management scholars are associated with different contributions:
• Henry Fayol is famous for his 14 principles of general or administrative management.
• Abraham Maslow is known for his hierarchy of human needs theory in motivation.
• Harold Koontz is recognized for his work in defining management functions and organizing management theories.
