The following are techniques of Scientific Management, except:

1. Functional foremanship
2. Standardisation
3. Differential piece wage system
4. Initiative

Option 1 -> Functional foremanship is a technique where 8 specialized foremen supervise workers for different functions, introduced by Taylor under Scientific Management.

Option 2 -> Standardisation involves standardizing tools, methods, materials, and working conditions to ensure uniformity and efficiency - a core Scientific Management technique.

Option 3 -> Differential piece wage system is Taylor's wage incentive plan where efficient workers are paid higher rates and inefficient ones lower rates to motivate productivity.

Option 4 -> Initiative is a principle of management by Henri Fayol (not Taylor), which encourages employees to take initiative and think creatively - NOT a technique of Scientific Management.

Hence, Option 4: Initiative -> Initiative is one of Fayol's 14 Principles of Management that emphasizes encouraging employees to develop and implement their ideas. It is not a technique of Taylor's Scientific Management, which focused on work study, standardization, functional foremanship, and wage incentive systems -> correct
