Step 1: Concept
F.W. Taylor developed the principles of Scientific Management focusing on shop-floor efficiency, whereas Henri Fayol developed general principles of management.
Step 2: Meaning
We need to identify which of the given options belongs to Fayol's general management theory rather than Taylor's scientific theory.
Step 3: Analysis
• "Science, not rule of thumb" is Taylor's core principle emphasizing scientific study over intuition.
• "Harmony, not discord" is Taylor's principle advocating for mutual understanding between workers and management.
• "Maximum output instead of restricted output" is Taylor's principle focusing on maximizing productivity.
• "Stability of Tenure of personnel" is one of Henri Fayol's 14 principles of management, which states that employees should not be moved frequently from their positions.
Step 4: Conclusion
Since "Stability of Tenure" is a principle given by Fayol and not Taylor, it is the correct answer.
Final Answer: (B)
