Who gave the concepts of 'mental revolution' and 'Harmony, Not Discord'?

Option 1 -> Peter Drucker is known as the father of modern management and contributed concepts like Management by Objectives (MBO) and decentralization, not these specific principles.

Option 2 -> Fredrick Winslow Taylor, the father of Scientific Management, introduced 'Mental Revolution' (cooperation between workers and management) and 'Harmony, Not Discord' (one of his four principles emphasizing cooperation over conflict).

Option 3 -> Henri Fayol developed the 14 principles of management and administrative management theory, but not these specific concepts.

Option 4 -> Philip Kotler is recognized as the father of modern marketing and is not associated with these management principles.

Hence, Option 2: Fredrick Winslow Taylor -> He advocated for 'Mental Revolution' which emphasized a complete change in attitude from both workers and management toward mutual cooperation, and 'Harmony, Not Discord' as a core principle stating that management and workers should work together harmoniously rather than in conflict, both being fundamental concepts of his Scientific Management theory -> correct
