Step 1: Understanding the Concept:
Frederick Winslow Taylor, widely recognized as the "Father of Scientific Management," aimed to replace the traditional, unorganized methods of management with systematic and objective approaches.
At the time of his work, industrial production was largely managed by intuition and "rule of thumb" methods, where managers made decisions based on personal experience or tradition rather than data.
Taylor proposed that every job could be broken down into its fundamental components and studied using scientific methods to identify the "one best way" to perform it.
The core idea was to maximize efficiency and minimize wasted effort through rigorous observation and experimentation.
Step 2: Detailed Explanation:
The principle "Science, not rule of thumb" is the foundational element of Taylor's philosophy.
In this context, the "rule of thumb" refers to the traditional methods where decisions were taken based on a manager's personal judgment, past practices, or trial-and-error.
Taylor pioneered the introduction of a "method of scientific inquiry" by suggesting that management should not rely on guesswork.
Instead, it should utilize specific scientific techniques to optimize work:
1. Time Study: Using a stopwatch to determine exactly how long a task should take under standard conditions.
2. Motion Study: Analyzing the physical movements of workers to eliminate unnecessary motions that cause fatigue and waste time.
3. Standardization: Establishing uniform tools and methods based on the results of scientific study.
4. Data Collection: Systematically recording output and conditions to find correlations between variables.
By applying these scientific inquiries, Taylor transformed the factory floor from a place of chaotic individual efforts into a synchronized, efficient system.
Option (B), "Harmony, not discord," focuses on the mental revolution between workers and management.
Option (C), "Cooperation, not individualism," emphasizes collective effort over competition.
Option (D), "Development of each person," focuses on training and scientific selection.
Only Option (A) specifically addresses the replacement of traditional "rule of thumb" with "scientific inquiry."
Step 4: Final Answer:
The principle that advocates for the use of scientific inquiry in management is "Science, not rule of thumb." Thus, (A) is the correct option.
