Concept:
Scientific Management was developed by Frederick Winslow Taylor with the objective of increasing efficiency and productivity in industrial operations.
Taylor introduced several techniques to improve production efficiency, including:
- Time Study
- Motion Study
- Method Study
- Fatigue Study
Among these techniques, Method Study focuses on identifying the best possible way of performing a job.
Step 1: Understanding Method Study.
Method Study refers to the systematic analysis of production processes to determine:
- The best sequence of operations
- Proper arrangement of machines
- Proper placement of workers
- Efficient handling of raw materials
- Reduction of unnecessary activities
Its primary objective is to improve efficiency and minimize wastage of time, effort, and resources.
Step 2: Analyzing the situation given in the question.
The question states that Cross Ltd. follows assembly line production involving:
- Sequence of operations
- Place for men
- Arrangement of machines
- Handling of raw materials
All these activities are directly related to determining the best method of performing work.
Therefore, the company is applying Method Study.
Step 3: Why other options are incorrect.
- Time Study: Determines the standard time required to perform a task.
- Motion Study: Analyzes body movements involved in work to eliminate unnecessary motions.
- Fatigue Study: Determines rest intervals to reduce worker fatigue.
Since the question focuses on arrangement and sequence of production activities, these options are not appropriate.
Step 4: Final conclusion.
The technique of scientific management used by Cross Ltd. is:
\[
\boxed{\text{Method Study}}
\]
