Read the following passage and answer the question.

Mona is a production manager in a company. She wants to improve performance of shop floor level in the factory. For this, she takes many steps. She separates planning and execution functions and appoints planning in-charge and production in-charge under her subordination.

She eliminated superfluous varieties, sizes and dimensions of product lines. She keeps a continuous watch on body movements of workers of the factory and places them in three categories of productive, incidental and unproductive movements. She instructs workers to discontinue unproductive movements.

On the basis of a study she decided the amount and frequency of rest intervals for workers.

All these steps gave positive result and factory production increased significantly in both quality and quantity teams.

Name the technique of scientific management used by Mona for deciding the amount and frequency of rest intervals to workers of the factory.

Fatigue Study

The correct answer is option (1) : Fatigue Study.

Fatigue Study- A person is bound to feel tired physically and mentally if she/he does not rest while working. The rest intervals will help one to regain stamina and work again with the same capacity. This will result in increased productivity. Fatigue study seeks to determine the amount and frequency of rest intervals in completing a task. For example, normally in a plant, work takes place in three shifts of eight hours each. Even in a single shift, a worker has to be given some rest interval to take her/his lunch, etc. If the work involves heavy manual labour then small pauses have to be frequently given to the worker so that she/he can recharge her/his energy level for optimum contribution. There can be many causes for fatigue like long working hours, doing unsuitable work, having uncordial relations with the boss or bad working conditions etc. Such hindrances to good performance should be removed.
