Question 4: Discuss the following techniques of Scientific Work Study:
a. Time Study
b. Motion Study
c. Fatigue Study
d. Method Study
e. Simplification and standardisation of work
Answer:
(a) Time study: In this technique the standard time is decided to perform a well defined job. The standard time is fixed for a task by taking several readings. This method of time study is depending upon the volume and the frequency of the task. And once the standard time is set for any particular task then that task should be assigned to the workers and on the basis of standard time we can determine the efficiency of the workers. If any worker completes the particular task within the standard time then that worker should be considered as efficient and if any worker cannot accomplish the task within standard time then he will be considered as inefficient. The objectives of the time study are:
- To determine the number of workers/employees should be employed to do any particular task.
- To determine the suitable incentive schemes.
- And to determine the cost of labour.
(b) Motion study: Motion study means study of movements like lifting, putting objects, sitting and changing position etc. while doing any particular job. And under this study all the unnecessary movements are eliminated so that it takes less time to complete the job efficiently. Taylor used stopwatches and various symbols and colors to identify different motions. And by this study he designed suitable equipment and tools to educate workers on their use and to minimize the unproductive motions..
(c) Fatigue study: Fatigue study determines the amount and frequency of rest intervals is required for completing the task. A person is bound to feel tired physically and mentally if he/ she does not take rest while working. If the worker doesn’t take rest while working then it reduces his/her efficiency. The rest intervals help the worker to regain their stamina to work again and they can perform their job efficiently. And this will increase productivity.
(d) Method study: There are various methods to perform the job. The objective of method is to determine the best way of doing the job. To determine the best way there are various parameters. Each and every activity right from procurement of raw material to delivering the finished goods is a part of method study. And this will help in minimizing the cost of production and maximizing the quality and satisfaction of the customer.
(e) Simplification and standardization of work: Standardization refers to the process of setting standard for each and every business activity and that is standardization of process, raw materials, time, products, machinery, methods or working conditions. The main objective of this method is to establish standards for performance of men and machines.
Whereas simplification aims to eliminate superfluous/unnecessary varieties, size and dimensions. It eliminates all unnecessary diversity of products. And this will give rise in saving the cost of labour, machines and tools. This technique helps in fuller utilization of equipment and increasing turnover.
