Match the following work study technique.

A-II, B-I, C-IV, D-III

A) MOTION STUDY- Motion study refers to the study of movements like lifting, putting objects, sitting and changing positions, etc., which are undertaken while doing a typical job. Unnecessary movements are sought to be eliminated so that it takes less time to complete the job efficiently. For example, Taylor and his associate Frank Gailberth were able to reduce motions in brick layering from 18 to just 5. Taylor demonstrated that productivity increased to about four times by this process.

B) METHOD STUDY- The objective of method study is to find out one best way of doing the job. There are various methods of doing the job. To determine the best way there are several parameters. Right from procurement of raw materials till the final product is delivered to the customer every activity is part of method study.

C) 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.

D) TIME STUDY- It determines the standard time taken to perform a well-defined job. Time measuring devices are used for each element of task. The standard time is fixed for the whole of the task by taking several readings. The method of time study will depend upon volume and frequency of the task, the cycle time of the operation and time measurement costs. The objective of time study is to determine the number of workers to be employed; frame suitable incentive schemes and determine labour costs.
