Explanation:

[ (a) Time Study ]

• In this technique Taylor emphasised on setting a standard time limit for completing any particular job. With the help of time measuring tools, considerable readings were taken for the time taken to complete a task. On the basis of this a standard time limit is set for each task. This helped in deciding the number of workers to be employed for the task, determining their wages, etc. For example, if, on the basis of observations it is determined that one person can finish making 1 shirt in two hours then, in a working day of 8 hours, each worker should make 4 shirts.

[ (b) Motion Study ]

• As the name suggests, motion study refers to the study of motion (movements) involved while undertaking a task. This technique aims at removing the unwanted actions/motions so that the work can be completed in a lesser time. Taylor along with his associate Frank Gailberth observed the motions of a worker and categorised them as productive, incidental and unproductive. They demonstrated that by eliminating the unproductive movements productivity can be increased. For example, in brick layering they demonstrated that productivity increased by nearly 4 times by reducing the motions from 18 to 5.

[ (c) Fatigue Study ]

• This technique is regarding requirement of rest or break during the work. If a worker works continuously physical and mental fatigue sets. This reduces his/her efficiency. Thus, the worker requires rest or break. Fatigue study identifies the intervals required while completing a task. It suggests that standard break timings should be decided for improving the working performance of workers.

[ (d) Method Study ]

• This study aims at finding out the best method of completing any work. It takes into account each and every activity involved in the task. It helps in reducing the costs and maximising the satisfaction of the customers. Assembly line production, used by Ford Motors is a popular example of method study.

[ (e) Simplification and Standardization of Work ]

• Taylor holds up standardization as the very basis of techniques of scientific management. Standardization as the word suggests implies setting of milestones or benchmarks for any work or activity. Various other techniques by Taylor, such as method study, fatigue study and time study are also based on the concept of standardization.
