Q.Discuss the following techniques of Scientific Work Study:

Here is the exam-ready breakdown of the Scientific Work Study techniques, strictly following the NCERT Class 12 Business Studies text.

Time Study (also called Work Measurement) determines the standard time required to perform a well-defined job. This is done by measuring the average time taken by a worker after adjusting for fatigue, delays, and other allowances. Its objective is to set fair performance standards and determine the number of workers needed.

Motion Study involves the close observation of the movements of a worker and their machine. The goal is to eliminate unnecessary motions (like bending, reaching, or searching) and identify the most efficient sequence of movements. This reduces wasted effort and improves productivity.

Fatigue Study examines the physical and mental strain a worker experiences during a task. The objective is to determine the length and frequency of rest breaks required to overcome fatigue. A worker who is rested works more consistently and with fewer errors.

Method Study is a systematic analysis of the entire way a task is performed. It aims to find the "one best way" of doing a job by eliminating unnecessary steps, combining operations, or changing the sequence of work. This leads to better utilisation of resources. …

Time Study — Measuring the "Right" Speed

Time study is the technique of determining the standard time required to perform a specific job. Taylor believed that workers often worked at an unnecessarily slow pace — what he called "soldiering" or deliberate go-slow. To fix this, he used a stopwatch to time each element of a task after breaking it down into its smallest parts.

The objective is not simply to clock someone. It is to establish a fair day's work — the amount of work that a qualified, well-trained worker can do under normal conditions without overexertion. Once this standard time is set, it becomes the benchmark for wage payment, production planning, and cost estimation.

Motion Study — Eliminating Wasteful Movements

Motion study is the study of the movements — such as lifting, putting down objects, sitting and changing positions — that a worker makes while doing a job. Unnecessary movements are identified and eliminated so the job takes less time and is done efficiently. As the NCERT chapter records, Taylor and his associate Frank Gilbreth reduced the motions in brick-laying from eighteen to just five, raising productivity to about four times, and Taylor used stopwatches and various symbols and colours to identify productive, incidental and unproductive motions.

The idea is simple: every unnecessary movement — bending, reaching, turning — adds to fatigue and slows down production. By redesigning the workplace layout, tools, and sequence of motions, the job can be done faster with less effort. For example, keeping frequently used tools within arm's reach eliminates the wasted motion of walking or stretching.

Fatigue Study — Understanding Human Limits

Fatigue study examines the physical and mental strain a worker experiences during a shift. Taylor recognised that a tired worker is a slow, error-prone, and unsafe worker. Fatigue is not just a personal problem — it directly reduces output and quality.

The technique involves observing how long a worker can sustain a given level of effort before performance drops. Based on this, rest breaks are scheduled at scientifically determined intervals. The length and frequency of breaks depend on the nature of the work — heavy manual labour needs more frequent rest than light assembly work.

Method Study — Finding the One Best Way

Method study is the systematic recording and critical examination of existing and proposed ways of doing work, with the aim of developing and applying the easiest and most effective method. It is broader than motion study — it looks at the entire process, not just individual movements.

It covers the entire process — from the procurement of raw materials right up to the delivery of the final product to the customer. Taylor devised the concept of the assembly line using method study, and the Ford Motor Company applied it very successfully. The objective is to minimise the cost of production while maximising the quality and satisfaction of the customer; for this, techniques such as process charts and operations research are used.

Simplification and Standardisation of Work

These two techniques are often discussed together because they reinforce each other. …
