Work Study: Meaning, Objectives and Scope

Updated 10 October 2026 · Fact-checked

Work study is a systematic way of examining how work is done so that resources are used better and productivity rises. It has two parts: method study, which finds the best way to do a job, and work measurement, which finds the time that job should take. Answers follow the objective, scope, procedure and benefit sequence.

Understand Work Study: Meaning, Objectives and Scope

Work study is a management technique that looks at human work in all its contexts. It studies the factors that affect efficiency and economy, and it does so systematically. The aim is to find improvements without heavy new investment in plant or people.

Work study has two techniques. Method study records and critically examines the present way of doing a job, then develops a simpler, cheaper and easier method. Work measurement (also called time study) finds the time a qualified worker needs to do the job at a defined level of performance. Think of it as: first fix the method, then measure the time. If you measure first, you only measure waste.

Work study is also called work-study engineering or, loosely, time and motion study. Strictly, motion study belongs to method study and time study belongs to work measurement. Together they are a direct route to higher productivity, which means more output from the same inputs.

The objectives are to improve methods and processes, to improve layout and use of plant, materials and manpower, to reduce unnecessary movement and fatigue, to set fair time standards, and to support planning, costing and incentive schemes. The scope is wide. It applies in factories, offices, stores, hospitals, banks and service units, wherever people carry out repeated work.

The benefits include higher productivity, lower unit cost, better use of capacity, improved working conditions and safety, a base for standard costing and wage incentives, and more reliable delivery schedules. It also gives workers a clear, fair standard of what a day's work is.

Key rules to remember

Work study structure: Work study = Method study + Work measurement; Method study decides how the job is done. Work measurement decides how long it should take.
Basic procedure (SREDDIM): Select → Record → Examine → Develop → Define → Install → Maintain; A common seven-step version. Some books combine steps. Learn the order and give a one-line purpose for each.
Productivity: Productivity = Output ÷ Input; Work study raises this ratio by cutting wasted input or raising output.

How to solve Work Study: Meaning, Objectives and Scope questions

Most questions ask you to define, state objectives, explain scope or benefits, or distinguish its parts. Use the same frame every time.

1Read the verb: define, explain, distinguish, discuss or list. It sets the depth.
2Open with a one-line definition: systematic examination of work to improve productivity.
3Name the two techniques, method study and work measurement, with a line on each.
4State objectives or scope as short bullet points. Use 5 to 7 points for a 14-mark answer.
5Add the procedure (select, record, examine, develop, define, install, maintain) if the question asks how it is done.
6Give benefits to the organisation and to workers.
7Close with a short example, such as a packing line or a billing counter, to show application.

Quickest way: Definition, two parts, objectives, benefits

When to use it: Short notes and 4 to 8 mark questions where time is limited.

Write the definition in one sentence.
Write 'two techniques' and give one line each.
List four to five objectives in bullets.
List three to four benefits.
For MCQs, link keywords: 'best method' means method study; 'standard time' means work measurement.

Common mistakes in Work Study: Meaning, Objectives and Scope

Treating work study and method study as the same thing.
Both words appear together in the chapter.
Fix: Remember that method study is only one half. Work study also includes work measurement.
Saying work measurement comes before method study.
Students think timing is the first step.
Fix: Improve the method first, then set the standard time for the improved method.
Writing that work study needs large capital investment.
Confusing it with plant modernisation.
Fix: State that it improves output mainly by better methods, with little or no new investment.
Confusing time study with motion study.
'Time and motion study' is used as one phrase.
Fix: Motion study belongs to method study. Time study belongs to work measurement.
Listing the procedure steps out of order or without purpose.
Memorising letters without understanding.
Fix: Learn the logic: choose the job, record facts, challenge them, design the new way, set standards, implement, then sustain.
Limiting scope to factory shop floors.
Textbook examples are mostly manufacturing.
Fix: Mention offices, hospitals, banks, stores and other service operations.

Worked examples

Example 1

Define work study. Explain its objectives and its two techniques. (Short answer, 7 marks)

Show the solution

Definition: work study is the systematic examination of the way work is done, in order to find the most effective use of resources and raise productivity.
Technique 1: method study records and critically examines existing methods and develops a better one.
Technique 2: work measurement finds the time a qualified worker takes to do a job at a defined performance level.
Objectives: improve methods and processes; improve layout and use of plant, materials and labour; reduce wasted movement and fatigue; set fair time standards; support planning, costing and incentives.
Link: method study is done first, so that the time set is for the best method.

Answer: Work study is the systematic examination of work to improve productivity. It consists of method study (finding the best way) and work measurement (finding the standard time), with objectives of efficiency, economy, fair standards and better working conditions.

Example 2

A packing unit in Pune wants to apply work study to its packing line. State the procedure it should follow and one likely benefit at each stage.

Show the solution

Select: choose the packing line because it has delays and high labour cost. Benefit: effort goes where gains are largest.
Record: note the present method with a process chart. Benefit: facts replace opinion.
Examine: question the purpose, place, sequence, person and means of each activity. Benefit: unnecessary steps are exposed.
Develop: design a simpler layout and sequence, and time it. Benefit: lower effort and cycle time.
Define: write down the new method clearly. Benefit: everyone follows one standard.
Install: train workers and start the new method. Benefit: smooth adoption.
Maintain: check regularly that the method is followed. Benefit: gains last.

Answer: The unit should follow select, record, examine, develop, define, install and maintain, ending with a standard time set for the improved method. The overall benefit is higher output per worker and lower cost per unit.

Exam tips

Always mention both method study and work measurement, even if the question only says 'work study'.
In 'distinguish' questions, use a two-column comparison in points: purpose, focus, output, tools. Keep it in plain lines if space is short.
For MCQs, 'standard time' points to work measurement and 'best method' points to method study.
Add one practical example from a factory or an office to lift a theory answer.
Write the procedure steps in order, with one line of purpose each.

Practice questions from Control Measures - Time and Motion Study, Method Study, Work Study

Work Study: Meaning, Objectives and Scope: frequently asked questions

What is work study in simple words?

It is a systematic way of studying how a job is done and how long it should take. The goal is to find a better method and a fair time standard so that productivity rises.

What is the difference between method study and work measurement?

Method study finds the best way to do a job by recording and examining the present method. Work measurement finds the time a qualified worker needs to do the job by that method. One sets how, the other sets how long.

Is time and motion study the same as work study?

Not exactly. Time and motion study is a popular phrase that joins motion study (part of method study) and time study (part of work measurement). Work study is the wider term covering both.

What are the main benefits of work study?

It raises productivity, reduces unit cost, improves layout and working conditions, and gives standards for costing and incentive wages. It usually needs little capital investment.
