Work Study

It is the systematic investigation of human activities necessary to perform a given task economically.

Work study techniques can be classified in two areas:

Method study Work measurement

• Method Study:It is the systematic recording and critical examination of existing and proposed ways of

doing work as a means of developing and applying easier and more effective methods and reducing cost.

• Work Measurement:It involves the application of the time study technique designed to establish the time for a

qualified worker to carry out a specified job at a defined level of performance.

Difference between Method Study and Work Measurement:Method study is concerned with the relation of work content of a job or operation, while

work measurement is mostly concerned with the investigation and reduction of any inefficient time associated with it.

The Objectives Of Work Study

• To find out economical way of doing work.

• Standardizing the methods, materials, tools and equipment.

• Accurately determining the time required by a qualified

• Assisting In training of the worker On new

improved methods.

Method Study

• Objectives of Method Study

a) To improve the process and procedure.

b) To improve the workplace layout.c) To design the efficient equipment.d) Economy in human effort and

reduction in unnecessary fatigue.e) Improvement in the use of materials,

machines and manpower.f) Development of better working

environment.

• Procedure of Method Study

a) Select the job to be studied.b) Record the relevant facts.c) Analyze or examine these data/facts.d) Develop an improved method.e) Define the new method.f) Install the new improved method.g) Maintain the new improved method.

Economic AnalysisThe new practice should not be installed

without verifying the economic benefit.

Method Study Flow Chart

Method Study

a) A Select the Job:the job with following characteristics is

more suitable for method study:

i. Job with large work content.

ii. Jobs with long delivery schedules.

iii. Jobs with large man or machine idle time.

iv. Jobs with poor interest of workers.

v. Jobs with large variation in output.

vi. Jobs with quality variation.

• Some other factors

i. Technical Consideration

ii. Human reaction

Method Study

b) Record the Facts and DataThe most commonly used techniques

used for this purpose are chats and diagrams. Charts can be classified in three types:

1) Process Charts

2) Activity Charts

3) Movement Charts

Another division of charts is as follow: Charts not recorded to time scales Charts recorded to time scales

1) Process Chartsi. Operation or outline process chart.ii. Flow process chart.

2) Activity Chartsiii. Man-machine chartiv. Left hand-right hand activity chart

3) Movement Chartsv. Travel chartsvi. Flow diagramvii. String diagram

Method Study

In process charts activities are classified as operation, inspection, transport, delay and storage. Various symbols are used to identify each activity.

Operation-Oindicate the main steps in a process,

method or procedure.

Inspection-Indicate an inspection for quality and/or

check for quantity.

Transport-Indicate the movement of workers,

materials, or equipment from place to place.

Delay-DIndicate the delay in the sequence of

events.

Storage-Indicates the controlled storage.

Method Study

• Operation Process Chart (Outline Process Chart)

It gives an overall picture by recording in sequence only the main operations and inspections.

• Flow Process ChartsIs a process chart for setting out the

sequence of the flow of a product or a procedure by recording all events under review using the appropriate process chart symbols.

• Man-Machine Charts or Activity Charts:

These charts may include:

1 Man- 1 Machine charts

1 Man-2 Machine charts

1 Man-3 Machine Charts

2 Men-1 Machine chart and so on

Left-hand Right-hand ChartsMicro motions are to be recorded.

Method Study

• Travel ChartIs a tabular record for presenting

quantitative data about the movements of the workers, materials or equipment between any number of places over any given period of time.

• Flow DiagramThey are made on the scale plan of the

work place.

• String DiagramsA string diagram is a scale plan or model

on which a thread is used to trace the path of the worker movements during specific period of study.

Method Study

d) c) AnalyzeThe data regarding the existing method is examined systematically. stepwise investigation is made of each

activity. The areas of investigation includes:PurposePlacePersonSequencemeans

Developthe analysis of existing method leads to the development of an alternate method.

e) Define After practical test the activities of new method are defined as written standard.

f) InstallThe workers are trained on the improved method before installing the new improved method.

g) MaintainPeriodic follows up of the standard or improved method is necessary to ensure that the method is actually being

practiced as defined.
