WORK STUDY

Methods engineering includes worksimplification, job design, valueanalysis and the like.

Work study method was developed toimprove performance of a given work.

Work study is the body of knowledge

concerned with analysis of theworkmethods and the standard ofproposed work methods.


2/15

OBJECTIVES OF WORKSTYDY 1.To analyse the present method of

doing a job, systematically in order todevelop a new and better method

2.To measure the work content of ajob by measuring the time required todo the job for a qualified worker andhence to establish standard time.

3.To increase the productivity atminimum cost.

4. to improve operational efficiency


3/15

BASIC WORK STUDYPROCEDURE

1.Select the job or the process or the operation tobe studied. 2. Record all relevant facts about the job or

process. 3. Examine critically all the recorded facts. 4. Develop the new method for thejob/process/operation.

5. Measure the work content and establish thestandard time.

6. Define the new method for thejob/process/operation.

7. Install the new method. 8. Maintain the new method.

Method study methodsimprovement Prime objectives of method study is to

eliminate wasteful and inefficientmotions.

- To study the existing method- Develop improved method

- Work simplification

- Better product quality

- Better material handling

- Better working conditions

Motion study

Motion study is the science ofeliminating wastefulness resultingfrom using unnecessary, ill-directed

and inefficient motion.The aim of motion study is to find and

perpetuate the scheme of least waste

methods of labour.


8/15

Micro motion study

It is a valuable technique for makingminute analysis of those operationsthat are short in cycle.

Micro motions are THERBLIGS


9/15

Memomotion study

Developed by mundal.

It is a special form of micro-motionstudy

Multi-man and machine relationship

Work measurement

Measuring the work content of anyactivity under study.

Definition

work measurement is defined as theapplication of techniques designed toestablish the work content of aspecified task by determining the time

required for carrying out the task at adefined standard of performance by aqualified worker.


11/15

OBJECTIVES OF WORKMEAURESMENT Improved planning and control of

activities

More efficient manning of the plan

Reliable indices for labourperformance;

Reliable basis for labour cost control;

Basis for sound incentive schemes.


12/15

Techniques of WorkMeasurement

The main techniques used to measurework are:

Direct Time Study-centiminute stop

watch Synthesis Method

Analytical Estimating

Pre determined Motion TimeSystem(PMTS)

Work sampling or Activity Sampling or

Radio Delay Method

PRODUCTIVITY ANDEMPLOYEES Productivity: The amount of goods and

services produced with resourcesused

Formula:Quantity of goods and

Productivity = services produced

Amount of Resourcesused


14/15

MEASURINGPRODUCTIVITY

Partial productivity: Output in a given perioddivided by labour hours used in the period

Formula:Output in a given period

1.Partial productivity =Labour hours used in the period

Output in a given period

2.Total productivity =

Labour+Capital+Materials+Energyused in the same period


15/15

LABOUR PRODUCTIVITY

There are atleast three ways of measuring labourproductivity

Output per man-hour

Output

Labour productivity =

Man-hours used Labours hours per unit of Output

Total labour hours used


Ouput

Added value per unit of labour cost

Added value for the product


Total wages
