Method Study defined

According to British Standards Institution .

Method study is a 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 costs.


3/14

Method study along with Work Measurement is termed as

Work Study

Method Study aims to determine

the most effective method of performing a job

the most logical layout of manufacturing facilities

the smooth flow of men and material throughout the organisation

and the right placement of inspection stages

to enable processing of a job through the smallest possible

time and at least possible cost


4/14

Method study is concerned with how things aredone and is aimed quite simply at finding betterways of doing things.

Method study can be improved by five ways:

Eliminate unnecessary tasks

Simplify the process

combine tasks

Rearrange tasks

Reduce the number of operations


5/14

SELECT the work to be studied and define its boundaries.

RECORD the relevant facts about the job by direct observation and collect suchadditional data as may be needed from appropriate sources.

EXAMINE the way the job is being performed and challenge its purpose,place, sequence, person and method of performance.

DEVELOP the most practical, economic and effective method.

EVALUATE different alternatives to developing a new improved method, andcompare the cost-effectiveness of the selected new method with the currentmethod of performance.

DEFINE the new method in a clear manner and present it to those concerned,management, supervisors and workers.

INSTALL the new method as standard practice and train the persons involvedin applying it.

MAINTAIN the new method & introduce control procedures to prevent adrawback to the previous method of work.

Basic procedure for Method Study

Advantages of method study

Work simplification

Improved working method ( cheaper method)

Better product quality Improved equipment design

Better working conditions

Better material handling Improved work flow

Work Measurement

Work measurement is the application of techniques designed toestablish the time for a qualified worker to carry out specified jobs at adefined level of performance.

total time to manufacture a product is increased by:

adding undesirable features to product,

bad operation of the processes, and

ineffective time added because of worker and management.

All this leads to decreased productivity.


8/14

Work measurement (WM) is concerned with investigating, reducing

and eliminating ineffective time, whatever may be the cause.

WM is the means of measuring the time taken in the performance of an

operation or series of operations in such a way that the ineffective timeis shown up and can be separated out.

In practice, proving existence of the ineffective time is the most

difficult task.

After existence is proved, nature and extent is easy to see!


9/14

WM is also used to set standard times to carry out the work, so that

any ineffective time is not included later.

Any addition the standard time would show up as excess time and thus

can be brought to attention.

Since, standard times are set for all the activities through WM, it has

earned bad reputation amongst workers.

Major reason for that has been the initial focus of the WM methods,

which essentially targeted only the worker controllable ineffective

times. Management controllable ineffective times were ignored traditionally.

Process

1.Selecting the job.

2. Recording the specifications.

3. Breaking operation into elements.

4. Examining each element.

5. Measuring using stop watch.

6. Assessing the rating factor.

7. Calculating the basic time.

BT = Observed Time * operators time/ standard time8. Determining the allowances.

9. Compiling the standard time allowed time

Advantages

serves as a basis for methods analysis bycomparing the efficiency of alternative workmethods.

enables preparation of realistic work schedulesthrough accurate assessment human work inrelation to plant capacity for production andmaintenance planning.

helpful in balancing the work of different workers

provides an objective basis for wage incentiveplans by setting standards of machine utilisationand labour performance.


12/14

Work study

The application of systematic analysis to the work ofmen and machines so as to improve methods and toestablish proper time values for that work.

Objectives are to make the most effective use of plantand human effort and to establish a reasonable workload for those employed.

Investigates every aspect of existing or proposed workin order to find the best way of performing tasks.

Involves setting standard and solving problems relatedto bottlenecks, low morale, large amounts of defectivework and low productivity


13/14

Benefits of work study

Increased productivity and operational efficiency

Reduced manufacturing costs

Improved work place layout

Better manpower planning and capacity planning

Fair wages to employees

Better working conditions to employees

Improved work flow

Reduced material handling costs
