Basic procedure of Method Study
Method Study may be defined as:
“A procedure for examining the various
activities associated with the problem which ensures a systematic, objective
and critical evaluation of the existing factors and in addition an imaginative
approach while developing improvements.”
Procedure for Method Study:
Method study can be performed in
following six steps
1. Selection of Work/Job to be Studied:
This is one of the most important tasks
to select appropriate job, activity or situation for method analysis and mainly
it is a managerial responsibility. Method study and its implementation will
cost money.
Practically any activity is a potential
project for improvement but only those jobs should be selected when there are
some valid reasons for method study (like job/activity is unpopular or
considered dirty by workers). Maximum cost benefit is the normal objective.
2. Collection and Recording of Necessary Information:
Obtain the facts about the present method
of doing the job and record them. In order to improve an activity or procedure
the factual information is collected from the place where the job under study
is being executed by direct visual observation.
This can be done by:
(i) Recording movement of machines or
materials.
(ii) Recording the critical procedure in
the job.
(iii) Recording the operator’s
performance.
(iv) Recording the path of movement of
workers,
(v) Recording the path of movement to
improve workplace layout.
(v) Recording the scrap generated.
There are many standardized techniques (i.e.,
charts, diagrams, graphs etc.) available which may be used for proper recording
and presentation for further analysis. The choice of technique depends on the
type of information which is to be recorded.
This is an important step since the
improvement in existing method or development of new method depends on how
exactly the facts about the existing method have been recorded.
3. Critical Examination of the Existing Method:
Now examine the facts critically. This is
a key step in the whole study. The information available in the form of chart
and graphs after step II can now be thoroughly studied and analysed in order to
detect the production stages where improvement in the method is possible. This
is achieved by questioning the different activities of the process in a
systematic logical and objective manner.
These questions can help in the development of
new method by getting the answers for:
(i) What should be done?
(ii) When should be done?
(iii) Who should do it?
(iv) Where should it be done?
(v) How should it be done?
The following improvements are possible on the
basic of answers to these questions:
(i) Improvement in material flow.
(ii) Improvement in working conditions.
(iii) Improvement in manufacturing
techniques.
(iv) Improvement to clerical routine.
(v) Reduction in material waste.
In this way a well conducted examination
will determine the purpose, place, sequence of these activities, the person
performing them and the resources by which it can be performed so as to select
the best/optimum out of the possible alternatives.
4. Develop the New Improved Method:
The analysis of existing work method can
provide a starting point for a synthesis of suggested improvements in job
performance. The technique specially designed for improving work method is
called the process improvement formula.
The four steps of the formula are:
(i) Eliminate the unnecessary activities
(ii) Combine two or more activities
(iii) Sequence the various activities
properly and
(iv) Simplify the activities.
Complete elimination of unwanted
activities is the most important step in developing an improved method. If
elimination is not possible then possibility of combining the different
activities should be explored. The next strategy in development stage is to
identify scope of changes in the sequence of operations or activities.
The last and most important plus
expensive step in process of method development is the simplification of
activities in order to allow the operator/worker to complete the job more
quickly and easily by reducing the number of operations, reducing or
eliminating the delays and storage etc.
Finally, after selecting the work method
to be adopted, certain amount of experimentation will be required to locate and
eliminate snags if any.
Specify the improved method. It is
essential that the selected method be described fully and in a systematic
manner.
Specifications of the selected method
accomplish several purposes like:
(i) Communication of the method to the
management for its approval.
(ii) Communication to those concerned
with its implementation like instructions to workers and so far as the machines
and layout are concerned.
(iii) Provision of an official record of
the method.
The new method should possess the following
aspects:
(a) Full use of worker’s body,
(b) Arrangements of workplace and
(c) Design of tools and Equipment.
The acceptance of new method will mainly
depend upon the cost benefit, trade unions approach, working hours and security
requirements etc.
5. Install the Improved Method:
This involves training of those who are
going to utilize the new method. Cooperation from both supervisory staff and
operators is essential to the successful installation of any proposed and
selected method. So the installation of the new method should then be entrusted
to some responsible person.
The method implemented can be further
improved by way of continuous observations and discussions. The trial runs may
be carried out during which minor modifications may be made to facilitate
working.
Any method selected is ultimately to be
utilized by the employees in an environment created by the management. So
employees and management should be subjected to intensive analysis so that the
proposed method is operated in the best possible manner.
Installation phase of the method study is
complete as soon as the newly installed method starts working smoothly and
satisfactorily and provides encouraging result (such as time saving and scrap
reduction etc.).
6. Maintain the Improved Method:
Even after the workers have been trained
and requisite changes in machines and layout have been incorporated, there is
no guarantee that the method will be used the way it was designed.
The proper functioning of the installed
method is ensured by periodic checks and verifications. The purpose of checks
and reverse is to determine if the method being adopted and practiced is the
same or it has some deviation from the selected one.
Reasons for deviation if any should be
explored and the required changes may be incorporated in the procedure being practiced so as to revert back to the authorized or selected one.
Views of persons concerned (like operators and supervisors) with the installed method can be of much help in exploring further improvements in the system. Therefore, the method should be reviewed at intervals to provide allowances for any changes.
