Method study 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 costs.
Its aim is to find best possible manufacturing procedure
that requires least time and less fatigue to worker.
Used to analyze
Movement of body, people, or material
Activities of people & machines

Method study is a technique to reduce the work
content mainly by eliminating unnecessary movements
by workers, materials, or equipments.
However, even after that, there could be unnecessary
time taken for the process because of lack of
management control or inaction of worker.
Explaination of Method study:
◦ Various charts to record movements.
◦ i.e L-R hand process charts, therblig-gilbreth chart
etc.

Procedure to accomplish method study, called "SREDIM"
shall be as follow:
1. Select: the job or operation that needs improvement,
2. Record: all facts, how work is done by chart methods,
3. Examine: every aspect of the job by asking; what, why,
where, when, who and how
4. Develop: review ideas, eliminate, simplify, combine, re-
arrange, make new method which more safe, chart new
method, submit for approval,
5. Install: the new method, consider best time to introduce,
convince all, train users,
6. Maintain: check frequently, match results, correct
deviations.

(man-type, material-type and equipment-type)(man-type, material-type and equipment-type)
These are the chart that use symbols and
description to show the sequence of work. The
process, then, show what is happening at
different stages. The distances and time may be
given.

component or when material is to be move from one
place to another place.
Occurs when an object is examined for identification.
Occurs when the hand holds an object so that other
hand may work on the object.
