2. METHOD STUDY
“Method study is the systematic recording & critical
examination of existing & proposed ways of doing work as a
means of developing & applying easier & more effective
methods of reducing cost.”
 To eliminate unnecessary operations
 To achieve the best method of performing the operation

3. Objectives of method study:
The study is conducted to achieve the following objectives—
 to bring improvement of work processes and procedures
 to economize human efforts and to reduce unnecessary fatigue
 to improve the usage of materials, machines and manpower
 to develop better physical working condition and environment

4. Procedure for method study
Method study includes the following Steps:
 Select – choosing the job or procedure to be studies
 Record – collect all the relevant facts about the present or proposed
method.
 Examine -critically scrutinizing these facts in an orderly sequence using
the techniques best suited to the purpose
 Develop – develop the best possible method
 Install -- practice the developed method
 Maintain – checking the new standard practice by proper control
procedures and regular routine checks.

5. Recording Techniques

14. MICRO-MOTION STUDY
 Micro-motion study provides a technique for recording and timing an activity.
It is a set of techniques intended to divide the human activities in a groups of
movements or micro-motions(called Therbligs) and the study of such
movements helps to find for an operator one best pattern of movements
that consumes less time and requires less effort to accomplish the task.
Therbligs were suggested by Frank O. Gilbreth, the founder of motion study.
Micro-motion study was mainly employed for the job analysis.
 The Therbligs are micro-motion study involves the following steps:
1. Filming the operation to be studied.
2. Analysis of the data from the film.
 The recording of the data through SIMO chart is done as micro motion chart.

16. MEMO MOTION STUDY
 It is a form of time lapse photography which records activity by use of
cine camera adopted to take picture at longer intervals than normal
 It is effective method for mass production system
 Speed is 1-2 frames/sec instead of 24 frames/sec as used in micromotion
study
 Economical than micromotion study

17. MEMOMOTION VS. MICROMOTION
STUDIES
 Key difference between Macromotion and Micromotion studies are as
under :
 Motion studies are performed to eliminate waste. Before any
improvement in quality or quantity of output, any study of operations
time, any scheduling of work or balancing of workload or any calculation
of standard time, a study of the current and proposed method is
required. Studies of overall factory flow or process, called macromotion
studies, and then additional studies of detail or operations, called
micromotion studies, should be completed for a project.
