2. MICRO-MOTION ANALYSIS
Micro motion analysis is the study of
fundamental element or subdivision of an
operation .
Micro motion study provides a valuable
technique for making minutes analysis of those
operation that are short in cycle contain rapid
movement and involve high production over a
long period of time.

3. • Applicable for operations with very short cycles
which are repeated thousands of times.
• Goes into greater details to determine where
movements and efforts can be saved and to
develop the best possible patterns of
movements.
• Enables operators to perform the operation
repeatedly with minimum effort and fatigue.
• The technique used for this typically involves
filming the operation and hence is known as
micromotion study.

4. • Based on the idea that human activity can
be divided into movements or group of
movements (therbligs) according to the
purpose for which they are made.
• The therbligs cover movements or reasons
for the absence of movement.
• Each therblig has specific color, symbol and
letter for recording purposes.
• Therbligs refer primarily to motions of the
human body at the workplace and to the
mental activities associated with them.

5. Operations with very short cycles
and repetitive cycles need greater
details to analyze it for saving
motions and efforts (i.e. planning
for lesser fatigue). This goal can
be achieved through micro-motion
studies.
MICRO means ''small".
Thus here we study the
motions in terms of
THERBLIGS

6. On analysing the result of several
motion studies conducted, Gilbreths
concluded that any work can be done
by using a combination of some or all
of 17 basic motions, called Therbligs
(Gilbreth spelled backward).

• They permit a much more precise and detailed description of the
work than any other method described.
• Considerable practice is required in identification of therbligs before
they can be used for analysis with confidence.
