Micro Motion Study Technique: Introduction, Definition, Purpose and Advantages!


Micro motion study method is best adapted for short-lived and recurring hundreds of time operations or activities. These are the operations or motions that require very little time and for these motions it is quite difficult to accurately measure time and due to repetitive operations the time required by these motions can not be ignored.

It is important to go into more information in such operations in order to figure out which motion and effort can be prevented. All this is done to create the finest feasible motion model so that with minimal attempt and exhaustion the user can execute the activities continuously.


"Thus micro movement study is the technique of recording and analyzing the timing of the basic elements of an operation with the aim of achieving the best method of performing the operation." Such short-term activities involve rapid movement of limbs that can not be correctly researched and scheduled using two hand-held procedure maps. This is because microscopic information such as separate operations, inspection and transportation etc. are recorded. It is not enough to study such microscopic motions in brief cycle repetitive employment.

For microscopic movements, short cycle activities need to be investigated, e.g., the procedure of pulling up a nut from the bin and its fixation comprises of three hand movements, namely reaching for the nut, grasping nut and moving hand back to installation place. Such thorough assessment helps to create the finest feasible movement model and thus allows the user to constantly conduct multiple activities with minimal attempt and fatigue.

Micro motion study is one of the most precise working evaluation methods used to improve the job. It uses movie photos of the various operations or movement, so with camera assistance. This device can measure and record up to 0.0005 minutes of very small time.

The method is regarded as "MICR-MOTION STUDY" when using the image camera. The film's movement time information is transmitted to the simo graph. For workplace design or process enhancement purposes, the simo graph information can be further evaluated.

Fran Gilbreth created this method, considering that an procedure comprises of minute components that may be repetitive or non-repetitive. He called these components THERBLIG (when spelt bank term is Therblig after his name Gilbreth).

Purpose of Micro Motion Study:

For the following purposes it can be used:

1. To research the nature and route of movement in order to obtain the procedure components.

2. To research the machine's and operator's operations.

3. To provide instruction to employees or carriers on movement; economy in order to avoid excessive worker movement.

4. Studying the connection between the operator's operations and the device.

5. Keeping a continuous record of the most effective manner to perform a potential reference assignment.

6. To acquire movement time information for different components to develop synthetic time standards.

7. For conducting technique and time survey research.

Advantages of Micro Motion Study:

It has the following important advantages:

1. It offers a continuous record of film movement study.

2. A large number of operators can see the procedure at any time, even after the movement study work has been completed.

3. The distinction between the current and the suggested method can be readily revealed by films.

4. Films can be shown at any required velocity to a big workforce.

5. Compared to stop watch time study, it offers very precise time for each procedure or movement.

6. It helps to analyze the prevalent method in detail and accuracy.
