An Experimental Study on the Utility of Visual Type of Written Procedures

Abstract

In the previous study, we conducted the observation and evaluation experiments to subject the assembly work for an air control valve actuator, and we found that there were improvements in the workers performance at visual-type written procedure as compared to the conventional-type (mainly written text). In this paper, the observation and evaluation experiments to subject the assembly work for a small horizontal pump were carried out as another instrument. We evaluated from the point of how to read a written procedure, and the product of each indicator of three such as “awkwardness ” and the working time in each work step. As a result, we confirmed that visual-type written procedure was useful as compared to the conventional-type as with the previous study. Also, it was found that GAP-type PSF list that was derived in the previous study was able to utilize to support creating the visual-type written procedures, and to be assessed the improvements of written procedures from PSF perspective.
