The factory probably did not train and encourage operators to sew in hanging condition. It was found when a check was done on a number of sewing operations which were executed in hanging condition in 8 UPS lines. Surprisingly, none were found to be in that condition. Even the large parts were not sewn in hanging condition in assembly section, as pieces were often hanged inverted.
This is a strong case of technology misuse; every factory should emphasize on judicious use of technology rather than a showcase
( to impress buyers or fellow manufacturers). The basic thumb rule for implementing overhead material handling system seems to be violated in all aspects in the factory.
