Reducing variation at the measuring stage for a quality inspection process in material handling stations

© 2019, IEOM Society International.We addressed the inspection process of a critical product in an industrial refrigeration company. Using DMAIC methodology and it's tools, through an integral proposal that included the implementation of new documentation, visual aids and training courses, it was expected to achieve the standardization of the inspection process as well as a better quality of it. Preliminary results shown a 125% increase in the Kappa index for agreement levels of an attribute Gage R&R (from weak to moderate), as well as a 10% reduction in type II error (using defective product) and a reduction of 75% in scrap after one implementation. A control plan was left with the company to maintain improvements, expecting savings of approximately $52,000 USD/year from the reduction of scrap.
