The installation of the visual aids screen in the assembly process improved the detection and prevention of operating errors, reducing the percentage of scrap generated during production.
Before the improvement, the process contained 1.5% scrap; after implementation, the rejection rate was reduced to 0.5%, resulting in a total reduction of 1.0% in defective parts.
Considering an annual production volume of 299,520 parts, with a unit value of $3.77 USD, this reduction is equivalent to 2,995 recovered parts per year, representing an estimated annual savings of $11,292 USD in scrap reduction alone.
