Application of 8D methodology: An approach to reduce failures in automotive industry

Abstract

The policy of quality enhancement in the production process within the entire has a critical role. This study was focused on quality management as a case study in the automotive industry using 8D methodology. Thus, it was considered as a quality process where 8D problem-solving occurrences were not for a failure item, but all chronic problems. The originality of the study eliminates active and recurring failures by using the 8D methodology. In addition, this is an original study that provides an analysis of existing technologies as Value Stream Mapping (VSM) and Failure Mode Effect Analysis (FMEA) within the 8D concept in terms of offering a new model and proposing an effective methodology. The purpose of this study is to minimize quality failures and increase the efficiency of the method within the framework of lean production by using the 8D methodology, which includes quality techniques such as Failure Mode Effect Analysis (FMEA) in the automotive industry. As a result of this study, it was determined that by applying the 8D methodology, the total parts per million (ppm) was reduced to about 0.00 from 1,071 and this improvement resulted in savings. It can be claimed that 8D can be used as a quality management method in process improvement.
