STATISTICAL PROCESS CONTROL TOOLS FOR QC

This work presents a case study on the application of quality tools to improve product quality. One component was selected as object study because it presented higher percentage of nonconformities and was increasing over time. Before mass production, in pre-production, Statistical Process Control (SPC). It was performed, and it was concluded that the process was capable. No further SPC was done during production. After defective units were detected at increasing levels, it was apparent that process variability had increased and the process was no longer capable. The study ends with the development process improvement activities. In order to endure in an aggressive market, getting better quality and production of product or process is a must for any industry. SPC is an efficient controlling methodology for analysing, monitoring, managing, and recuperating process performance.The biggest benefits for implementing SPC in industries are enhanced Quality and Condensed Process Variation.
