Seven Methods and Three Elements of Quality Control in Manufacturing

A comprehensive explanation of the 7 major methods and 3 elements of quality management. A practical guide for optimizing QCD on-site using the 7 QC tools, PDCA, and 5S!

This document is a helpful resource for quality control (QC) in the manufacturing industry. It breaks down quality management into three elements: "process management," "quality verification," and "quality improvement," explaining the specific initiatives and importance of each. Furthermore, it introduces the essential "7 QC tools" for quality improvement, as well as the "new 7 QC tools" for handling language data, along with seven major methods such as the PDCA cycle, 5S activities, 4M/5M management, IE, and TQC/TQM. It also explains how to select and combine methods according to the nature and objectives of the challenges, as well as organizational points for achieving continuous quality improvement. Quality management is a management foundation directly linked to a company's credibility and survival, contributing to cost reduction and adherence to delivery deadlines (optimization of QCD). In the latter part of the document, it presents case studies of the production management system FUSE for small and medium-sized manufacturers, demonstrating how it addresses on-site challenges such as centralized data management, elimination of dependency on individuals, and technology transfer, achieving a 100% continuous usage rate. We encourage on-site leaders and personnel to utilize this resource to realize high-quality manufacturing and sustainable corporate growth.
