Book

This book redefines quality engineering as a comprehensive intellectual framework for value-driven design, rather than a mere collection of statistical tools. Drawing on extensive hands-on experience in product development, the author presents quality engineering as a system that enables engineers to visualize, structure, and share design thinking throughout the entire product lifecycle. Starting from fundamental questions—“What defines a good product?” and “How can it be realized efficiently?”—the book establishes quality engineering as a strategic design discipline. It then develops a structured methodology featuring tools such as QFD, FMEA, fishbone diagrams, DoE, and the Taguchi Method, while also exploring their integration with digital technologies like AI, digital twins, and big data. Rather than functioning as a tool catalog, the book highlights the rationale behind method selection, offering rich visualizations and real-world examples. It empowers readers to apply these techniques strategically, improving decision quality and design robustness. Finally, the scope expands beyond manufacturing to include service industries, global supply chains, and UX/UI design—showing how quality engineering continues to evolve as a core capability for innovation and customer value creation.
