Engineering Quality Assurance From Fundamentals to Industrial Excellence

Everyone uses the word "quality."
Almost no one defines it the same way.

To a customer, quality means a product that simply works. To a regulator, it means conformance to a published requirement. To an accountant, it means avoided cost. To an engineer, it should mean something more precise and more demanding: the disciplined, evidence-based practice of building things that meet their requirements every time — by design, rather than by luck.

This book treats quality assurance not as paperwork bolted onto a finished product, but as an engineering discipline in its own right — with its own theory, mathematics, standards, tools, and professional pathways.

The through-line is simple and powerful: inspection finds defects; only prevention removes their cause. The cheapest defect is the one that never happens — and this book shows you, with real numbers, why prevention always pays.

Who this book is for

It's written for three readers at once: the university student meeting the subject formally for the first time; the practising engineer who inherited a quality system they were never taught; and the professional preparing for certification — CQE, Six Sigma, ISO 9001 auditor — who wants the reasoning behind the clauses, not just the clauses. You don't need prior training in statistics or standards. Each chapter meets you where you are and builds from there.

What's inside

Across 22 chapters and 226 pages, organised into six parts that move from first principles to industrial application:

• The meaning of quality, the gurus, and the four pillars — Deming, Juran, Crosby, Ishikawa, Taguchi, Feigenbaum, and the cost-of-quality model
• ISO 9001 and the sector standards — AS9100, IATF 16949, ISO 13485, and the process approach
• Metrology, calibration, gauge R&R, and measurement system analysis
• Statistical process control, capability, design of experiments, and acceptance sampling
• Root-cause analysis, CAPA, FMEA, fault trees, Lean, 5S, and Six Sigma DMAIC
• Reliability and risk, Industry 4.0, IIoT, AI, digital twins, and the certification pathway

Every chapter follows the same rhythm — objectives, theory and the mathematics behind it, the international standards that govern practice, worked industrial examples, a case study, and a generous bank of four-tier review questions, labs, projects, interview questions, and certification practice. A single, self-contained pathway from beginner to capable practitioner.
