Jidoka in the Digital Age: How Toyota's Principle of Building Quality Evolves with AI, Industry 4.0, and Resilient Systems

Jidoka-Toyota's principle of "automation with a human touch"-is one of the two pillars of the Toyota Production System. While Just-in-Time has been widely adopted, Jidoka has often remained misunderstood, underutilized, or oversimplified. This book brings Jidoka to life for today's world of Industry 4.0, smart factories, and digital transformation.

In this expanded and updated second edition, Mohammed Hamed Ahmed Soliman revisits his original 2020 work and integrates the latest advances that are reshaping quality management: artificial intelligence, machine vision, predictive maintenance, and digital twins. The result is a practical, modern guide to building defect-free processes that withstand the challenges of complexity, disruption, and global competition.

What you'll learn in this edition:

• The two concepts of Jidoka: separating man from machine, and building quality into the process.
• How Toyota balances productivity and quality using andon systems, buffers, and culture.
• Modern applications of Jidoka with AI, IoT, and Industry 4.0.
• Case studies from healthcare, logistics, services, and digital industries.
• How to apply tools like FMEA, root cause analysis, and A3 problem-solving in today's digital environment.
• Lessons from Toyota's recalls and the rising cost of quality in the EV and software-driven era.

Why this book?

• Practical: Clear frameworks, checklists, and tools you can apply immediately.
• Modern: Updated for 2025 realities-AI, smart factories, and global supply chains.
• Universal: Examples across industries, from manufacturing to healthcare to software.

Whether you are a Lean practitioner, engineer, quality professional, or business leader, this book will help you understand Jidoka in depth and apply it to create resilient, defect-free systems in the digital age.
