Since the late 80s, the Japanese techniques of Kaizen have helped businesses across the world to retain their edge. These techniques still work in the current business environment, which require employees to respond quickly to directives from the top management. The 12 in-depth case studies in this book take a step-bystep approach, documenting the ‘Best Practices’ of Quality Control Circles in top-performing companies that applied updated Kaizen principles, to achieve these very aims. This book is the direct result of an ambitious research and documentation exercise by Japan’s QC Circle Kanto Branch to map the most recent developments around the application of Kaizen techniques in top-performing companies in both the service and manufacturing sectors in Kanto, Japan. The results of their research brings together, for the first time, in-depth, first-hand accounts of Japanese QC circles working on solutions to complex problems and challenges in manufacturing companies like Nissan Shatai and Kose Cosmetics and in service sector businesses like a hospital, call centre and a packaging and shipping company. It serves as a practical and easy-to-understand manual for those who would like to replicate these recent Kaizen ‘Best Practices’ in their own businesses. These illustrative case studies are accompanied by flow-charts, diagrams, tables, and also “key take-aways”, to help the reader better absorb the ‘Best Practices’ at play in order to replicate them. Give your company the ‘new and improved’ Kaizen advantage by embracing the practical wisdom of these revolutionary, award-winning QC circles.
