'With this book, Hasan Akpolat has recognized the increasing importance of services in national and global economies. He has demonstrated the applicability of what is seen as a traditional manufacturing concept - Six Sigma, in a service environment. In a clear and simple way, the book explores the key questions of "what six sigma is" and "how it can be implemented" in service environments. With a good balance of theory and case studies, this book would be an invaluable guide for operations managers in service environments, students and researchers of operations management.' Dr Adegoke Oke, Fellow in Innovation and Operations Management, Cranfield School of Management, Cranfield, UK 'With his book Six Sigma in Transactional and Service Environments, Dr Akpolat has produced an excellent practical guide for the Six Sigma applications. It provides great insight to the Six Sigma concept and focuses on the critical issues surrounding its implementation rather than simply listing its numerous statistical tools. Although, the emphasis has been put on the transactional and service processes, it can be easily used as a guide for the manufacturing processes as well. Overall, Six Sigma in Transactional and Service Environments provides an excellent mix of theory and practical examples without requiring a statistical degree from the reader to understand its content.' Gary Helou, Chief Executive Officer, SunRice, Australia. '...this book is an original analysis of the much-discussed quality tool.' Quality World, December 2004o
