About this eBook
It is indeed a great pleasure and proud privilege for me to present this treatise on Total Quality Management to the immediate benefit of final year engineering students of all branches. This book is written in tune with the latest syllabus of various universities and we have taken the syllabus as guidelines for the organization of this book. In writing this book, the author has constantly kept in mind the tremendous amount of ground which the student and the practicing engineers of today is expected to cover. No effort has been spared to enrich the book with simple language and self-explanatory diagrams. The author s responsibility here is to stress abundantly that we lay on no chaim to the original research in preparing this text. Many of the subject matters that are available in the works of eminent authors have been made freely. Perhaps, what we may chaim, in all modesty, is that we have tried to fashion the vast amount of materials available from primary and secondary sources into coherent body of description and analysis. I am very thankful to Dr. A. Shanmugasundram, Chancellor of Vinayaka Missions Unversity, Salem, Tamil Nadu. Dr. A. Nagappan, Principal, Prof. P. Ganasekaran, Dean, Placement, V.M.K.V. Engineering College, Periya Seeragapadi, Salem, Tamil Nadu.
