What People are Saying About This

From the Publisher

"This book is quite different from traditional books written on reliability engineering so far and is authored by a person who has a rich industrial experience of working with Ford Motor Company. The book is quite informative and provides a good insight of methodologies and techniques used in reliability engineering. This will go a long way in creating competitive products that perform well in the market and also provide customer satisfaction." (International Journal of Performability Engineering; 1/09)

"It is a very practical book which provides a comprehensive discussion on reliability engineering concepts and techniques throughout a product life cycle. The author has done a great job in explaining the up-to-date reliability techniques in a very practical manner and using simple and straightforward language. This book will prove very useful for reliability engineers, testing engineers, quality engineers and design engineers." (Reliability Review, December 2008)

"This book gives both starting and experienced engineers a very nice overview of the different methods and tools that can be used for reliability engineering. It is very nice that the book gives a lot of (often simplified) examples; it will therefore not be difficult to apply the theory in industrial practice." (Quality and Reliability Engineering International, 2008)

" This is a useful and an important book. It should be on the shelf of all reliability engineers and other engineers who have responsibility for product reliability. It will also be of interest to many of those doing research in the area. Overall, the book is well-written and easy to read." (Journal of Quality Technology, April 2008)

"The author has done a great job in explaining the practical and state-of-the-art techniques to access and enhance reliability throughout the product life cycle. This book deliberates on a wide range of topics in reliability engineering. Practical examples and exercises, mostly from the automotive industry, are used to illustrate the ideas and methodologies. Readers of this book are expected to have some knowledge of basic statistical inference, statistical modeling, and probability theory. This book will be of practical use for a variety of engineers, including reliability engineers, quality engineers, test engineers, systems engineers, or design engineers, who are working in different stages of the product life cycle. It will also serve well as a textbook or a reference book to students in a course on reliability, quality, or industrial engineering." (Technometrics, February 2008)
