"There are many books about topics and disciplines in Information Technology. But most books concentrate on a single area. This book is an exception - it looks at three disciplines and ties them together. Excellent idea. Congratulations to Koray for putting this book together, and also for his generosity in donating profits to schools."
-- Dorothy Graham, Best-selling Author

"Koray does a great job of using clever, insightful metaphors to illustrate concepts. He writes in an accessible, easy-to-read style. I hope you enjoy reading this book as much as I did."
-- Rex Black, Best-selling Author

"In his book Koray uses two phrases again and again. The first is "Quality is not tested, but built." The other phrase is "... should first be handled as a people issue rather than a technology issue." To those in the IT world who need an understanding of these principles, I recommend this book."
-- Lee Copeland, Best-selling Author
