"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
