An experienced Banking-CIO reveals the world of Information Technology in a company. There's a Grand-Canyon-sized gap between the expectations of computer users and what an IT department can effectively do. And this gap creates many victims-on both sides! This book is a one-of-a-kind bridge-builder for computer users to understand IT and to be able to talk to IT experts. It is deliberately written in layman's language and avoids IT-specific technical terms. Why do IT projects fail or always take longer than expected? Why is software so unstable? What do IT experts do all day, and why are there so many? What about IT security? This book is a translation of the second edition of the bestselling German book "Eine Million oder ein Jahr".
