IT Performance Management addresses the way organizations should balance the demand and the supply of information technology, optimizing the cost and maximizing the business value of IT.In this book several aspects of IT performance management are described. The way this management is executed and the techniques, which should be used, depend on the maturity of the relationship between the IT function and the lines of business of an organization. The foundation of the authors' approach is based on the flow of money and related management objectives. However, performance management is primarily based on perceptions. Therefore, this book introduces the IT value perception model. This model describes four separate levels of perception for the business value of IT. If the demand and the supply of IT do not share the same perception level, the balance is lost, which will lead to friction and inefficiency within an organization. This book is not about what is good or what is bad, but rather is about the 'what', the 'why' and to a limited extent the 'how' of managing the performance of IT. Therefore, the book finishes with a 'back-to-business' section in which a self-assessment checklist, a potential growth path and ten next steps are provided. This enables the reader to start applying this book in his every day working environment immediately.
