Throughout this book we refer to business projects. This term includes all the typical elements of business process redesign and development, new policy development, IT development, and change management. Readers who have either a business or IT background will find the concepts and techniques relevant. After all, there is no such thing as an IT project. eXtreme projects embrace and include all aspects of business, IT, policy, administration, human resources, change, and research effort that all projects should include. We also do not use the term user , which we dislike intensely, to refer to non-technical people. As we explain in the next chapter, this term has been used to marginalize and diminish the critical role that business experts and clients play in contemporary projects.
