If you read the introduction to this book, you already know what project management has to do with IT, but now we're going to break it down a bit further and look at how Information Technology (IT) projects benefit from project management and by extension, how your career will benefit from project management. In this chapter, we'll begin by looking briefly at business process improvement and how project management fits into that world. We'll also look at some of the brutal facts about project success (or rather, failure) rates as well as the factors that can have the most impact on project success. We'll close out the chapter by looking at project constraints and elements to give you a solid foundation for the subsequent chapters. Let's start by looking at business process improvement systems and where project management fits.
