If there is one message I would like to communicate, whatever your job title and however your work is touched by software development, it is this: software development is capable of much, much more than it is currently delivering. Defects should be notable because they are rare. Major scope adjustments because of lack of progress should only need to occur in the first half of schedules. Initial deployment of software should come after a small percentage of the project budget is spent. Teams should be able to grow and shrink without catastrophic consequences. XP is a way to get to that place. When we work with human nature in our development process, we have the opportunity to make these big leaps in effectiveness.
