There are a few practices in standard XP that I??™ve rarely seen in use and don??™t practice myself (Table 3-4). I??™ve
removed them from this book.
Table 3-4. Practices not in this book
Removed practice Reason
Metaphor Replaced with Ubiquitous Language
Shrinking Teams No personal experience; not essential
Negotiated Scope Contract Minimal personal experience; not essential
Pay-Per-Use No personal experience; not essential
Table 3-5 below shows how the practices in this book correspond to Beck??™s XP practices. I??™ve also included a
column for Scrum, another popular agile method.
Key: n/a: This practice is not part of the method, although some teams may add it. implied: Although this idea
isn??™t a practice in the method, its presence is assumed or described in another way.
