Throughout this book, I??™ve scattered advice such as: ???If you can??™t demonstrate progress weekly, it??™s a
clear sign that your project is in trouble. Slow down for a week and figure out what??™s going wrong. Ask
your mentor for help.???
When I tell you to ask your mentor for help, I mean that the correct solution depends on the details of
your situation. Your mentor can help you troubleshoot the problem and offer situation-specific advice.

CHAPTER 3
Understanding XP
???Welcome to the team, Pat,??? said Kim, smiling at the recent graduate. ???Let me show you around. As I
said during the interview, we??™re an XP shop. You may find that things are a little different here than
you learned in school.???
???I??™m eager to get started,??? said Pat. ???I took a software engineering course in school, and they taught us
about the software development lifecycle. That made a lot of sense. There was a bit about XP, but it
sounded like it was mostly about working in pairs and writing tests first. Is that right????
???Not exactly,??? said Kim. ???We do use pair programming, and we do write tests first, but there??™s much
more to XP than that. Why don??™t you ask me some questions? I??™ll explain how XP is different than what
you learned.
