I've had several people tell me how useful the Scrum/XP cross-reference in our book is, so I thought I'd share it with you, too.

To create this chart, I referred to Ken Schwaber & Mike Beedle's Agile Software Development with Scrum and both editions of Kent Beck's Extreme Programming Explained. Practices that are similar are cross-referenced, but that doesn't mean they're identical. Refer back to the source material to understand how cross-referenced practices differ.

If a row lists n/a for a particular method, that means that there is no corresponding practice defined in that method. Implied means that a similar approach is included or assumed, but it's not described in detail.

If you have corrections, please let me know, with references when possible. I intend this to be a living document.
