1. Customer (to team): "Here's a new story."

This means:

  • I (the customer) have a new requirement.

  • I'll write a few sentences on a card as a reminder for us.

  • I'm prepared to discuss this with you in more detail later.

  • I understand my requirement well enough that I could specify a test that would assure me the implementation is correct.

As you can see, a simple statement is more than a truth about the world; it's also a web of promises and understanding.

2. Programmer (to customer): "We estimate this story to be a 1 (or a 2 or a 3)."

This means:

  • We've based our estimate on what you've said, any tests you've shown us, any experiments we've done, and on our knowledge and experience.

  • The estimate is relative to other estimates we've made.

3. Programmer (to customer): "Could you split this story?"

This means:

  • We don't feel confident enough to make an estimate because the story is too big.

  • We know programmers don't always do so well at splitting stories in a way that maximizes value, and we know you'll be happier if you split it your way.

4. Programmer (to customer): "Our velocity is n points per iteration."

This means:

  • Without real experience, we'll give you our best guess or estimate.

  • We know you understand that the real velocity could be different from this estimate.

5. Programmer (to team): "Our pair is going to integrate."

This means:

  • Don't rely on the mainline code for a while, as it will be unstable while we change it.

  • We won't take too long.

  • If we can't integrate successfully, we'll put the mainline back the way it started.

6. Programmer (to team): "Is anybody integrating?"

This means:

  • We're seeing something funny; is someone in mid integration?

    or

  • It doesn't seem like we're integrating enough today.

  • Etc.

7. Programmer (to team): "We're done integrating."

This means:

  • It's safe to fetch the latest version again.

  • Unit tests are running at 100%.

  • Let us know if you have any questions about the things we changed.

8. Programmer (to team): "This task is done."

This means:

  • We believe that the code needed for the task is present and working properly.

  • We built tests for the code we added.

  • We refactored to make that code as clean as possible.

  • We're free to start another task, or help anybody who needs it.

9. Programmer (to customer or whole team): "We're done with this story."

This means:

  • All tasks for this story are complete.

  • Any customer-defined tests are implemented and working.

  • We'll show this feature to the customer and make sure they think it's done too.

10. Customer (to team): "This story is done."

This means:

  • This feature is working the way we expected.

  • Please move on to the next story.

  • If we want this to work differently in the future, we know it's a new feature to negotiate.
