Extreme Programming in Perl Robert Nagler phần 3 pptx

StoryTag This is a mixed-case identifier for the story. Giving a handle

to the story simplifies communication about it. In my experience,

customers tend to have trouble filling in this field in the beginning.

Programmers are used to naming things (subroutines, modules, etc.),

and they may be able to help the customer choose appropriate story

tags.

Release The date or name of the release. We use this field loosely to

categorize stories by release or project. We couldn’t predict when

CloseChase would be done, so we just put it in the Misc category.

Some teams work on several projects simultaneously, and this field

helps keep the story cards organized.

Priority After the customer physically orders the story cards, she writes

their numeric priority in this field. The numbering scheme is arbitrary.

Sometimes you need to insert a story card in the middle of a sequence.

We add a letter, for example, 5a, or use a dotted decimal notation,

5.1. If you drop the story cards, it’s important to be able to get them

back in priority order.

Author The person who wrote the story. You then know whom to ask for

the details.

on The date the story was written.

Accepted The date the story’s implementation is accepted by the cus￾tomer. We do this at the start of every planning game before we get

into the new stories. This helps remind the customer what has just

been accomplished, and, sometimes, lets the customer catch incom￾plete stories.

Description A few sentences and/or pictures explaining the requirement.

Be brief. If the description isn’t clear, rip up the card and start over.

This is the most important field, so you may want to fill it in first. See

examples in Stories.

Estimate The programmers write their best guess for the implementation

time. See discussion about the time scale in Estimation.

Considerations The programmers list the implementation risks and pre￾requisites in this section. This gives the customer more information

about the confidence of the estimate and helps her order dependent
