An iteration
planning meeting is called at the beginning of each
iteration to produce that
iteration's plan of programming tasks. Each iteration is 1 to 3 weeks
long.
User stories
are chosen for this iteration by the customer from the
release plan in order of the
most valuable to the customer first. Failed
acceptance tests to be
fixed are also selected. The customer selects user stories with
estimates that total up to the
project
velocity from the last iteration.
The
user stories and failed tests are broken down into the programming
tasks that will support them. Tasks are written down on index cards
like user stories. While user stories are in the customer's language,
tasks are in the developer's language. Duplicate tasks can be removed.
These task cards will be the detailed plan for the iteration.
Developers
sign up to do the tasks and then estimate how long their own tasks will
take to complete. It is important for the developer who accepts a task
to also be the one who estimates how long it will take to finish.
People are not interchangeable and the person who is going to do the
task must estimate how long it will take.
Each
task should be estimated as 1, 2, or
