Programmers provide estimates
and suggestions, which are blended with customer priorities in a process called the planning game.
Together, the team strives to create small, frequent releases that maximize value.
The planning effort is most intense during the first few weeks of the project. During the remainder of
the project, customers continue to review and improve the vision and the release plan to account for
new opportunities and unexpected events.
In addition to the overall release plan, the team creates a detailed plan for the upcoming week at the
beginning of each iteration. The team touches base every day in a brief stand-up meeting, and its
informative workspace keeps everyone informed about the project status.
Analysis
Rather than using an upfront analysis phase to define requirements, on-site customers sit with the team
full-time. On-site customers may or may not be real customers depending on the type of project, but
they are the people best qualified to determine what the software should do.
On-site customers are responsible for figuring out the requirements for the software. To do so, they use
their own knowledge as customers combined with traditional requirements-gathering techniques.
