Since communication is a critical aspect of XP, the people involved must know up front
what they can expect, and what is expected of them. As such, the following are lists of
"rights" that the Customer and Developers are accorded in XP:
Customer Bill of Rights
As the customer, you have the right to:
- An overall plan, to know what can be accomplished, when, and at what cost;
- Get the most possible value out of every programming week;
- See progress in a running system, proven to work by passing repeatable tests that you specify;
- Change your mind, to substitute functionality, and to change priorities without paying exorbitant costs;
- Be informed of schedule changes, in time to choose how to reduce scope to restore the original date, even cancel at any time and be left with a useful working system reflecting investment to date.
As the Developer, you have the right to:
- Know what is needed, with clear declarations of priority;
- Produce quality work at all times;
- Ask for and receive help from peers, superiors, and customers;
- Make and update your own estimates;
- Accept your responsibilities instead of having them assigned to you.
These rights resonated with me in 2001, and I believe we need to revisit them from time to time in order to ensure that the values of Agile are instilled within an organization.
