Slide 13 of 17
Notes:
Eight practices remain to be addressed beyond the minimal: Planning Game, Metaphor, Simple Design, Refactoring, Collective Ownership, 40-hour week, Open Workspace, and Coding Standards. The XP practice known as the Planning Game addresses aspects of the Project Planning Practice Area. The Metaphor, Simple Design, Coding Standards, and Refactoring practices cover aspects of the Technical Solution and Product Integration Process Areas. The Collective Ownership partially addresses aspects of the Configuration Management Process Area. The 40-hour workweek is an industry best practice that is not specifically addressed in the CMMI and therefore could be easily added to the minimal CMMI compliant XP process. Similarly the open workspace practice is outside of the scope of the CMMI. Paulk explains, "The values of XP should be captured in any modern software project, even if the implementation may differ radically in other environments. Communication and simplicity may be stated in other terns (coordination and elegance, for example), but without them non-trivial projects face almost insurmountable odds. The XP principles of communication and simplicity are fundamental process design principles for organizations using the Software CMM also."
