Of course that problem is endemic to systems development in general but since XP proponents claim that the approach is superior then fewer instances of building the wrong system should be evidenced. As to research in this area while planning is critical and essential for success it remains to be seen as to whether the specific XP approach is more beneficial than other more standard approaches to developing user requirements. Companies or organizations using the heavier methodologies typically had trouble adopting incremental releases because of the implications that core practice has for several other core practices simple design testing refactoring and continuous integration. These core practices appear to be closely related since for example a daily build means that the testing suite must also be ready daily which in turn has implications for continuous integration and refactoring. Research into these core practices will nevertheless be necessary if the overall approach is to be accepted by the mainstream. If pair dynamic programming is used the coding-standards core practice means that developers must agree up front on the conventions used for naming classes as well as for example on a host of other coding practices. A coding standard in the end means that someone looking at a code segment cannot tell which team member wrote it. This should be something that programmers do for all projects but sadly it is not. Research should be implemented that compares practice with recommendation in both the traditional and XP areas. However this instance also highlights once again the difficulties of examining XP s core practices individually the likelihood that interaction or correlation between and among other core practices will be possible and even .
