With xp programming for example, you need the users participation during the process of development as we develop with short iterations where the working software is always tested by the user. Requirements are always changing, even after the system has been put into its operating environment. The configuration management plan defines the process, which is used for making changes to the project scope. With the incremental model, the system is analysed, designed, developed, and tested in increments which are clearly.
