Planning the integration is focused on which implementation subsystems should be implemented, and the order in which the implementation subsystems should be integrated in the current iteration.

Integration is typically carried out by a single person (for a small project on which the build process in simple) or a small team (for a large project on which the build process is complex). The integrators need experience in software build management, configuration management, and experience in the programming language in which the components to be integrated are written. Because integration often involves a high degree of automation, expertise in operating system shell or scripting languages and tools like 'make' (on Unix) or 'ant' (for Java) is also essential.
