An integrator is also responsible for planning the integration, which takes place at the subsystem and system levels, with each having a separate integration workspace. Tested elements are delivered from an implementer's private development workspace into a subsystem integration workspace, whereas integrated implementation subsystems are delivered from the subsystem integration workspace into the system integration workspace.  Related Information This section provides links to additional information related to this role. Concept: Development and Integration Workspaces Concept: Software Integration   Staffing Skills The appropriate skills and knowledge for this role include: knowledge of the system or part of the system to be integrated. In particular, the integrator needs to know the interdependencies between Implementation Elements and the inter-dependencies between Implementation Subsystems, and how their development and dependencies are expected to change over time. familiarity with integration tools Integrators need to have good coordination skills, as he/she often works with multiple developers to ensure a sucessful integration. Role assignment approaches It may sometimes be appropriate for an individual acting as an integrator to also act as tester. For example, if the project is small or the integration is at the subsystem level, it may be an effective use of resources to have the integrator and tester be the same team member. Indeed, for subsystem-level integration and test, a single individual might play the role of implementer, integrator, and tester. At the system level, however, we recommend that integration and testing are performed by an independent team.
