Main Description
|
Implementers deliver their tested Implementation Elements into an integration workspace, whereas integrators combine
them to produce a build. 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.

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
successful integration.

| 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.
