Subsystem integration proceeds according to the Artifact: Integration Build Plan, in which the order of Implementation Element and implementation subsystem integration has
been planned. If a subsystem is large, a subsidiary Integration Build Plan may have been created specifically for the
It is recommended that you integrate the implemented classes (implementation elements) incrementally bottom-up in the
compilation-dependency hierarchy. At each increment you add one, or a few elements to the system.
If two or more implementers are working in parallel on the same subsystem, their work is integrated through a
subsystem integration workspace, into which the implementers deliver elements from their private development
workspaces, and from which the integrator will construct builds.
If a team of several individuals works in parallel on the same subsystem, it is important that the team members share
their results frequently, not waiting until late in the process to integrate the team's work.
