Identify which other implementation subsystems are needed for this build. Decide which version of each subsystem to
use. Update import dependencies for this subsystem to the correct versions of the other subsystems.
If new system baselines have recently been promoted, the integrator will also have to decide when to update
(rebaseline) the subsystem integration workspace. This decision is based on where in the development cycle you are. If
your subsystem development is unstable in some critical area, then you may decide to postpone rebaselining.
When it is late in the project, and close to a release (whether internal or external), it is crucial that subsystems
have consistent import sets. Then there is a greater urgency to stay current with the system baselines.
