It's just an abstraction. Climate scientists know how to deal with their climate system, but they may not be equipped to then relate their data back to a military defense system or water treatment plant. SoS allows a different team to take a set of not-quite-related systems and analyze their interactions, similar to how a climate scientist might analyze climate models.
