What is the function of models federated within an Authoritative Source of Truth? - Specialty models change regularly during system design, so their inputs are not federated into the Authoritative Source of Truth until after Critical Design Review. - The federated models provide input to the system model until the critical design review, after which they no longer change. - Various specialty models will span many disciplines, so they must be federated with the system model in order to provide a unified representation that enables concurrent engineering and other program activities. - System design changes are managed within the system functional model, so the federated models do not need to be updated or synchronized with the system functional model..

1. What is the function of models federated within an Authoritative Source of Truth?
- Specialty models change regularly during system design, so their inputs are not federated into
the Authoritative Source of Truth until after Critical Design Review.
- The federated models provide input to the system model until the critical design review, after
which they no longer change.
- Various specialty models will span many disciplines, so they must be federated with the system
model in order to provide a unified representation that enables concurrent engineering and other
program activities.
- System design changes are managed within the system functional model, so the federated
models do not need to be updated or synchronized with the system functional model.
