                                           Dynamic management of  flows and attributes in the network architecture  Network analyzed to extract flows of system service uses




















                              Development of New Systems  (Refinement of Flows)  Flows refined into architecture traces of system services with attribute capabilities  Flows abstracted as architecture traces of system  service dependencies  Analysis of Existing Systems  (Abstraction of Flows)






















                       Systems Engineering with FSQ  defined with survivability  and other attributes
