Manage the data connectivity between Cameo System Modeler and IBM Rational DOORS
Work closely with requirements engineers to establish and maintain relationships and traceability between modeled architecture and authoritative system requirements
Work with interface engineering teams to ensure system interfaces, logical and physical connections, exchanges, and dependencies are consistently represented within the model
Work with verification and test organizations to incorporate verification methods, relationships, evidence, and system behavior into the modeling environment as appropriate
