Mobile order provisioning flow orchestrated through Oracle SOA, AIA, and OSB middleware connecting Siebel order capture to downstream fulfillment systems. Orders flow from Siebel through the Oracle integration layer to Numeritrack, Viper, Surepay, INPROM, and Oracle BRM, with INPROM further routing to CUR, PEGA, and Surepay for provisioning execution. This architecture illustrates a common telecom OSS/BSS integration pattern but highlights critical gaps: limited error handling, no rollback mechanisms, and no automatic retries. Enterprise architects can fork this diagram on Diagrams.so to model resilience improvements like compensating transactions, circuit breakers, or event-driven retry logic. Ideal for documenting legacy telecom provisioning flows or planning modernization to microservices with robust error handling.
