SWIM Engagement – Pre-Lifecycle • SWIM Monitors JRC Secretariat Watch Lists • SWIM Contacts BRIAN Team to set up SOA Suitability Analysis • Introduce SWIM Concepts and Capabilities • Learn about BRIAN Concept • Conduct Suitability Questionnaire • Does Capability already exist? • Can existing services be orchestrated to produce this capability? • Is it Reusable (i.e. multiple consumers)? • Score questionnaire (100 pt. scale)
Suitability Analysis and Coordination • Analysis shows High Value in SOA Solution • No overlap with existing systems • Multiple consumers • NAS Information Display Systems (IDS) • Food Concession Supply Chain Mgmt. (SCM) • SWIM prepares Memorandum of Analysis coordinated with BRIAN Team • Analysis briefed to Technical Review Board (TRB) • TRB Approves development of BRIAN capabilities as SOA Services

Service is Consumable • Facility IDS requests “Beverage Resource Query” Service via NSRR • Allow Status Requests from IDS console • SLO parameters: • Available 24 / 7 • Up to 3 queries per minute, 2 second response time • .999 Operational Availability • Mean Time to Repair (MTTR) 2 hours • BRIAN Team accepts Service Consumption request via NSRR • De facto SLA created with SLO parameters
Service Updates • BRIAN wants to add Tea Bag monitoring/reporting to Services • Change is Backward-Compatible, so classified as Minor • SWIM Version Management Process • Version 1.1.0 created in NSRR • Advance through Lifecycle • Task changes noted in NSRR, e.g. CCD instead of FID • v1.1.0 in Production, then v1.0.0 Deprecated
