The Air Force Lifecycle Management Center Simulators Program Office (AFLCMC/WNS) is creating an integrated and maintainable enterprise Model Based Systems Engineering (MBSE) system model for the current simulator enterprise baseline. This system model is essential to fulfilling the Operation Training Infrastructure 2035 Flight Plan and placing the Air Force simulator enterprise on the digital engineering path. The Operational Training Infrastructure (OTI) Enterprise System Model (ESM) contains data for each simulator to the subsystem level, including specifications, interfaces, data flows, and software versions. This system model will transform simulator acquisition into a digital engineering environment informing Request for Proposals (RFPs), Configuration Control Boards (CCBs), engineering design reviews, and verifying Engineering Change Proposals (ECPs). The system model will become a central hub for Government and industry to comprehensively control each Air Force simulator’s baseline with requirements, testing, reporting, and simulator architecture all in one easy to navigate model.  The OTI ESM will fundamentally change the communication between Government and Industry through the seamless delivery of simulator data through each system model, enhancing acquisition cognition. The OV-1 High Level Operational Concept Graphic below illustrates the scope of the OTI ESM.
