2 Is This the Future of Acquisition? 2 In an environment where rapid change is a fact of life, our current capability development paradigm is inadequate. Large, complex programs with industrialera development cycles measured in decades may become obsolete before they reach full-rate production. ThenewdisciplinesrequiredofourAirForcearethatof integrator and synchronizer directing how and when the elements must fit together. -U.S. Air Force 30 Year Strategy 2015 The MITRE Corporation.

3 Owning the Technical Baseline is SAF/AQ Priority And It Makes Sense 3 Our View Unambiguous Technical Data Product more than Document Centric Used to Solve Problems Manage System Evolution 2015 The MITRE Corporation. Approved for Public Release; Distribution Unlimited. Case Number

4 Some Systems Engineering Philosophy Progress? Future acquisitions must be different, so let s do systems engineering differently Architecture products should participate actively in verification of designs and implementations 2015 The MITRE Corporation.

7 Model-Based Engineering 7 Model is the design Useful by broad community (war fighter, engineer, tester) Auto-generated documentation Executable Government Reference Architecture integrated in SIL

8 Step 1: Define Interfaces 8 Class has DataViz port DataViz port provides VisualizedItems interface that specifies OwnshipPosition event OwnshipPosition event specifies detailed data format as an argument

9 Step 2: Create Business Logic Simulation 9 Inside Class is the business logic simulation Run this code when an OwnshipPosition event is received Result: Display position on executable model s Globe display if message is formatted correctly!

10 Step 3: Analyze Model Execution 10 Executable GRA showing simulation of processing a OwnshipPosition message

16 16 Benefits Discover defects in the design earlier in the development cycle Bridge system and software engineering teams Improve efficiency and communication Consistent design/interface documentation Generate documents such as ICDs directly from model Improve design/review process during active development Base design reviews around model artifacts Decrease time to bring new engineers up to speed for development and support Easier technology insertion/upgrade impact analysis over project lifecycle Need to be committed to process and provide adequate resources to achieve benefits 2015 The MITRE Corporation.
