Is This the Future of Acquisition?
In an environment where rapid change is a fact of life,
our current capability development paradigm is
inadequate. Large, complex programs with industrial-
era development cycles measured in decades may
become obsolete before they reach full-rate production.
The new disciplines required of our Air Force are that of
integrator and synchronizer – directing how and when
the elements must fit together.

Some Systems Engineering Philosophy
1964 2015Progress?
� Future acquisitions must be different, so let’s do systems engineering differently
� Architecture products should participate actively in verification of designs andimplementations

• Class groups related Functionality
• Container for Interface Ports
• Interface Port ‘provides’ (exposes) an Interface
• Defines ICD characteristics
• Interface defines Events
• Groups required pieces of data to make an Interface
• Event contains data element
• Represents a specific data format
• Statechart defines behavior when Interface is used• Represents the “service contract”

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

Step 1: Define Interfaces
“DataViz” port provides
“VisualizedItems” interface that specifies “OwnshipPosition” event
“OwnshipPosition” event specifies detailed data format as an argument
Class has “DataViz” port
Page 9
| 9 |
Step 2: Create Business Logic Simulation
“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!

Step 3: Analyze Model Execution

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
