System Engineering Challenges/Solutions for Software Development at the Army's Software Engineering Directorate (SED)

Problems can be addressed by:
1. Eliminating design/decomposition error propagation by fully testing and vetting system design requirements in their operational context at EVERY level of
requirements analysis and design synthesis USING A FULLY FUNCTIONAL SYSTEM AND OPERATIONAL ENVIRONMENT SIMULATION – THE SYSTEM MODEL
2. Fully parallelizing project development activities by performing design trade analyses in parallel with the design synthesis (decomposition) activities at every level using THE SYSTEM MODEL instead of costly physical prototypes.
3. Vetting “black box” requirements BEFORE beginning decomposition to “white box” elements by testing within THE SYSTEM MODEL, which represents the combined behavior of the “white box” elements within THE SYSTEM ENVIRONMENT MODEL
4. Using a modeling tool to generate THE SYSTEM MODEL that contains automatic code generation capabilities, so that as the model is verified at each design iteration the software source can be given to supporting specialty teams assessing certification. Code generation rules can be modified to meet required standards for security (EAL-4, EAL-6, DO-178, etc)
5. Developing the integration and test infrastructure and verifying its operation by concurrently developing THE SYSTEM OPERATIONAL ENVIRONMENT MODEL with THE SYSTEM MODEL of the system under development.
