  13. In warfighting, software has become the soul of our weapons. The DoD and our sons’ and daughters’ lives depend on Software Intensive Systems • Software challenges: • System complexity • Greater dependency • Huge legacy backlog • Growing investment in development and sustainment (but not S&T)

  14. S&T Challenge: Match the Solutions to the Problems Major DoD software problems are in software processes, tools and management • Need better S&T base in these areas • Especially with new evolutionary acquisition processes Current DoD software S&T investments are skewed toward product S&T • Although more is needed in software product S&T also DoD requires a balanced software S&T program addressing all its needs • Including expedited technology transition OSD-SIS looking for Summit to provide innovative need-oriented ideas • With strong benefit rationale

  15. Some of these needs Fielding complex critical functionality with software that has controlled and managed: • Safety • Reliability • Interoperability • Correctness • Maintainability • Cost and Schedule • Predictability • High Performance • Security Bringing software development cycles in line with hardware (and with the industrial market) • Better designs and architectures • Faster development • Fewer defects • Programmable H/W (FPGAs) – Multifunction • Multi-process synchronization Flexible, interoperable software systems • Self-adapting and self-aware • Extensible • Secure • Separable • Distributed

  16. Some of these needs - 2 New languages, methods, tools and compilers • Support Component concepts • Extend the Ada engineering concepts • Provide for higher levels of abstraction • E-Technologies • Object Oriented • Network Centric • Integrating autonomous systems New ways of defining requirements and designs • Executable • Evolutionary • Model-based • Provable • Interoperable, system-of-systems • Traceable • Risk-driven New ways of testing, fault identification and isolation • Model-based testing • Self testing, self correcting code • Testing large systems • Testing interoperability • Balanced analysis-review-test strategies

  17. COTS Challenges COTS integration principles, methods and tools • Synchronizing system and COTS vendor upgrade cycles • Tools and testbeds supporting COTS and equipment upgrades, and analysis of conflict between and among separate COTS products and government software • Domain compatibility analysis • Estimating, planning and documentation aids • COTS wrappers, connectors and other architectural approaches • Empirical analysis of COTS-based systems Architecture and negotiation techniques for COTS functionality changes, as they are under the control of the vendor, not the government Tools needed to ascertain reliability, safety and security of COTS products • Security (including origin risk and potential for Trojan Horse or other malicious code)

  18. Some ideas Expand and combine existing technologies • CMMI SW SE (product development improvement, not individual discipline improvement) • Merge System Engineering and software engineering technologies Methods for hurdling political and process barriers • Product lines • Evolutionary Acquisition • Multiple contractors • Competition without excessive information hiding Determine and use “jointness in development” success factors • Common components • Common architectures Experimentation – Demonstrate the efficacy of technologies • Design of Experiments (DOE) • Measurement/Analysis techniques Transition • Mixed DoD track record of transitioning tools (COBOL, IDEF, ARPAnet, OO tools, STARS, Ada, requirements languages) • Demonstrate system success base as dramatically improved Value, Reliability and Maintainability- Not just Performance, Cost and Schedule Knowledge • Better ways to reuse knowledge about software process (CeBASE Experience Factory)

  19. Challenge to Summit Participants The DoD community is making progress in employing current best software practices • SW-CMM and CMMI practices • Independent Expert Program Reviews • Practical Software and Systems Measurement • Architecture-based approaches Further progress depends on finding solutions to new DoD software challenges • COTS, evolutionary acquisition, legacy systems, massive distribution, agent coordination, mobility, rapid change, talent shortage, systems of systems We need your help in providing innovative DoD-need-oriented ideas • with strong benefit rationale
