Objective

This project uses the WinWin system definition paradigm, the WinWin Spiral Model, and Internet-related software technology to develop distributed collaborative negotiation aids and interactive analysis tools for better and faster definition complex evolutionary software-intensive systems. It  uses Air Force satellite ground systems as its primary domain for domain exploitation, experimentation, and technology transition. The project also serves as integrator for DARPA-EDCS technology in the Rationale Capture cluster.



Approach

The project's model-driven approach integrates models of the domain (satellite ground system), life cycle process (WinWin Spiral Model), system definition products (MIL-STD-498 extended by prototypes, domain models, evolution specifications, and rationale capture), system definition satisfaction criteria (stakeholder win-win), architecture (DARPA ADL's and UML), and architecture-based attributes such as cost, schedule, performance, reliability, and interoperability (COCOMO® and associated parametric models; Architect's Automated Assistant (AAA)).

The project has four major tasks:

  1. Refining and extending the WinWin System and WinWin Spiral Model for more powerful rational capture and distributed collaboration support (USC lead).

  2. Architecture-based attribute analysis tools (USC and TRW lead)

  3. Experimental application to satellite ground systems (SGS), (Aerospace and TRW), including exploratory definition of consensus-based open SGS architectures (Aerospace lead).

  4. Exploratory exercise and integration of other EDCS technology in SGS domain (Aerospace and TRW).
