This Phase I proposal responds to the Solicitation requirements by scoping the effort involved in developing a common software executive and aligned library of reusable support modules in parallel with a facilitating reuse infrastructure. Rather than focusing on libraries and other failed strategies, the contractor proposes to use the modern architectural concepts of service-oriented architectures, persistence and predictive computing to build a real-time executive for flight systems in a standards-based and platform-independent manner. The reuse infrastructure being built in parallel consists of a framework and related toolset that makes it easy for engineers to identify and retrieve reusable assets that provide proven value. The contractor will develop specifications for the common software executive and library of reusable support modules during Phase I. The infrastructure will be prototyped and used for a Phase I demonstration. A market survey will be conducted as part of the effort to scope the commercialization prospects and develop an initial business plan that will be used to interest potential pilot projects in partnering for a Phase II effort.
