TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
Concept phase space-systems architecture evaluations typically use mass estimates as the primary means of ranking potential mission architectures. Software does not directly have physical mass and, as a result, is often left-out of such evaluations, despite the potential of being one of the main contributors to a mission's overall cost and risk. During NASA's Concept Exploration and Refinement (CE&R) program, personnel from MIT, Draper Laboratories, and Payload Systems Inc. developed a systems architecture software assessment approach that addresses both the early concept phases of a program and the complexities of critical embedded software systems. This approach uses a series of weighted software and human-computer interaction parameters that evaluate how a system's architecture affects software. Payload Systems Inc. proposes to validate this Systems Engineering Software Assessment Model for Exploration as the next step on the path to a tool that provides early, reliable ranking of systems architectures based on software.
The Phase I effort will focus on validation of this assessment tool. This validation will be based on embedded spaceflight systems projects. Once validated, this assessment approach will provide a basis, during Phase II, for the development of a Systems Engineering tool for assessing the impact candidate system architectures on software.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
This systems engineering software assessment was specifically aimed at elements of NASA's Exploration Initiative, where early decisions in systems development have a significant impact on the overall software development, maintenance, and human-computer interaction cost and risk. Additionally, this model is applicable for any number of NASA programs that require embedded software development, such as Constellation-X, the James Webb Space Telescope, and the Laser Interferometer Space Antenna.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
This systems engineering software assessment model is applicable to DoD and commercial projects that require modeling and assessments of embedded software development cost and risk and human-computer interaction costs and risks. These include aircraft avionics systems, medical instrumentation systems, optical communications monitoring systems, etc.
