Abstract
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.
