Mission Utility vs. Mission Performance: Redefining the End Goal of Space Mission Design in the Conceptual Phase

This paper explores the distinction between mission utility and mission performance in the conceptual design phase of space missions. While traditional approaches, such as the Space Mission Analysis and Design (SMAD) methodology, focus on optimizing mission performance metrics (e.g., payload capability, orbit selection, and system reliability), this paper argues for a paradigm shift toward mission utility as the primary end goal. Mission utility emphasizes the value delivered to stakeholders rather than just the technical performance of the system. By integrating concepts from the Generalized Information Network Analysis (GINA) methodology, this paper addresses a framework that redefines the end goal of space mission design to prioritize stakeholder satisfaction, cost-effectiveness, and adaptability over traditional performance metrics.
