Abstract: Tradespace exploration (TSE) supports the systems engineering technical management process of decision analysis by identifying compromises, revealing opportunities, and communicating the impacts of decisions across a systems development life cycle. TSE for Engineered Resilient Systems is envisioned to coalesce pertinent information tuned to specific decision makers, at the appropriate time, presenting a holistic view of decision impacts on required system capabilities. A "best common practice" process for establishing, managing, and exploring tradespaces is assembled. Several TSE tools are assessed against process steps and tool attributes. This study reveals that having a valid set of attributes and an understanding of how a cross section of tools can satisfy them is insufficient—what is needed is a deeper understanding of how these tools are used and, more importantly, how they can be used when performing TSE in support of the decision analysis process. Gaining this understanding will enable users to better assess if they possess the appropriate tradespace exploration tools.
