Two of the principal challenges in efficient trade space exploration are (1) quickly evaluating options, and (2) quickly obtaining stakeholder understanding of the results of the evaluation. This presentation describes the processes & methodology that have led to a factor of nine improvement in the efficiency of trade space exploration of space systems in Team-X at the Jet Propulsion Laboratory. The principal method that has enabled this increase in efficiency is the separation of the exploration figures of merit into two distinct types, which are then addressed in an efficient order. The figures of merit in a trade space exploration of N subsystems either scale with the number of interactions between the subsystems and the external constraints, O(N), or with the number of interactions between subsystems, O(N2-N).
