Exploring the Science Trade Space with the JPL Innovation Foundry A-Team Special Issue Article Concurrent Engineering: Research and Applications Exploring the science trade space with 1–11 Ó The Author(s) 2017 Reprints and permissions: the JPL Innovation Foundry A-Team sagepub.co.uk/journalsPermissions.nav DOI: 10.1177/1063293X17740406 journals.sagepub.com/home/cer John K Ziemer, Randii R Wessen and Paul V Johnson Abstract The Jet Propulsion Laboratory Innovation Foundry has established a new approach for exploring, developing, and evalu- ating early concepts with a group called the Architecture Team. The Architecture Team combines innovative collabora- tive methods and facilitated sessions with subject matter experts and analysis tools to help mature mission concepts. Science, implementation, and programmatic elements are all considered during an A-Team study. In these studies, Concept Maturity Levels are used to group methods. These levels include idea generation and capture (Concept Maturity Level 1), initial feasibility assessment (Concept Maturity Level 2), and trade space exploration (Concept Maturity Level 3). Methods used for exploring the science objectives, feasibility, and scope will be described including the use of a new technique for understanding the most compelling science, called a Science Return Diagram. In the process of developing the Science Return Diagram, gradients in the science trade space are uncovered along with their implica- tions for implementation and mission architecture. Special attention is paid toward developing complete investigations, establishing a series of logical claims that lead to the natural selection of a measurement approach. Over 20 science- focused A-Team studies have used these techniques to help science teams refine their mission objectives, make imple- mentation decisions, and reveal the mission concept’s most compelling science. This article will describe the A-Team process for exploring the mission concept’s science trade space and the Science Return Diagram technique.

She was born in Chicago and enrolled at the University of Chicago when she was 14. Lynn was a renowned biologist and University Professor in the Department of Geosciences at the University of Massachusetts, whose faculty Margulis joined in 1988. Prior to that she taught at the University of Boston for 22 years. She is best known for her theory on the origin of eukaryotic organelles, and her contributions to the endosymbiotic theory. She is also associated with the Gaia hypothesis, based on an idea developed by the English environmental scientist James Lovelock. The author of Symbiotic Planet: A New Look at Evolution penned hundreds of research papers and many books during her illustrious career. She taught classes in environmental evolution for nearly 40 years. Lynn, who was once married to astronomer Carl Sagan and then to chemist Thomas Margulis, was elected to the National Academy of Arts and Sciences in 1983 and received the National Medal of Science in 1999. She is survived by her four children and nine grandchildren. For a full obituary see the New York Times News Service at : http://bendbulletin.com/apps/pbcs.dll/article?AID=/20111125/NEWS0107/111..
