This document discusses increasing the robustness of flight project concepts. It proposes several improvements and innovations, including establishing new concept maturity levels (CML) to better communicate a concept's readiness. A new P4 document is suggested to provide requirements and guidelines for incorporating and evaluating a concept's robustness. Additional proposed enhancements involve new tools and templates, increased project team support, organizational changes, and training for the pre-phase A community. The overall goal is to address current challenges around assessing risks, communicating maturity, and guidelines for robustness evaluations in NASA's competitive funding environment.
