This document discusses integrating risk and knowledge management practices at NASA's Exploration Systems Mission Directorate (ESMD). It outlines five practices ESMD has adopted: 1) establishing "Pause and Learn" processes to reflect on lessons; 2) generating and using "Knowledge-Based Risks" to convey lessons; 3) establishing "Communities of Practice" to share knowledge; 4) providing knowledge sharing forums; and 5) promoting experience-based training. The goal is for ESMD to effectively learn from the past and generate shared knowledge to help achieve the complex technical challenges of returning to the Moon and Mars.
