Payload Safety Working Group

“NASA ELV payload missions involve various combinations of payload organizations, payload contractors, launch vehicles, payload processing sites, and launch sites. To address this situation, a key aspect of the safety review process is the establishment of a unique PSWG [Payload Safety Working Group] for each payload.

“Each PSWG and its required activities are designed to ensure the appropriate involvement and coordination of all organizations and stakeholders that support the associated mission and share safety responsibility for the mission (internal and external to the Agency)."

Objective Hierarchy

Objectives Hierarchy

The Office of Safety and Mission Assurance (OSMA) has introduced a new objectives-based approach to better support NASA’s increasingly complex missions in a changing design environment. By focusing on objectives, OSMA hopes that the new standards will be more flexible, agile and cost-effective, and will allow more ingenuity to achieve objectives. It will serve as a guide to help programs and projects plan how they will meet their objectives, instead of dictating what they must do to via prescriptive requirements. Read the article, “OSMA Introduces New Objectives-Based Strategies,” to learn more about objective hierarchies.
