Mission Success Starts With Safety 9 19 March ‘03 Safety: How does it fit in our priorities? First Shuttle program priority: Fly Safely Note: Safety is not the first priority! If it were, we would just stop flying and avoid all risk SLEP means doing what it takes to fly (safely) through 2020 Therefore, Supportability and safety share first priority

Mission Success Starts With Safety March ‘03 Safety: What does NASA mean? Objectives (in rank order): – Protect the public – Protect astronauts and pilots – Protect our workforce – Protect our high value equipment and facilities Core Elements: – Management commitment – Employee involvement – Hazard analysis – Risk mitigation – Training and education Strategic Plan Safety is a core value (not a mission) Think of it as an adverb that modifies all Agency verbs Agency Safety Initiative 1999

Mission Success Starts With Safety March ‘03 Safety: What about maintaining vs. improving? Maintaining safety is not good enough – Today’s safety level (even after fixing Columbia problems) is only appropriate for a going out of business schedule Unknown unknowns must be balanced by known unknown mitigators or they will slowly increase overall risk We must also figure out ways to limit the number of unknown unknowns Overall risk level is too high for a long term commitment (O’Connor philosophy issue) Extending shuttle through 2020 demands that we improve safety, not just maintain it Real world says that safety improvement upgrades will be limited by resources available… Suggestion: do not let mission changes compete for SLEP resources…demand that new missions bring money

Mission Success Starts With Safety March ‘03 Safety perspective on SLEP priorities 1.Fly to 2020 and maintain overall safety at current level (this means some improvements required to counter unknown risk creep) 2.Improve safety with ASI priorities in mind 1. Public 2. Our people 3. Our high value equipment and facilities 3.Meet the manifest (schedule dependability and current mission success improvements 4.Improve the system (efficiencies, and everything else that does not fall under 1-3) Note: new missions bring money
