SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Systems engineers working on safety-critical aerospace programmes struggle to recall and apply the detailed guidance in NASA/SP-2014-612 when structuring safety cases, scoping analyses, or evaluating risk arguments mid-task. ## Core Features & Use Cases - RISC Development Guidance: Build risk-informed safety cases with claims trees, direct and supporting evidence, and 1-5 assurance deficit scoring. - ISA and Graded Analysis: Scope integrated safety analysis using Priority 1/2/3 rankings, safety performance margins, and SPF-derived requirements. - RISC Evaluation Support: Apply the three-phase staged evaluation (acceptance review, surveying, auditing) with deficit-importance matrices and VOI analysis. - Use Case: Ask how to set a probabilistic safety requirement for a new launch vehicle, and the skill reads chapter 4 to explain the safety threshold, safety performance factor, and burndown profile derivation. ## Quick Start Ask the skill how to structure a risk-informed safety case for a Priority 1 crewed mission, including claims tree and assurance deficit scoring.

Frequently Asked Questions about nasa-system-safety

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure a risk-informed safety case (RISC)?▼

Build a claims tree top-down from operational safety objectives: a top claim of adequate safety decomposes into intermediate and base claims. Each base claim needs direct quantitative evidence, supporting qualitative evidence, and a 1-5 assurance deficit score.

How much safety analysis depth does my NASA mission require?▼

Use the graded Priority ranking: Priority 1 (human spaceflight, over $1B, strategic) requires full PRA plus qualitative analysis; Priority 2 ($250M-$1B) uses qualitative analysis with targeted PRA; Priority 3 (under $250M) uses qualitative analysis only.

What is the difference between Acquirer and Provider safety roles?▼

The Acquirer performs safety assurance: setting requirements, evaluating the RISC, and accepting risk. The Provider performs safety ensurance: achieving adequate safety through design and building the RISC and SSMP. A Provider sub-tasking another organisation becomes the Acquirer for that relationship.

Does this skill cover nuclear or chemical safety standards?▼

No. The pack covers only NASA/SP-2014-612 Volume 2 content on system safety for aerospace programmes. It excludes nuclear and chemical safety domains, occupational health regulations, and NASA programmatic requirements unrelated to system safety.

How are assurance deficits scored and managed in a RISC?▼

Each base claim receives a 1-5 deficit score, from rank 1 (about 95-100% confidence) to rank 5 (about 0-35% confidence). Deficits rated 3 or higher convert into CRM risk statements with assigned owners tracked under NPR 8000.4A.
