| description | Knowledge base from NASA-STD-7009B (Standard for Models and Simulations) with implementation depth from NASA-HDBK-7009B. Use for M&S criticality and programmatics, development evidence and capability assessment, verification/validation domains, uncertainty and sensitivity, use-phase results assessment, risk-informed decision reporting, and handbook life-cycle products. Covers STD-7009B (2024-03-05) + HDBK-7009B (2026-02-03) synthesized notes only; does not replace program-specific TA direction, NPR 7150.2 software requirements detail, or full PRA methodology. |
NASA Standard for Models and Simulations (7009B + Handbook)
Source: NASA-STD-7009B (2024-03-05) with NASA-HDBK-7009B (2026-02-03) (US Government work, public domain) | Chapters: 7
When to use
Reach for this pack when establishing or reviewing credibility of models and simulations that inform NASA (or NASA-like) critical decisions — criticality/intended use, M&S life-cycle planning, development pedigree and permissible uses, V&V domains, uncertainty/sensitivity, use-phase appropriateness, results assessment, and decision-maker reporting with mandatory warnings and risk acceptance.
Prerequisites: none — plain Markdown; no MCP server, API key, or licence tier needed at runtime.
How to Use This Skill
- Without arguments — load the core frameworks below.
- With a topic — ask about criticality, capability assessment, V&V domains, uncertainty, permissible use, results reporting, or handbook phases.
- With a chapter — ask for
ch01 through ch07.
Supporting files: glossary.md, patterns.md, cheatsheet.md.
Core Frameworks & Mental Models
Two-document stack
- STD-7009B: Mandatory M&S requirements (shalls) across programmatics, development, and use/reporting.
- HDBK-7009B: Implementation handbook — life-cycle phases, compliance interpretation, model/AI pedigree context, PM/Technical Authority roles.
Three-phase requirement spine
- Programmatics — intended use, criticality, plan, metrics, acceptance criteria, reviews, defects.
- Development — RWS/pedigree, CM of data/software, units, assumptions, math, limits, permissible uses, capability assessment, guidance; plus V&V and development uncertainty.
- Use and reporting — proposed use, appropriateness, inputs, setup, envelope control, messages, results assessment, risk, decision reporting.
Dual credibility assessments
| Assessment | Primary phase | Role |
|---|
| M&S capability | Development / release | How strong is the M&S product? |
| M&S results | Use / analysis | How credible is this analysis outcome? |
Use chain
Intended use → (develop) permissible uses + V&V domains → (operate) proposed use + appropriateness assessment.
Reporting control
Decision briefings carry warnings, uncertainty+method, assessment outcomes vs thresholds, reviews, qualifications, records, and risk-acceptance rationale — not plots alone.

Scope & Limits
This pack covers NASA-STD-7009B (approved 2024-03-05) together with NASA-HDBK-7009B (2026-02-03) as synthesized reference notes from a two-PDF extraction (metadata pages 88 + 175 = 263 source_pages). It does not reproduce the full requirements compliance matrix verbatim, replace delegated Technical Authority direction, fully detail NPR 7150.2 software engineering requirements, or teach end-to-end probabilistic risk assessment methods (see nasa-pra / nasa-risk). US Government public domain work. No source-material download link is published.
