nasa-ms-7009

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

  1. Programmatics — intended use, criticality, plan, metrics, acceptance criteria, reviews, defects.
  2. Development — RWS/pedigree, CM of data/software, units, assumptions, math, limits, permissible uses, capability assessment, guidance; plus V&V and development uncertainty.
  3. Use and reporting — proposed use, appropriateness, inputs, setup, envelope control, messages, results assessment, risk, decision reporting.

Dual credibility assessments

AssessmentPrimary phaseRole
M&S capabilityDevelopment / releaseHow strong is the M&S product?
M&S resultsUse / analysisHow 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.

Knowledge pack from 'Towards Digital Engineering: The Advent of Digital Systems Engineering' (Huang et al., Old Dominion University, arXiv:2002.11672, 2020). Use when reasoning about digital engineering, the DoD Digital Engineering Strategy and its five goals, the Authoritative Source of Truth, digitalization vs. digitization, digital augmentation, digitalized models, provenance, unique identification, and the four-level (vision/strategy/action/foundation) DSE research framework. Covers the conceptual/vision layer of the field. SCOPE LIMITS: this is a single ~28-page vision paper, not a methods handbook — it is thin on step-by-step procedures, tooling, case studies, and quantitative evaluation, and it predates 2020 so it does not cover later digital-engineering standards or recent AI/LLM advances. Use the sebok pack for established SE canon and MBSE depth.
