When to use

Use this pack when you need NASA's systems-engineering process model: the SE Engine and the 17 common technical processes, the program/project life cycle (Pre-Phase A → F), Key Decision Points and technical reviews (MCR, SRR, SDR, PDR, CDR, SAR, ORR, FRR), stakeholder expectations → technical requirements → logical decomposition → design solution, product verification vs validation, and crosscutting technical management (planning, risk, configuration, interfaces, data, assessment, decision analysis). Strong for aerospace/spaceflight project SE and lifecycle gating. Less suited to general MBSE notation or AI integration.

Prerequisites: none — this pack is plain Markdown; no MCP server, API key, or licence tier is needed at runtime.

How to Use This Skill

• Without arguments — load the core process model below for reference.
• With a topic — ask about verification vs validation, PDR, trade studies, configuration management, or another indexed topic; I read the relevant chapter.
• With a chapter — ask for ch20 to load Design Solution Definition.
• Browse — ask "what chapters do you have?" for the full index.

Supporting files: glossary.md (108 terms), patterns.md (20 techniques), cheatsheet.md (decision rules, phase/KDP/review gates, cost thresholds).

Core Frameworks & Mental Models

The SE Engine (Ch 1–3). NASA's central model: the 17 common technical processes arranged as three families — system design (4 processes: stakeholder expectations, technical requirements, logical decomposition, design solution), product realization (5: implementation, integration, verification, validation, transition), and technical management (8: planning, requirements management, interface management, risk, configuration, data, assessment, decision analysis). The engine is applied recursively down the product hierarchy and iteratively within each life-cycle phase.

Program/project life cycle (Ch 7–16). Phases Pre-Phase A (concept studies) → A (concept & technology development) → B (preliminary design) → C (final design & fabrication) → D (assembly, integration, test, launch) → E (operations) → F (closeout). Phase transitions are gated at Key Decision Points (KDPs) and supported by technical reviews (MCR, SRR, SDR/MDR, PDR, CDR, SIR, TRR, SAR, ORR, FRR).

System design flow (Ch 17–20). Stakeholder Expectations (captured as Needs-Goals-Objectives, ConOps, and Measures of Effectiveness) → Technical Requirements (validated, verifiable, with MOPs/TPMs) → Logical Decomposition (functional architecture, Product Breakdown Structure) → Design Solution (trade studies + decision analysis selecting the baseline).

Product realization (Ch 21–25). Implementation (make/buy/reuse) → Integration → Verification ("built it right" — test, analysis, inspection, demonstration) → Validation ("built the right thing" — against stakeholder expectations) → Transition. Verification and validation are distinct and both required.

Crosscutting technical management (Ch 26–34). Technical Planning (WBS, SEMP), Requirements Management (traceability, change control), Interface Management, Technical Risk Management (continuous, risk-informed decision making), Configuration Management, Technical Data Management, Technical Assessment (TPMs, EVM, reviews), and Decision Analysis (structured trade studies).

Scope & Limits

This pack covers NASA/SP-2016-6105 Rev 2 only. It is NASA-specific: the process model, Key Decision Points, technical reviews, and tailoring are framed for NASA programs/projects (and reference NPR 7123.1), with an aerospace/spaceflight emphasis. It is strong for lifecycle process, gating, V&V, and technical management; it is not a modelling-notation reference (use the SysML pack) and does not address AI/ML integration. The source is a US Government work in the public domain.
