When to use

Use this skill when you need to reason about the Department of Defense Digital Engineering Strategy (2018, OUSD/ODASD(SE)) and its five goals: (1) formalize the development, integration, and use of models; (2) provide an enduring authoritative source of truth; (3) incorporate technological innovation; (4) establish supporting infrastructure and environments; and (5) transform the culture and workforce. This pack also covers model formalisms, provenance, governance and access control of the authoritative source of truth, and the coordinate-plan-pilot-sustain rollout sequence. It is a vision-and-policy source, not a how-to method or tool tutorial.

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: the definition of digital engineering, the five goals, and the central mental-model shifts.
• With a topic — ask about a goal or focus area (e.g. "authoritative source of truth", "model formalisms", "Goal 4 infrastructure", "culture and workforce"), a shift (document-to-model, model-analyze-build), or a cited example (USS Ford, A-10, ERS, NAVAIR, Army LPDM/ePDM).
• With a chapter — ch01 (intro/vision + the five goals), ch02–ch06 (Goals 1–5), ch07 (next steps + Appendix 1 summary).
• Read it as intent, not procedure — the Strategy is a non-prescriptive "living document"; the concrete "how" lives in DoD Component implementation plans, which this pack does not contain.

Core Frameworks & Mental Models

What digital engineering is

Digital engineering is an integrated digital approach that uses authoritative sources of system data and models as a continuum across disciplines to support lifecycle activities from concept through disposal. The 2018 Digital Engineering Strategy — authored by ODASD(SE) with government, industry, and academia stakeholders — is the governing document. It is deliberately a vision and a compass, not a checklist: explicitly non-prescriptive and meant to evolve, it sets shared direction while the concrete execution lives in DoD Component / Service implementation plans.

The driver is mission urgency: deliver capability to the warfighter faster amid exponential technology change, rising complexity, tight budgets, and compressed schedules — problems the legacy linear, document-heavy, stove-piped process handles poorly. The system of interest is scoped broadly: systems of systems, systems, processes, equipment, products, and parts.

The Five Digital Engineering Goals

The entire Strategy is organized around five goals (Section IV summary; each expanded into focus areas in Section V):

1. Formalize the development, integration, and use of models — making modeling deliberate practice that informs enterprise- and program-level decisions. → ch02
2. Provide an enduring, authoritative source of truth — move the primary means of communication from documents to digital models and data. → ch03
3. Incorporate technological innovation to improve the engineering practice (beyond traditional model-based methods). → ch04
4. Establish a supporting infrastructure and environments so stakeholders can perform activities, collaborate, and communicate. → ch05
5. Transform the culture and workforce — equipping the Department to adopt digital engineering, and sustain it, across the lifecycle. → ch06

Read goals 1–4 as building the machine (models, a trusted data backbone, infused technology, the environment to run them in) and goal 5 as building the people who run it. Adoption is the gating risk.

Goal → focus-area structure

Each goal decomposes into numbered focus areas (Appendix 1 is the full map):

• Goal 1: 1.1 plan for models · 1.2 develop/integrate/curate models · 1.3 use models in decisions.
• Goal 2: 2.1 define the authoritative source of truth · 2.2 govern it (access, controls, governance) · 2.3 use it across the lifecycle.
• Goal 3: 3.1 establish an end-to-end digital engineering enterprise · 3.2 use technological innovations to improve the practice.
• Goal 4: 4.1 IT infrastructures · 4.2 methodologies · 4.3 secure infrastructure & protect IP.
• Goal 5: 5.1 improve the knowledge base · 5.2 lead & support transformation · 5.3 build & prepare the workforce.

Key constructs

• Authoritative source of truth (AST) — the single, trusted central reference for models and data; captures the current state and history of the technical baseline, gives traceability as the system evolves, and propagates changes downstream. Its authority comes from governance: governance → data quality → stakeholder confidence → data-driven decisions.
• Model formalisms — the quality rules (syntax, semantics, lexicons, standards) that let independently authored models combine into one coherent digital representation.
• Provenance and pedigree — recorded model origin and lineage that, with V&V-based reviews, make a model trustworthy and reusable. Trust is engineered, not assumed.
• Continuum of models — the same authoritative models carried and reused concept→disposal, not rebuilt at each phase boundary.

The mental-model shifts

• Documents → models/data as the primary means of communication; documents become generated views, and stakeholders shift from accepting documents to accepting models.
• Design-build-test → model-analyze-build — analyze and prove decisions in a virtual environment before physical build and fielding (virtual-first).
• Many copies → one source of truth — ask "is this traced from the AST?" not "which copy is current?"
• Stove-piped IT → a consolidated, collaborative, trusted environment (Goal 4's diagnosis and target).
• Lock-in → standards & interfaces — bet on the seams between tools (standards, data, formats, interfaces), not a vendor product.
• One-time rollout → sustained socio-technical change — culture is the operating system (Goal 5).

Rollout: coordinate → plan → pilot → sustain

The Strategy sequences four next steps: coordinate (ODASD(SE) convenes a summit and runs the standing Digital Engineering Working Group), develop implementation plans (owned by the DoD Components), implement pilot programs (learn/measure/optimize before scaling into major programs), and sustain (policy, guidance, training, continuous improvement). Ownership is distributed (Components own plans); coordination is central (ODASD(SE) is a gap-closer, not a gatekeeper).

Scope & Limits

Covers: the DoD Digital Engineering Strategy (2018) in full — the definition and vision of digital engineering; the five goals and their focus areas; the document-to-model and design-build-test→model-analyze-build shifts; model formalisms, provenance/pedigree, and model-based reviews; the authoritative source of truth (define/govern/use, governance, access control, technical baseline); the end-to-end digital enterprise, data-driven decisions, human-machine interaction, and technology insertion; supporting infrastructure, methodologies, cybersecurity, and IP protection; the culture/workforce transformation and its enablers; and the coordinate→plan→pilot→sustain rollout with its cited Service examples (USS Ford, Army LPDM/ePDM, A-10, ERS, NAVAIR).

Does not cover: this is a vision-and-policy strategy, deliberately non-prescriptive — it provides no step-by-step method, tool tutorials, or implementation procedure. It is thin on quantitative metrics, detailed acquisition-policy mechanics, and the contents of DoD Component implementation plans (which it points to but does not contain). For MBSE/SysML mechanics use the sebok pack and SysML v2 / Cameo tooling; for SE process detail use dau-se-guidebook; for systems-security-engineering depth use nist-sse; for open/modular architecture see dod-mosa. The CAC-gated Digital Engineering Body of Knowledge (DEBoK) is intentionally excluded (not public).
