federal-bca

Knowledge base from OMB Circular A-94 (revised 2023-11-09) on guidelines and discount rates for benefit-cost and cost-effectiveness analysis of federal programs. Use for BCA principles, benefit/cost measurement, discount-rate policy, uncertainty/sensitivity, distributional incidence, and decision reporting. Rescoped at build to A-94 only (Army CBA Guide unreachable). Does not replace A-11 budget preparation detail, agency-specific statutory BCA rules, or Army CEAC process templates.

OMB Circular A-94 — Federal Benefit-Cost Analysis Guidelines

Source: OMB Circular A-94, revised Nov. 9, 2023 (US Government work, public domain) | Chapters: 6

When to use

Reach for this pack when designing or reviewing federal benefit-cost or cost-effectiveness analyses—especially discount-rate selection, baseline and opportunity-cost measurement, uncertainty/sensitivity, distributional incidence, and OMB-facing documentation quality for program or legislative decisions.

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 NPV, real vs nominal rates, opportunity cost, sensitivity, incidence, or CEA vs BCA.
  • With a chapter — ask for ch01 through ch06.

Supporting files: glossary.md, patterns.md, cheatsheet.md.

Core Frameworks & Mental Models

Why A-94 exists

Promote social welfare via well-informed federal decisions. Provides general BCA/CEA guidance and specific discount-rate policy for time-distributed benefits and costs. Revised 2023; rescinds 1992 A-94.

Mandatory vs suggested

ContextForce
Analyses to OMB under A-11 / A-19 / 1992 Presidential Memo estimatesMust follow
Internal Executive Branch planningSuggested
Law / EO / other circulars prescribe methodsThose control

Analysis spine

  1. Decision question + alternatives + baseline
  2. Identify/measure social benefits and costs (opportunity cost; transfers separated)
  3. Align inflation basis
  4. Discount with A-94 class-appropriate real/nominal rates
  5. Characterize uncertainty + sensitivity
  6. Report distributional incidence
  7. Document transparently for decision makers/OMB

BCA vs CEA

  • BCA: Monetize benefits and costs → discounted net benefits / NPV
  • CEA: When benefits fixed or not monetized → compare costs for effect (still discount correctly)

Pack scope note

Built as A-94 only after P7-PRE-2 dual-document gate: Army Cost Benefit Analysis Guide could not be retrieved (ASAFM host 403 from this environment). Do not expect Army CEAC step templates here.

Scope & Limits

This pack covers OMB Circular A-94, revised November 9, 2023 (28 pages per extraction metadata) as synthesized reference notes on federal BCA/CEA guidelines and discount-rate policy.

Rescope (P7-PRE-2): Planned dual source was A-94 + US Army Cost Benefit Analysis Guide. The Army PDF was not retrievable (ASAFM 403 / Wayback 503 from the build environment). Per hard gate rules, the pack was rescoped to the surviving in-source-clean document (A-94) rather than generating Army content without evidence. Re-expand if the Army guide becomes fetchable.

It does not cover: full OMB Circular A-11 budget formulation; agency-specific statutory BCA regimes; private-sector CFA/WACC practice as a substitute for A-94; or Army CEAC process templates. US Government public domain work. No source-material download link is published.

Signpost (not a knowledge pack) for the automotive standards landscape: ISO 26262, ASPICE, SAE J3016, UNECE R155, UNECE R156, and the NHTSA vehicle set. Contains NO source content: designation, edition, owner, status, and an official catalogue URL only. Use when you need to identify or locate an automotive standard. Most are paywalled or carry no redistribution grant and cannot be packaged; the one open path is the nhtsa-vehicle pack.

Signpost (not a knowledge pack) for the avionics development assurance standards landscape: RTCA DO-178C / EUROCAE ED-12C and its supplements (DO-330/ED-215, DO-331/ED-218, DO-332/ED-217, DO-333/ED-216); RTCA DO-254 / EUROCAE ED-80; SAE ARP4754B and ARP4761A; and the free regulator documents that recognise them (FAA AC 20-115D, AC 20-152A, Order 8110.49A; EASA AMC 20-115D and AMC 20-152A). Contains no source content: each row carries only the designation, title, edition, owner, redistributability status, and the owner's URL. Use when you need to identify, cite, or locate an avionics standard; paywalled rows point to the owner, free rows point to the regulator text, and the FAA rows also name the in-repo faa-8110-49 pack.

Knowledge base from the DoD Systems Engineering Guidebook (OUSD R&E, February 2022). Use for the DoD SE process model — the 16 SE processes (8 technical management + 8 technical) mapped to ISO/IEC/IEEE 15288, the event-driven technical reviews and audits across the Major Capability Acquisition life cycle (ASR, SRR, SFR, PDR, CDR, SVR/FCA, PRR, PCA), the Systems Engineering Plan (SEP), risk/issue/opportunity management, TPMs and leading indicators, system-of-systems and digital engineering, and the 24 design considerations (RAM, system safety, HSI, system security engineering, MOSA, supportability, etc.). Acquisition-program oriented: thin on detailed cost estimating, contracting law, and non-DoD or commercial life cycles.

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.
