When to use

Use this skill to manage obsolescence and supply loss on a system that must stay supportable for decades while commercial technology turns over in years. It covers the SD-22, 06-JAN-2026 discipline: set up a DMSMS program, decide what to watch, judge when an issue threatens cost/schedule/readiness, choose a durable resolution, fund and field it, and handle FMS partner configurations when DoD sells or supports them.

Prerequisites: none. Plain Markdown; no MCP server, API key, or licence tier needed at runtime.

How to Use This Skill

  • Without arguments - load the five-step spine, DMT/DMP infrastructure, monitoring model, and resolution logic below.
  • With a topic - ask about a step (Prepare/Identify/Assess/Analyze/Implement), FMS practice, a monitoring concept (predictive tools, PDN, vendor survey, critical materials), a resolution family (life-of-need buy, substitute, redesign, technology refreshment), or an artifact (DMT, DMP, health assessment).
  • With a chapter - ch03 (Prepare/DMT/DMP/FMS communication), ch04 (Identify/monitoring/BOM), ch05 (Assess/health assessment), ch06 (Analyze/BCA/security consideration), ch07 (Implement/funding/roadmaps), ch08 (obsolescence relationship).

State versus event. Obsolescence is a context-dependent state. A DMSMS issue is the event where supply cannot meet demand. Most DMSMS problems grow from obsolescence, but not all, and not every obsolete item is a DMSMS problem.

Core Frameworks & Mental Models

What DMSMS is

DMSMS is the loss or impending loss of manufacturers and suppliers of the items, materials, and software a system depends on. SD-22 frames management as risk-based, multidisciplinary, and life-cycle-long. Electronics, MaSME items, and software are all in scope.

Two mechanisms. First-order obsolescence comes from market or regulatory cuts to buy/license/support paths. Lower-order (derived) obsolescence is functional loss the program's own changes create.

The five-step process

  1. Prepare - foundations, DMT, DMP, operations funding, contracts, workforce, FMS communication.
  2. Identify - monitoring and surveillance into an issue list.
  3. Assess - whether, when, and at what level to resolve.
  4. Analyze - options, costs, BCA/AoA, security-engineering screen, preferred path.
  5. Implement - fund, field, close; align with mods and roadmaps.

This edition does not name a Strategize step.

FMS in this edition

Security-cooperation sales add communication paths in Prepare and step-level notes in Identify, Analyze, and Implement so partner configurations are not surprises.
