What problem does it solve? Long-lived defense systems outlast the technology inside them, so parts, materials, and software lose their manufacturers and suppliers. This Skill gives an agent structured knowledge from the SD-22 DMSMS Guidebook to manage that obsolescence risk across a system's life cycle instead of reacting to shortages after they hit readiness and cost. ## Core Features & Use Cases - Five-Step Process Guidance: Covers Prepare, Identify, Assess, Analyze, and Implement plus the Strategize overlay, including standing up a DMSMS Management Team (DMT) and Management Plan (DMP). - Risk-Based Monitoring: Explains the two-filter prioritization, the risk cube (criticality, supply-chain vulnerability, time to resolve), predictive tools, vendor surveys, and GIDEP/DLA product discontinuance notices. - Resolution Costing and Funding: Details resolution categories (existing material, substitutes, redesign), AoA/BCA comparison on net present value, life-of-need buy sizing, modification funding, and the ECP process. - Use Case: A sustainment engineer asks how to handle a flagged obsolete component; the agent walks through the Assess gate (need, timing, level), a health assessment with days-of-supply, and a costed resolution comparison. ## Quick Start Ask the agent to use the sd-22-dmsms skill to explain how to assess and resolve an obsolescence issue flagged on a system component.
