DECISION Repair-vs-buy decision support lead in an engineering support activity reviewing alternate sources must choose Fund and move materiel / Cannibalize or substitute / Defer a cycle / Hold using NSN demand-and-backorder extract after a repair cost that exceeds replacement by 3x.
HYPOTHESES TO TEST 1. Authorize Fund and move materiel now; NSN demand-and-backorder extract already has the discriminator after a repair cost that exceeds replacement by 3x. 2.

Quantify mission impact if cost history can support is deferred one cycle in an engineering support activity reviewing alternate sources. 4. For this Defense Sustainment Depot Procurement Intelligence file, read NSN demand-and-backorder extract against a repair cost that exceeds replacement by 3x and write the one fact that would move cost history can support for repair-vs-buy decision support lead.

The follow-on Depot Procurement Intelligence action is what repair-vs-buy decision support lead does next: implement the option, assign an owner, and log the missing fact.
COMMAND RETURNS - Bottom-line Defense Sustainment option on cost history can support, then the evidence in NSN demand-and-backorder extract, then the action for repair-vs-buy decision support lead - Hypothesis scorecard against NSN demand-and-backorder extract: supported / rejected / untestable - Missing page in NSN demand-and-backorder extract after a repair cost that exceeds replacement by 3x, if any - Regulatory or exam hook Depot Procurement Intelligence would cite
