BOM Cost Review

Q: How do I know the BOM Cost Review output is good?

The skill verifies itself against its own quality checks: Rollup total reconciles with the sum of lines — no silent arithmetic drift; Every top-10 line has a lifecycle and sourcing note, even if `[missing — request]`; Each cost-down candidate names the lever, the saving, and the cut-in build/ECO; MOQ flags are computed against the stated forecast, not gut feel.

Review a bill of materials for cost, risk, and supply exposure — cost rollup, top-10 cost drivers, single-source and EOL risk, MOQ vs forecast mismatch, cost-down candidates, and tariff/logistics sensitivity. Use when asked to review a BOM, find cost-down opportunities, check component sourcing risk, or sanity-check BOM cost against target. Produces a structured BOM review with a cost driver Pareto, risk flags per line, and a prioritised cost-down list.

What to give it

▸The BOM — part numbers, descriptions, quantities, unit costs (any format; structure it)

▸Annual forecast volume — needed for MOQ math and price-break realism

▸Target BOM cost — what "good" looks like

▸Sourcing detail if available — approved vendors, country of origin, lead times, lifecycle status

▸Product stage — EVT-stage BOMs get design-out suggestions; MP-stage BOMs get negotiation/resourcing ones

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Rollup total reconciles with the sum of lines — no silent arithmetic drift

✓Every top-10 line has a lifecycle and sourcing note, even if `[missing — request]`

✓Each cost-down candidate names the lever, the saving, and the cut-in build/ECO

✓MOQ flags are computed against the stated forecast, not gut feel

✓Single-source flags distinguish "no alternate exists" from "alternate not yet qualified"

⚠️ What it refuses to do

Do not quote unit prices without a volume — a price without its quantity break is fiction

Do not chase pennies on passives while a top-10 line is single-sourced and EOL

Do not claim a cost-down saving without naming the lever and who has to act

Do not treat distributor stock as supply security for a single-source part

Do not ignore custom/tooled parts in risk review — they are the hardest to move
