    The policies start from identical drafts. Flagged drafts are reviewed; good drafts stay good. Review recovery applies to failed drafts sent to review. Generation, gate and review are operating resource costs; the failure consequence is separate and must not duplicate costs already counted. Setup, shared operation and review delay are excluded. Expected counts may be fractional.

    YOUR SCENARIO

    Selective operating cost
    $300.00
    Selective expected consequence
    $800.00
    Selective combined total
    $1,100.00
    Automatic-release combined total
    $2,100.00
    Universal-review combined total
    $1,600.00
    Selective final failures
    40
    Selective review hours
    4
    Quality among automatic releases
    95.45%

    The lowest combined cost can still violate an outcome or process requirement. Apply mandatory constraints, check uncertainty and measure review capacity before choosing a policy.

    Try the printed exercise

    Change the failure consequence from $20 to $50. Selective review rises to $2,300 while universal review stays at $1,600 under perfect recovery. Then reduce recovery to 99% and inspect the remaining failures.
