Ranked by overall score (1-10), the average of Impact, Feasibility, Cost to implement (lower is better, flipped).

  1. Pareto Scrap by Defect

    9.0

    Rank defect codes by weekly scrap cost to focus action on the largest loss.

    Impact 9/10Feasibility 9/10Cost to implement 2/10 (lower is better)
    • Normalize Defect Code Rules

      8.0

      Audit 30 recent rejects against a shared codebook to prevent one defect splitting across labels.

    • Price Rework Disposition

      7.0

      Include labor, replacement material, and disposal fees so rankings reflect full defect cost.

    • Trace Scrap to Workcell

      6.7

      Add machine and operation IDs to each record to reveal localized losses hidden by plant-wide totals.

  2. Verify Incoming Material Lots

    7.7

    Track scrap by supplier lot and quarantine batches linked to recurring defects.

    • Run Risk-Based Receipt Sampling

      7.3

      Use AQL plans for high-risk suppliers and compare incoming defect rates before releasing stock.

    • Add Lot Barcode Genealogy

      7.0

      Scan supplier lot IDs at each workcell to connect finished scrap events to exact material batches.

    • Audit Supplier Process Changes

      6.3

      Require advance notice of tooling, resin, or sub-tier changes that can shift material properties.

  3. Lock Critical Process Settings

    7.3

    Compare scrap spikes with machine logs, then set alarms for pressure, temperature, or speed drift.

    • Version Recipe Changes

      7.7

      Require engineer approval and retain before-and-after settings to trace scrap after parameter edits.

    • Add PLC Limit Interlocks

      6.7

      Block cycle starts when pressure, temperature, or speed exceeds validated recipe limits.

    • Trend Sensor Drift

      6.7

      Compare sensor readings with a reference weekly; gradual bias can hide inside alarm thresholds.

  4. Calibrate Inspection Gauges

    7.3

    Run gauge repeatability checks to catch false rejects and inconsistent operator measurements.

  5. Control Shift Handoffs

    6.0

    Record first-piece results and open machine issues at every shift change to prevent repeat setup errors.
