  1. A packaging engineer notices that defect rates spike every Monday morning. Which type of analysis best identifies this pattern?

    Answer: Time-series analysis

    Time-series analysis tracks data points over time, making it ideal for identifying cyclical or day-of-week patterns in defect rates.

  2. When creating a control chart for a packaging line's fill weight, the process shows all points within control limits but exhibits a run of 8 consecutive points above the centerline. This indicates:

    Answer: A potential process shift requiring investigation

    A run of 8 or more consecutive points on one side of the centerline is a non-random pattern indicating a potential process shift, even when within control limits.

  3. Which metric best measures the efficiency of packaging material usage relative to finished goods produced?

    Answer: Material yield rate

    Material yield rate measures the proportion of input material that becomes usable finished product, directly reflecting packaging material efficiency.

  4. In a packaging cost report, fixed overhead is allocated at $2.50 per unit at 100,000 units/month production. If production drops to 80,000 units, what is the new overhead rate per unit?

    Answer: $3.125

    Fixed costs remain constant ($250,000 total), so dividing by 80,000 units gives $3.125 per unit — fixed costs per unit rise as volume falls.

  5. A scatter plot comparing seal strength versus sealing temperature shows an R² value of 0.89. This means:

    Answer: Temperature explains 89% of the variation in seal strength

    R² (coefficient of determination) indicates what percentage of variability in the dependent variable is explained by the independent variable.

  6. Which dashboard KPI would be MOST useful for a packaging manager trying to reduce customer complaints about damaged goods?

    Answer: Transit damage rate

    Transit damage rate directly measures how frequently packages are damaged during shipping, which is the primary driver of customer damage complaints.

  7. A Gauge R&R study for a packaging seal inspection system shows 35% of total variation is attributable to measurement system variation. This result indicates:

    Answer: The measurement system needs improvement before use

    Industry standards generally require measurement system variation below 10% (acceptable) or 10–30% (marginal); 35% is unacceptable and requires improvement.
