# Packaging engineering internships: protection, cost and a test-plan portfolio

## Find the damage-rate break-even point

Original fictional package comparison. Damage rates and loss costs are assumptions, not observed performance.

### Package and loss inputs

| Input | Package A | Package B |
| --- | --- | --- |
| Package cost per shipment | $0.80 | $1.10 |
| Assumed damage rate | 2.0% | 0.8% |
| Incremental loss per damaged shipment | $40 | $40 |
| Extra assembly time relative to A | 0 seconds | 12 seconds |

## Your turn

Calculate expected package-plus-damage cost. Then include incremental assembly at $24/hour and find the maximum B damage rate that would make B strictly cheaper.

## Your answer

[Write your approach here.]

## For your own application

List the validation and transition costs excluded from the model and propose how the damage-rate assumptions would be investigated.
