Quality Control Failure: The Margin Drain of Re-Repairs
Why every device returned under warranty costs your business double—and how structural quality gates stop margin leakage.
The Deadly Cost of Warranty Redos
When a customer returns with a screen that is lifting, or a camera that stopped functioning after a battery replacement, your business takes a massive financial hit:
- **Double Part Cost**: You must consume another inventory item for free.
- **Technician Double Pay**: The employee’s time is wasted repairing the same device again.
- **Reputational Impairment**: Negative reviews drive away high-value retail traffic.
How iShopMaster Implements Structural QC Gates
In iShopMaster, a technician cannot mark a ticket as "Ready to Deliver" without passing through the **Mandatory Quality Control (QC) module** (`PATCH /api/v1/repairs/:id/qc`):
- **Multi-Point Hardware Verification**: Enforces checklist items for front camera, ambient light sensor, speakers, and proximity sensors.
- **Post-Assembly Hold Times**: Enforces diagnostic stress tests to verify battery draw safety and thermals.
- **Evidence Photos**: Captures high-definition outtake photos to prove the repair met strict visual criteria before handover.
