Implantable Electronics & Neurodevices worked example
Field Complaint Cost at 1% expected complaint rate: a worked example in implantable electronics & neurodevices
This worked example runs the field complaint cost numbers for a tougher week than the baseline: 1% expected complaint rate instead of the typical 1.2%. Estimate field complaint handling cost for implantable electronics using shipped population, complaint cost, expected rate, and fixed investigation adders.
The inputs for this scenario
- Shipped devices in complaint scope: 8,000 devices (held at the documented default)
- Average cost per complaint: 980 $ / complaint (held at the documented default)
- Expected complaint rate: 1 % (the input this scenario stresses; the baseline uses 1.2)
- Fixed complaint investigation adders: 28,000 $ (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Variable field complaint cost = shipped devices in complaint scope × average cost per complaint × expected complaint rate.
- Total field complaint cost works out to 106,400 $ at these inputs, and this is the headline figure for the scenario.
- Complaint cost per shipped device works out to 13.3 $ / device at these inputs.
- Variable field complaint cost works out to 78,400 $ at these inputs.
- Fixed complaint investigation adders works out to 28,000 $ at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where expected complaint rate sits at 1.2% and the headline result is 122,080 $, this scenario comes in 12.84% below the baseline at 106,400 $.
- Use it when budgeting complaint-handling and post-market surveillance staffing, or when modeling the cost impact of a change in complaint rate. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
