Field Failure Cost at 40% events triggering full response: a worked example in wearable medical sensors

Suppose events triggering full response falls to 40%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the total cost of field failures for a deployed wearable medical sensor fleet.

The inputs for this scenario

  • Field Failure Events: 320 events (held at the documented default)
  • Cost to Resolve One Failure: 145 $ / event (held at the documented default)
  • Events Triggering Full Response: 40 % (the input this scenario stresses; the baseline uses 55)
  • Complaint Handling Infrastructure: 6,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Field failure cost = failure events x cost per event x (% full response) + infrastructure.
  • Total field failure cost works out to 24,560 $ at these inputs, and this is the headline figure for the scenario.
  • Field failure cost per unit works out to 76.75 $ / piece at these inputs.
  • Variable field failure cost works out to 18,560 $ at these inputs.
  • Fixed field failure cost adder works out to 6,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where events triggering full response sits at 55% and the headline result is 31,520 $, this scenario comes in 22.08% below the baseline at 24,560 $.
  • It computes total field failure cost and cost per event by applying the per-event resolution cost weighted by the escalation share, then adding fixed complaint-handling infrastructure. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total field failure cost: 24,560 $ (headline result)
  • Field failure cost per unit: 76.75 $ / piece
  • Variable field failure cost: 18,560 $
  • Fixed field failure cost adder: 6,000 $
