Integration Defect Rate at 1.44% target maximum error rate: a worked example

This worked example runs the integration defect rate numbers for a tougher week than the baseline: 1.44% target maximum error rate instead of the typical 2%. Calculate the defect or error rate for a software integration by dividing failed transactions by total transactions, then comparing against your target threshold.

The inputs for this scenario

  • Failed or errored transactions: 47 count (held at the documented default)
  • Total transactions in period: 5,000 count (held at the documented default)
  • Target maximum error rate: 1.44 % (the input this scenario stresses; the baseline uses 2)

Working through the calculation

  • The calculation starts from the formula this tool documents: Integration error rate = (failed transactions / total transactions) x 100.
  • Integration error rate works out to 0.94 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target error rate works out to 0.5 points at these inputs.
  • Failed transactions works out to 47 count at these inputs.
  • Total transactions works out to 5,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum error rate sits at 2% and the headline result is 0.94 %, this scenario lands almost exactly on the baseline at 0.94 %.
  • Use it for SLA reporting, post-incident review, or to decide whether an interface needs hardening. 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.

Results at a glance

  • Integration error rate: 0.94 % (headline result)
  • Gap to target error rate: 0.5 points
  • Failed transactions: 47 count
  • Total transactions: 5,000 count

Run it with your numbers

  • To rerun this with your own numbers, open the live Integration Defect Rate calculator, set target maximum error rate to your actual value, and adjust the remaining inputs to match your operation.
