Reliability Metric

Why Time-to-Detection Matters
More Than Time-to-Repair

A fast fix is not enough if the system spent hours hiding the need for one.

Time-to-repair gets attention because it feels active. Engineers diagnose, patch, deploy, and confirm. But time-to-detection often determines the true blast radius. If discovery is slow, even a brilliant repair arrives late.

For operational software, detection can be harder than repair. The code may fail in a way that looks like normal quietness. It may produce no exception. It may finish with partial results. It may succeed technically while failing the business process it exists to support.

Optimise for knowing sooner

OpenTrace improves the earlier part of the incident lifecycle. By emitting progress, notes, metrics, payloads, and milestones, software creates evidence while it works. Faster detection means smaller cleanup, clearer response, and less dependence on customers or humans noticing silence.
