Failure analysis works at the Phase level. It ranks phases by how often they fail and how long they take, so you can target the weakest step in your test instead of guessing.

Phase failures

The Phase failures table lists every phase that has failed in the selected range, sorted by failure count. Phases that have never failed are hidden.

Click a phase to surface the Measurements that triggered the failures, then jump into Process Control to look at the Cpk and control charts for those measurements.

Phase durations

The Duration table lists phases by average wall-clock duration, longest first.

Click a phase to see daily duration over time. Use it to spot regressions after a Deployment or to find the bottleneck in a long procedure.

Filters

Failure analysis shares the analytics filter bar.

  • Date range: pick a preset or a custom window.
  • Source: choose user runs from the CLI or production runs from a Station.
  • Batch, procedure version, part name, and revision: slice the data the same way you would on the yield view.
