qa-metrics
把指标与具体行动绑定，帮助仪表盘成为有效反馈回路
定义并跟踪关键 QA 指标（覆盖率、波动率、缺陷逃逸率等）并给出应对动作。
把 QA 的关键指标量化、跟踪并告诉你指标变坏时该怎么做，涵盖覆盖率、波动率（flakiness）、缺陷逃逸率、MTTR、执行时间等。在需要设定质量 KPIs、看板或判断测试健康时用，能把仪表盘从“好看”变成真正的反馈回路。特别之处是每个指标都有公式、合理目标、负责人和红灯时的具体应对动作。

Define, track, and act on QA metrics: test coverage percentage, flakiness rate, defect escape rate, MTTR, test execution time trends, automation ROI, quality gates, and SLAs for test suites. Includes metric formulas, realistic targets by company stage, and the action to take when each metric goes red. Use when: "QA metrics," "test metrics," "quality KPIs," "test health," "flakiness rate," "defect escape rate." Not for: building the dashboard UI (Allure/Grafana) — use qa-dashboard; measuring coverage gaps and mutation score — use coverage-analysis. Related: qa-dashboard, coverage-analysis, ci-cd-integration, release-readiness, quality-postmortem.

This skill defines the metrics that actually change behavior — each one with a formula, a target, an owner, and a concrete action when it goes red — so the dashboard becomes a feedback loop instead of decoration. </objective> ## Quick Route | Your situation | Metric to reach for | Section / reference | |---|---|---| | No metrics yet, where to start | code coverage, flakiness, defect escape | Core Principles + `references/rollout.md` | | Bugs escaping despite high coverage | defect escape rate + mutation score | Coverage Metrics, Defect Metrics | | Tests flaky, devs
