Measurable indicators to assess and steer software and process quality.
Quality metrics are measurable indicators to assess software and process quality. They enable objective evaluation of defect density, reliability, maintainability and test coverage and support data-driven improvement decisions. Their use includes data collection, instrumentation, trend analysis and dashboards for continuous monitoring. Metrics should be transparent, contextualized and aligned with business objectives.
Number of defects per LOC or function size; indicates code quality and release readiness.
Average time to recover after failure; central for reliability assessments.
Percentage of code paths covered by tests; helps reduce regressions.
Weekly reports combined issue data and release tags to prioritize hotfixes.
Monitoring dashboard with SLI trends, alerts and responsible runbooks.
Automated coverage reports during pull request checks to prevent regressions.
Define goals and relevant quality dimensions.
Document metrics with standardized calculation formulas.
Introduce instrumentation and automated data collection.
Establish dashboards, alerts and regular review cycles.
