Why 90% Test Coverage Still Fails

Most teams measure the wrong things—and wonder why quality doesn't improve. Jani Grönman explains the countermetric rule that changes everything. "If you cannot measure what you change, it's really hard to lead the change." - Jani Grönman In this episode, I talk with Jani Grönman about KPIs for quality. We ask what to measure, and why. Jani shares pairs that keep teams honest. Test pass rate with escaped defects or flaky tests. Mean time to recovery with reopen rate. Lead time to production with customer impact. One team, one number. Keep it to three or four KPIs, own them, and act. We talk about agency at work and product sense. Your tests are not a scoreboard. They are a feedback loop. Bring product and engineering together, do root cause analysis. I left inspired to pick fewer numbers, tell stories, and ship with care. 00:00 Importance of KPIs in Business 05:07 Balanced Metrics for Effective KPIs 08:08 One Team, One Metric 12:11 Keep Metrics Simple and Focused 16:46 Understanding Testing Limits and Metrics 19:21 Improving Testing Through Requirement Analysis 22:47 Building Metrics for Improvement 📘 Free e-book: The 7 success factors of software testing. 25 years of project experience in one 33-page workbook, now also in English 👉 https://tul.fm/ebook 🎯 Highlights: Every KPI needs a counter metric: measuring mean time to resolve bugs without also tracking reopen rate invites teams to close tickets without actually fixing the underlying problem. Teams should own no more than three or four KPIs at once, because a focused set drives direction while a long list produces noise and diffuses accountability. A metric nobody acts on is a useless metric: ownership and periodic review are what separate a meaningful KPI from a number that decorates a dashboard. Involving the team in building their own metrics creates genuine ownership, which is the difference between engineers who game a number and engineers who care about what it measures. High unit test coverage can coexist with production defects, making escaped defect rate the necessary counterweight to any pass-rate or coverage percentage metric. 🔗 Links Blog Post for Episode: https://www.richard-seidl.com/en/podc... 🎙️ More from Richard Seidl Website: https://www.richard-seidl.com Linkedin:   / richardseidl   Podcast Software Testing: https://www.testing-unleashed.fm #softwaretesting #QA #qualitymetricssoftwaretesting
