There's a moment after every release when you start to wonder whether you caught enough issues to safeguard your product. Most teams know that feeling well. You're stretched thin, asked to ship every new feature fast, and expected to do it without letting anything slip through that drives customers away.
But when you have to make tradeoffs between speed and quality, critical issues can slip through the cracks. So we went looking for answers to give QA teams the insights they need to understand where products commonly fail, strengthen their testing processes, and ship fewer bugs.
Testlio’s 2026 Software Quality Report combines external research with our own data from the last 12 months to surface the trends and failure patterns shaping software quality today.
You’ll learn:
- Why high-severity defects remain common, even in mature testing organizations
- Where the most serious defects occur and why
- What a single minute of downtime costs
- What our AI study taught us about safety, reliability, and accuracy
- Why real-world validation is becoming more important now than ever before
