What are Regressions? (Software Quality and Incident Response)

New Incident Response Frameworks Published

A regression is a software bug that causes a previously functioning feature to stop working after a new code change or deployment has been made. Regressions are a major risk in high-velocity development environments because they represent a step backward in product quality. They are typically caught by automated regression testing suites, but those that leak into production require immediate incident response.

Key Benefits of Regression Management

  • Maintains Product Stability: Rigorous regression tracking ensures that new features don't come at the cost of existing functionality.
  • Saves Development Time: Catching a regression early in the CI/CD pipeline is significantly cheaper and faster than fixing it after it has reached production users.
  • Protects Brand Reputation: Consistent product behavior builds user trust, while frequent regressions lead to a perception of "unreliable" software.

The All Quiet Bridge

All Quiet acts as the safety net for your deployment pipeline, alerting you to production regressions in real-time. By integrating your CI/CD tools and error trackers (like Sentry) with All Quiet, you ensure that any "new" bug introduced by a release triggers an immediate on-call notification. All Quiet helps your team identify which deployment caused the regression, allowing for a fast rollback and minimal user impact.
