🎯 What Are Quality Gates
Quality gates enforce organizational quality policies and decide whether a release is ready to move forward. They act as automated checkpoints that validate software quality before allowing progression to the next pipeline stage.
⛔ Where Quality Gates Sit in the Pipeline
Quality gates are placed before critical stages that rely on earlier outcomes, such as:
- Merge to main
- Deployment to staging
- Promotion to production
Only when the gate conditions are met does the pipeline proceed ✅
🕰️ Traditional vs Modern Approach
🧑💼 Traditional QA
- Manual reviews
- Heavy documentation
- Human approvals
- Slow and error-prone
🚀 Continuous Delivery Reality
- Manual checks become bottlenecks
- Inconsistent enforcement
- Poor scalability
👉 Conclusion: Manual quality gates do not scale in modern CI/CD.
🤖 Automated Release Gates (The Right Way)
In Continuous Delivery, quality gates must be:
- Fully automated
- Policy-driven
- Pipeline-native
- Human-independent
Automated release gates continuously validate quality without slowing delivery.
✅ Common Quality Gate Checks
🐞 Code & Security
- 🚫 Zero new blocker or critical issues
- 🧪 Code coverage ≥ 80% on new or changed code
- 📦 No license violations
- 🔐 No known dependency vulnerabilities
- 🧹 Technical debt maintained or reduced
⚡ Performance & Reliability
- ⏱️ Performance benchmarks unchanged or improved
- 📉 No regression in key SLIs or SLOs
📜 Compliance & Governance Gates
- 🔗 Work item linkage verified (code ↔ ticket)
- 👥 Segregation of duties enforced (committer ≠ releaser)
- 🛡️ Policy compliance automatically validated
🧩 Why Release Gates Matter
✔ Consistent quality enforcement
✔ Faster, safer releases
✔ Reduced production risk
✔ Audit-ready pipelines
✔ Scalable governance
🏁 Final Takeaway
🚀 Quality gates must evolve from manual approvals to automated release gates.
When embedded into every deployment pipeline, they protect quality without sacrificing speed.
No gate passed. No release. No exceptions. 🔒
