Formula used

The calculator uses a weighted scoring model. Each readiness factor receives a score between 0 and 100, then multiplies by its assigned weight.

Release Readiness Score = Σ(Factor Score × Weight)

Defect Health Score = max(0, 100 − 18×Critical − 6×High − 2×Medium)

Security Readiness = max(0, Security Review Completion − 15×Open Security Findings)

Risk Control Score = max(0, 100 − 10×Open Risks − 15×Sev1 Incidents)

Factor	Weight
Requirements completion	10%
Test pass rate	12%
UAT sign-off	10%
Documentation completion	6%
Deployment readiness	8%
Monitoring readiness	7%
Rollback readiness	7%
Performance validation	10%
Security readiness	12%
Support readiness	5%
Defect health score	8%
Risk control score	5%

Blocker rules override strong scores. Open critical defects, weak rollback plans, weak UAT approval, or multiple unresolved security findings can force a no-go decision.

FAQs

1. What does this score measure?

It measures how prepared a release is across delivery, quality, security, support, and operational control areas. The result combines weighted readiness signals and blocker rules.

2. Why are defects converted into a score?

Raw defect counts are hard to compare with percentages. Converting them into a health score lets the calculator blend defect exposure with other readiness inputs consistently.

3. Can a high score still produce a no-go result?

Yes. Blockers can override a strong weighted score. Open critical defects, poor rollback readiness, weak UAT approval, or unresolved security findings can stop release approval.

4. What threshold values should I use?

Many teams use 70% for caution and 85% for go. You can raise them for critical systems or lower them for internal low-risk releases.

5. Is this calculator useful for sprint or hotfix releases?

Yes. You can use the same framework for large launches, routine deployments, and hotfixes. Teams often adjust thresholds and expected support readiness by release type.

6. Why include monitoring and rollback readiness?

A release is not safe if teams cannot detect issues quickly or reverse deployment cleanly. Those controls reduce outage duration and improve operational confidence.

7. What should I do after seeing a conditional result?

Review the warnings, improve the weakest factors, and recalculate. Conditional results usually mean release is possible, but the team should close specific gaps first.

8. Does this replace governance reviews?

No. It supports governance reviews by making release status measurable. Final approval should still consider business timing, compliance needs, and leadership judgment.
