Understanding Release Readiness
How we calculate. Readiness % = (met ÷ total checklist items) × 100. See our methodology and accuracy policy .
Real-world scenario: A typical Release Readiness case uses exit criteria met 17 and total exit criteria 20. Enter the same figures below to reproduce the worked path.
What is Release Readiness?
A simple go/no-go progress metric. Weight critical criteria separately in your process even if this calculator treats items equally.
- Define the checklist before the release train starts
- Critical fails can block even at high overall %
- Update daily in the hardening sprint
The Formula
Worked Example
Common Use Cases
- Go-live reviews: show checklist progress
- Risk conversations: highlight unmet critical items
- Program reporting: one readiness number for leadership
Pro Tips
- Tag must-pass items so 85% with a failed security gate still means no-go
- Keep evidence links next to each criterion
- Do not game the denominator by removing hard items
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
Limitations: Release Readiness results are planning aids for Agile/QA teams—not contractual delivery commitments. Confirm definitions with your scrum/quality playbook.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
When to use this calculator
- Use this page when your wording matches release readiness and the form labels on screen.
- Use percent of a number for “what is X% of Y?” problems.
- Use number is what percent when you know part and whole and need the percent.
