Disaster Recovery Readiness Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Readiness score = weighted average of restore tests 25%, runbooks 20%, backup success 20%, dependencies 15%, owner assignment 10%, and exercise recency 10%.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Restore Test Pass Rate: 85%
- Runbook Coverage: 80%
- Backup Success Rate: 96%
- Dependencies Mapped: 70%
- Owner Assigned: 90%
- Days Since Exercise: 120 days
- Exercise Recency Target: 180 days
- Target Readiness: 85%
Expected outputs
- Readiness Score: 82.62%
- Gap to Target: -2.38%
- Readiness Level: Moderate readiness
- Lowest Driver: Exercise recency
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Inputs are user-entered and processed locally in the browser.
- The calculator uses transparent deterministic formulas rather than vendor-specific risk, compliance, or availability models.
- Validate outputs against local policy, contracts, audit evidence, clinical safety requirements, and compliance obligations before taking action.
Unit handling
- Restore Test Pass Rate accepts values in %.
- Runbook Coverage accepts values in %.
- Backup Success Rate accepts values in %.
- Dependencies Mapped accepts values in %.
- Owner Assigned accepts values in %.
- Days Since Exercise accepts values in days.
- Exercise Recency Target accepts values in days.
- Target Readiness accepts values in %.
- Readiness Score is displayed as a percentage.
- Gap to Target is displayed as a percentage.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Percent outputs are displayed with two decimal places.
- Input precision follows configured step values where provided.
