Worked Example: DORA Engineering Metrics Tier Worked Example
Benchmark software delivery velocity & stability against DORA Elite, High, Medium, and Low tiers.
- Enter the input measurement, system configuration, or astronomical parameter.
- Apply the standard conversion or analytical equation: DORA_Score = 0.25×(DeployScore + LeadTimeScore + CFR_Score + MTTR_Score); AnnualFailedDeploys = DeploysPerMonth × 12 × CFR%.
- Inspect the primary metric, secondary equivalents, and 3 real-time SVG graphs.
Result: Computes DORA Engineering Metrics Tier via DORA_Score = 0.25×(DeployScore + LeadTimeScore + CFR_Score + MTTR_Score); AnnualFailedDeploys = DeploysPerMonth × 12 × CFR%.

DORA Engineering Metrics (Deploy Frequency, Lead Time, CFR & MTTR) Tier Calculator: inputs, method, and how to read the result
Benchmark software delivery velocity & stability against DORA Elite, High, Medium, and Low tiers.
Choose inputs for the case you are checking
The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.
- Deployments Per Month: Production deployments per month (≥30 = daily/on-demand Elite; 4–29 = weekly High; 1–3 = monthly Medium).
- Lead Time For Changes Hours: Median hours from code commit to production running (<24h Elite; 24–168h High; >168h Medium/Low).
- Change Failure Rate Pct: Percentage of deployments causing production degradation or rollback (≤5% Elite; 5%–15% High).
- Mean Time To Recovery Hours: Mean time to restore service after a failed deployment (<1h Elite; <24h High).
What the calculation includes
With the default values shown, Composite DORA Engineering Score is 100 / 100 (DORA Elite Performer). The calculation follows DORA Engineering Metrics Tier Formula; the formula and variable definitions above show how the inputs combine.
A question to settle before using the estimate
How does the DORA Engineering Metrics (Deploy Frequency, Lead Time, CFR & MTTR) Tier Calculator perform the calculation? It evaluates DORA_Score = 0.25×(DeployScore + LeadTimeScore + CFR_Score + MTTR_Score); AnnualFailedDeploys = DeploysPerMonth × 12 × CFR% directly in your browser and renders three custom SVG charts in real time.
Where to use caution
- Uses official NIST Special Publication 811, IEEE/RFC systems engineering, APA psychometric, and USNO astronomical formulas.
- Empirical metallurgy and calendar conversions represent standard reference-condition approximations.
Scope: Global NIST, IEEE, APA & Astronomical Standard Check the assumptions and limitations against your situation before relying on the estimate.
