DORA Metrics Calculator for Azure DevOps

🚀 Excited to share a Python-based DORA Metrics Calculator for Azure DevOps that I've been working on!

Why this is required?

During my learning about Engineering Metrics, I was trying to identify way to calculate measuring team performance, programmatically and you can find it here.

What you can do ?

This tool helps you track:

✅ Deployment Frequency (DF)
✅ Lead Time for Changes (LT)
✅ Change Failure Rate (CFR)
✅ Mean Time to Recovery (MTTR)

Key features

- Branch-specific metrics (perfect for tracking main/production branches)
- Customizable date ranges
- Detailed deployment pipeline analysis
- Easy integration with existing Azure DevOps projects

Tech stack

- Python
- Azure DevOps SDK
- Pandas for data analysis

I've made the code public for anyone who wants to use or improve it.
Required packages
- azure-core
- azure-devops
- pandas
- numpy

Sample Output

DORA Metrics for releases/v1 branch in Murali.HelloWorld:
Time Period: Last 15 days
Deployment Frequency: 28.20 deployments/day
Lead Time for Changes: 25.53 hours
Change Failure Rate: 1.32%
Time to Restore: 0.00 hours
