A tool to calculate the DORA Lead Time metric

DORA Lead Time Metric

DORA Lead Time for Changes

Lead Time for Changes is one of the four key DORA (DevOps Research and Assessment) metrics that measure software delivery performance. It measures the time it takes from when code is committed to when it is successfully running in production. A shorter lead time indicates an organization's ability to respond quickly to customer needs and fix problems rapidly.

This Python package calculates lead time by connecting data from Jira and GitHub. The calculation involves going from Projects → Releases → Stories → Pull Requests → Commits, calculating the lead time for each pull request, and averaging those over a given time period.

How to Use

See Calculate the DORA Lead Time Metric in Python for a detailed explanation of how to use this code. The code is at sualeh/dora-lead-time-metric.

Build

Install

• Python 3.13 or higher
• Poetry (Python dependency manager)

Clone the repository:

git clone https://github.com/sualeh/dora-lead-time-metric.git
cd dora-lead-time-metric

Install dependencies using Poetry:

poetry install

Create an .env file in the project root based on .env.example

Activate the Poetry environment:

poetry shell

Run the main application:

python -m dora_lead_time.main

Generate reports with code similar to the following:

from dora_lead_time.lead_time_report import LeadTimeReport

# Initialize the report generator
report = LeadTimeReport("releases.db")

# Generate a monthly report
monthly_data = report.monthly_lead_time_report(
    ["PROJECT1", "PROJECT2"],
    date(2023, 1, 1),
    date(2023, 12, 31)
)

# Visualize the report
plt = report.show_plot(monthly_data, title="Monthly Lead Time", show_trend=True)
plt.savefig('lead_time_trend.png')
