"Time to Merge" Metric for Pull Requests
The Power of Tracking “Time to Merge”
In software development, tracking the right metrics is vital to ensure your team is both efficient and effective. There’s a multitude of software metrics out there, from code churn to lead time to deployment frequency. Among them, one stands out with its unique ability to provide insight into both the velocity and quality of your development process: Time to Merge.
What is “Time to Merge”?
The “Time to Merge” metric measures the time it takes from when a developer first submits a Pull Request (PR) until it’s finally merged into the main branch. This seemingly straightforward metric holds a treasure trove of information about your software team’s operational efficiency and collaboration dynamics.
Time to merge is sometimes abbreviated as “TTM”. When you track the “mean” or “average” time to merge, it’s abbreviated as “MTTM”.
“Time to Merge” vs “PR Lifetime”?
“Time to Merge” and “Pull Request Lifetime” are just two different names for the same thing.
Why “Time to Merge” Matters
Efficiency and Velocity: At its core, the time to merge provides a glimpse into how quickly your team is moving. Are PRs being merged within hours, days, or weeks? If it takes weeks to get a piece of code merged, it can indicate bottlenecks in your review process.
Quality Assurance
Rapid merging isn’t always a good sign. It might mean that PRs are not being reviewed thoroughly. A balanced time to merge indicates that the team is investing enough time for thorough code reviews, ensuring code quality and maintaining standards.
Collaboration Dynamics
The metric can also highlight collaboration challenges. Extended time to merge might mean that developers and reviewers are not in sync, perhaps due to lack of clear communication or misaligned priorities.
Resource Allocation
If you find certain PRs consistently taking longer to merge, it might indicate that the team lacks expertise in that specific area. This can help managers allocate training resources or hire for specific skill gaps.
Benefits of Tracking “Time to Merge”
-
Optimized Workflow: By understanding what’s causing delays in the merging process, team leads and managers can streamline workflows, introduce automation, or offer training to address specific challenges.
-
Improved Forecasting: For engineering managers and CTOs, having a grasp on the time to merge can assist in better release planning and setting more accurate timelines for stakeholders.
-
Boosted Morale: For developers, long waiting times can be demotivating. Addressing and reducing the time to merge can improve team morale, as developers see their work moving swiftly through the pipeline.
-
Enhanced Code Quality: Emphasizing an optimal time to merge ensures that code reviews are neither rushed nor neglected, fostering a culture of quality and attention to detail.
