Introduction
In today’s software engineering, the pursuit of excellence hinges on efficiency, quality, and innovation. Engineering metrics, particularly the transformative DORA (DevOps Research and Assessment) metrics, are pivotal in gauging performance. According to the 2023 State of DevOps Report, high-performing teams deploy code 46 times more frequently and are 2,555 times faster from commit to deployment than their low-performing counterparts.
However, true excellence extends beyond DORA metrics. Embracing a variety of metrics—including code quality, test coverage, infrastructure performance, and system reliability—provides a holistic view of team performance. For instance, organizations with mature DevOps practices are 24 times more likely to achieve high code quality, and automated testing can reduce defects by up to 40%.
This benchmark report offers comprehensive insights into these critical metrics, enabling teams to assess performance, set meaningful targets, and drive continuous improvement. Whether you’re a seasoned engineering leader or a budding developer, this report is a valuable resource for achieving excellence in software engineering.

- Coding Time: The actual time developers spend coding. Elite teams manage this in <12 hours per PR.
- Issue Cycle Time: Time taken to resolve issues. Top-performing teams resolve issues in <12 hours.
- Issue Velocity: Number of issues resolved per week. Elite teams handle >25 issues weekly.
- Mean Time To Restore: Time taken to restore service after a failure. Elite teams restore services in <1 hour.
Quality Metrics
Quality represents the standard of excellence in development processes and code quality, focusing on reliability, security, and performance. It ensures that products meet user expectations, fostering trust and satisfaction. Quality metrics include:
- PRs Merged Without Review: Percentage of PRs merged without review. Elite teams keep this <5% to ensure quality.
- PR Size: Size of PRs in lines of code. Elite teams maintain PRs to <250 lines.
- Average Commits After PR Raised: Number of commits added after raising a PR. Elite teams keep this <1.
- Change Failure Rate: Percentage of deployments causing failures. Elite teams maintain this <15%.
Throughput Metrics
Throughput measures the volume of features, tasks, or user stories delivered, reflecting the team’s productivity and efficiency in achieving objectives. Key throughput metrics are:
- Code Changes: Number of lines of code changed. Elite teams change <100 lines per PR.
- PRs Created: Number of PRs created per developer. Elite teams average >5 PRs per week per developer.
- Coding Days: Number of days spent coding. Elite teams achieve this >4 days per week.
- Merge Frequency: Frequency of PR merges. Elite teams merge >90% of PRs within a day.
- Deployment Frequency: Frequency of code deployments. Elite teams deploy >1 time per day.
Collaboration Metrics
Collaboration signifies the cooperative effort among software development team members to achieve shared goals. It entails effective communication and collective problem-solving to deliver high-quality software products efficiently. Collaboration metrics include:
- Time to First Comment: Time taken for the first comment on a PR. Elite teams respond within <6 hours.
- Merge Time: Time taken to merge a PR after it is raised. Elite teams merge PRs within <4 hours.
- PRs Reviewed: Number of PRs reviewed per developer. Elite teams review >15 PRs weekly.
- Review Depth/PR: Number of comments per PR during the review. Elite teams average <5 comments per PR.
- Review Summary: Overall review metrics summary including depth and speed. Elite teams keep review times and comments to a minimum to ensure efficiency and quality.
Benchmarking Structure
Performance Levels
The benchmarks are organized into the following levels of performance for each metric:
- Elite – Top 10 Percentile
- High – Top 30 Percentile
- Medium – Top 60 Percentile
- Needs Focus – Bottom 40 Percentile
These levels help teams understand where they stand in comparison to others and identify areas for improvement.
Data Sources
The data in the report is compiled from over 1,500 engineering teams and more than 2 million pull requests across the US, Europe, and Asia. This comprehensive data set ensures that the benchmarks are representative and relevant.
