30+ Software Engineering Metrics to Track in 2025

Tracking the correct software engineering metrics helps organizations to improve product quality, team performance, and delivery efficiency.

These metrics help in strong decision-making, support agile practices, and align strategically with business goals.

Here are 30+ software engineering metrics that has been categorized into product, process and project metrics:

Product Metrics

1. Test and Code Coverage Percentage: Shows the extent to which the codebase is covered by automated tests, indicating test completion. Higher coverage improves confidence in code stability but doesn’t guarantee bug-free software.

2. Cyclomatic Complexity: Measures the number of independent paths through the code, helping assess its maintainability. Lower complexity often means simpler, easier-to-test code, while high values may signal refactoring needs.
3. Defect Leakage: Tracks bugs found post-release to identify gaps in testing or quality checks. A high leakage rate indicates issues in the testing lifecycle or requirements clarity.

4. Technical Debt: Calculates the long-term cost of quick fixes or sub-optimal code implementations and helps teams prioritize refactoring and maintainability to avoid future development slowdowns.
5. Pull Request Size: Monitors lines of code in a PR to manage review effort and reduce integration issues. Smaller, focused PRs are easier to review, test, and merge with fewer conflicts.
6. Response Time: Measures the time taken by the application to respond to a user’s action. It has a direct impact on user experience as lower response times lead to higher satisfaction.
7. Throughput: Indicates the amount of work delivered in a given time, such as features or fixes. Useful for assessing team productivity and identifying process bottlenecks.
8. Automation Health: Evaluates the pass/fail rate of automated tests, showcasing the test suite stability. Frequent failures may highlight flaky tests or unstable environments needing attention.
9. Release Velocity: Tracks how frequently production releases occur, showing delivery pace. It encourages smaller, faster iterations that reduce risk and improve feedback cycles.
10. Error Rate: Monitors the frequency of errors encountered in production environments in multiple phases. A high error rate can indicate system instability, poor testing, or scaling issues.
11. Net Promoter Score (NPS): Net Promoter Score is a leading indicator of product-market fit and overall user happiness. It captures customer loyalty and satisfaction by measuring willingness to recommend.
12. User Engagement: Measures how often and how deeply users interact with your software or features. High engagement often correlates with usability, value delivery, and retention success.

Process Metrics

13. Lead Time for Changes: Measures how often and how deeply users interact with your software or features.  A shorter lead time means faster feedback loops and quicker customer value delivery.
14. Deployment Frequency: Tracks how often code is pushed to production, reflecting team agility and DevOps maturity.  High frequency often indicates robust automation and a stable CI/CD pipeline.
15. Rework: Identifies how much code is rewritten shortly after delivery, often signaling quality issues or unclear requirements.   Frequent rework may highlight misalignment between design, development, and testing phases.
16. Commit Complexity: Analyze the difficulties of a code commit to predict potential risk or review effort required.   Complex commits tend to introduce more bugs and require more thorough reviews.
17. Development Velocity: Monitors the volume of work completed in a sprint, usually measured in story points or tasks.   This helps assess if the team is maintaining a steady and predictable delivery pace.
18. Scope Completion Ratio: Compares planned work at the start of a sprint versus what was actually delivered.   Low ratios may indicate over-commitment, technical blockers, or team capacity issues.
19. Scope Added After Sprint Start: Measures the amount of unplanned work added mid-sprint, helping flag scope creep.  Frequent mid-sprint changes can disrupt flow and reduce sprint focus and stability.
20. Cycle Time and Lead Time: Cycle time measures from work start to finish, while lead time includes wait time from request to delivery.   Monitoring both helps identify delays and streamline the development pipeline.
21. Change Failure Rate: Calculates the percentage of deployments that result in failures or require fixes.  A lower rate signifies better pre-release testing and stronger release readiness.
22. Mean Time to Repair (MTTR): Tracks how long it takes to recover from failures, impacting system resilience.  Faster recovery minimizes downtime and helps maintain user trust.
23. Responsiveness: Indicates how quickly the team responds to pull requests, bugs, or internal requests.   Quick responses improve collaboration and reduce wait time for contributors.
24. PR Iteration Time: Shows how many rounds of review a pull request undergoes before merging.   More iterations may reflect complex code, unclear goals, or low initial quality.
25. Thoroughly Reviewed PRs: Tracks the percentage of pull requests that go through complete and detailed peer reviews. Consistent reviews contribute to higher code quality and team knowledge sharing.
