The complete developer productivity glossary
The essential reference for engineering leaders and teams.

Taylor Bruneaux
Analyst
Engineering leaders are talking more about developer productivity than ever before. But we’re not always talking about the same things.
Teams debate whether “cognitive load” is measurable. Product managers ask about “velocity” while engineering managers focus on “cycle time.” Platform teams discuss “golden paths” as if everyone knows what that means.
This isn’t just semantics. When we use different definitions, we make poor decisions. When we conflate related metrics, we miss what’s actually happening.
We started collecting these terms for our own discussions, then expanded as we talked with more organizations. What began as a few definitions grew into something comprehensive.
This glossary captures the language of developer productivity—from AI coding tools to platform engineering, from DORA metrics to cognitive complexity. Each definition includes context about why it matters and how it connects to broader goals.
The better we understand these concepts, the clearer our conversations about what we’re measuring and building.

Cycle time
The time from when work begins on a feature or task until it’s delivered to users. Cycle time measures the efficiency of the entire development process and helps identify bottlenecks in delivery.
Cyclomatic complexity
A software metric that measures the number of linearly independent paths through a program’s source code. Cyclomatic complexity has limitations in understanding overall code quality but provides useful insights into code complexity.
Defect density
The number of defects found per unit of code, typically measured as defects per thousand lines of code. Defect density helps compare quality across different modules or time periods.
Defect leakage
The percentage of defects that escape into production rather than being caught during development or testing phases. Lower defect leakage indicates more effective quality assurance processes.
Developer experience index (DXI)
A composite metric from DX that measures the overall quality of the developer experience, combining factors like tool efficiency, documentation quality, and development process satisfaction. DXI helps organizations prioritize developer experience improvements.
Developer satisfaction
Measurements of how satisfied developers are with their work environment, tools, processes, and organizational culture. Developer satisfaction correlates with retention, productivity, and code quality.
DevOps metrics
Key performance indicators used to measure the effectiveness of DevOps practices, including deployment frequency, failure rates, and recovery times. DevOps metrics and KPIs should drive actual improvement rather than just measurement for its own sake.
DORA metrics
The four key metrics from the DevOps Research and Assessment team: deployment frequency, lead time for changes, change failure rate, and time to restore service. DORA metrics are widely used to assess software delivery performance.
Engineering efficiency
Measures of how effectively engineering teams convert effort into valuable outcomes, considering factors like velocity, quality, and resource utilization. Engineering efficiency helps optimize team performance and resource allocation.
Engineering KPIs
Key Performance Indicators specific to engineering teams, including metrics like deployment frequency, code quality, developer satisfaction, and delivery predictability. Engineering KPIs align technical work with business objectives.
Escaped defects
Bugs or issues that were not caught during development or testing phases and were discovered in production. Tracking escaped defects helps improve quality assurance processes and prevent similar issues.
Flow distribution
The allocation of development effort across different types of work, such as new features, bug fixes, technical debt, and maintenance. Understanding flow distribution helps balance competing priorities and optimize value delivery.
Flow efficiency
The ratio of active work time to total cycle time, indicating how much time work items spend being actively worked on versus waiting. Higher flow efficiency suggests fewer bottlenecks and smoother processes.
Flow load

Flow metrics
A set of measurements that track the movement of work through development processes, including flow velocity, flow time, flow load, and flow efficiency. Flow metrics help optimize development workflows and identify improvement opportunities.
Flow time
The total time from when work on an item begins until it’s completed and delivered. Flow time encompasses all phases of development and helps identify the longest steps in the delivery process.
Lead time for bug fixes
The time from when a bug is reported until the fix is deployed to production. Shorter lead times for bug fixes improve user experience and reduce the impact of issues.
Lead time for changes
The time from when code is committed until it’s successfully running in production. This DORA metric measures the efficiency of the entire software delivery pipeline.
Lines of code
A basic metric counting the number of lines in a codebase or contribution. While easy to measure, lines of code is a poor indicator of productivity or value, as quality and complexity matter more than quantity.
Mean time to recovery (MTTR)
The average time required to restore service after an incident or failure. Lower MTTR indicates better incident response capabilities and system resilience.
PR size
The amount of code changes in a pull request, typically measured in lines added, modified, or deleted. Smaller PRs are generally easier to review, test, and merge safely.
Pull request count
The number of pull requests created over a specific time period. PR count can indicate development activity but should be considered alongside other metrics like PR size and review quality.
Pull request throughput
The rate at which pull requests are completed and merged, measuring the efficiency of the code review and integration process. Higher throughput indicates smoother development workflows.
Review-to-commit ratio
The ratio of code reviews performed to commits made, indicating whether developers are contributing fairly to code review activities. Balanced ratios help distribute review workload and maintain code quality.
Sprint velocity
The amount of work completed by a team during a sprint, usually measured in story points or completed tasks. Sprint velocity helps teams plan future work and track performance trends over time.
Story points
A relative estimation unit used in agile development to measure the effort, complexity, and risk involved in completing user stories. Story points help teams plan capacity and track velocity without focusing on time estimates.
Task completion rate
The percentage of planned tasks or user stories completed within a given time period. Task completion rate indicates team productivity and the accuracy of planning and estimation processes.
Test coverage
The percentage of code that is executed by automated tests, indicating how thoroughly the application is tested. Higher test coverage generally correlates with fewer bugs and more confident deployments.
Test failure rate
The percentage of test runs that fail, indicating potential issues in code quality or test reliability. High test failure rates can slow development and may indicate problems with tests or code.
Test pass rate
The percentage of tests that pass successfully during automated test runs. Consistently high test pass rates indicate stable code and reliable testing processes.
Throughput
The amount of work completed per unit of time, such as features delivered per sprint or stories completed per week. Throughput measures team productivity and helps with capacity planning.
Time to merge
The duration from when a pull request is created until it’s merged into the main branch. Shorter merge times indicate efficient review processes and reduce the risk of merge conflicts.
Time to restore service
The time required to recover from a failure or incident, measuring how quickly teams can restore normal operations. This DORA metric indicates the effectiveness of incident response and system resilience.
Waiting time
The time work items spend idle between active work phases, such as waiting for code review, testing, or deployment. Reducing waiting time improves overall flow efficiency and delivery speed.
Work in progress (WIP)
The amount of work that has been started but not yet completed. Managing WIP through limits helps teams focus, reduce context switching, and improve flow efficiency.
