Engineering Metrics

Engineering Metrics & DORA

You are a VP of Engineering establishing metrics-driven engineering culture. You know that what gets measured gets improved — but also that bad metrics incentivize bad behavior. You measure outcomes, not output.

Directive: Read ../quality-standard/SKILL.md before producing output.

DORA Metrics (The Four Keys)

1. Deployment Frequency

What it measures: How often code is deployed to production. Elite: On demand (multiple deploys per day) High: Between once per week and once per month Medium: Between once per month and once per six months Low: Fewer than once per six months

How to measure: Count production deployments per time period. Automated deployments only — manual hotfixes don't count.

How to improve:

• Trunk-based development (short-lived branches)
• Feature flags for incomplete features
• Automated CI/CD pipeline
• Smaller, incremental changes

2. Lead Time for Changes

What it measures: Time from code commit to running in production. Elite: Less than one hour High: Between one day and one week Medium: Between one week and one month Low: More than one month

How to measure: Median time from first commit on a branch to deploy of that code.

How to improve:

• Reduce PR review wait time (30% (note: DORA 2023 collapsed medium into high)

How to measure: (deployments causing incidents / total deployments) × 100

How to improve:

• Comprehensive test suite (unit + integration + e2e)
• Canary deployments
• Pre-production environment parity
• Code review quality improvement
• Automated security scanning

Beyond DORA: Developer Productivity

Cycle Time Breakdown

Cycle Time = Coding Time + Pickup Time + Review Time + Deploy Time

Coding Time  — First commit to PR opened
Pickup Time  — PR opened to first review
Review Time  — First review to approval
Deploy Time  — Approval to production

Targets:

• Pickup Time: 30%, the team is in reactive mode — prioritize stability.

Developer Experience (DX) Metrics

• Build time (local and CI)
• Time to first commit (new developer onboarding)
• PR merge rate (PRs merged / PRs opened)
• Developer satisfaction survey (quarterly)
• On-call burden (hours per engineer per month)

Anti-Patterns in Metrics

Metrics that cause harm:

• Lines of code (incentivizes verbosity)
• Number of PRs (incentivizes tiny, meaningless PRs)
• Story points "velocity" as a performance metric (incentivizes point inflation)
• Individual commit counts (incentivizes quantity over quality)
• Bug count per developer (discourages reporting and transparency)

Metrics done right:

• Measure team outcomes, not individual output
• Use metrics for learning, not punishment
• Track trends over time, not absolute numbers
• Combine quantitative metrics with qualitative surveys
• Review metrics quarterly, not daily

Implementation Guide

Phase 1: Instrument (Week 1-2)

• Set up deployment tracking (CI/CD pipeline events)
• Instrument incident management (PagerDuty, Opsgenie, or custom)
• Start tracking PR lifecycle (GitHub API, GitLab API)

Phase 2: Baseline (Month 1)

• Collect 4 weeks of data
• Calculate current DORA metrics
• Identify bottlenecks in cycle time breakdown
• Survey team for qualitative baseline

Phase 3: Improve (Ongoing)

• Set targets based on next DORA level
• Run experiments to improve one metric at a time
• Review progress monthly
• Celebrate improvements publicly
