Lead Time and Change Velocity
I've dealt with my fair share of lead time issues throughout my career. It usually starts the same way: a quick refinement that underestimates the work or misses critical dependencies.
Then we got stuck in the middle of the sprint, wondering which tasks will slip to the next sprint. The number of factors that can cause delays is staggering: unclear requirements, slow code reviews, understaffed DevOps teams, or simply too many meetings.
There's no silver bullet for fixing lead time, but tracking it over time helps identify bottlenecks and evaluate whether process changes actually make a difference. That’s why lead time became a core metric in the DORA framework.
Why it matters
Velocity shows how fast your team ships code and lead time measures how long it takes from starting work to getting it merged. When velocity drops, something is slowing your team down. When the lead time is long, work sits waiting instead of moving forward. Fast velocity with short lead time means your team is productive and your process works well.
Cosmic Analogy
Velocity shows how strong the rocket engines are once they're firing. Small flames mean drag from things like extra checks, coordination overhead, or clutter slowing the ship down.
Lead time shows the full journey from Earth to docking: the drifting astronaut and asteroids represent waiting and bottlenecks along the way. A short, glowing path means a smooth flight with few delays. In simple terms, velocity is how fast you fly, while lead time is how long it takes to reach orbit and dock.

How to Fix
Code Review & PR Management
- Set SLAs for code reviews to prevent PRs from stuck for days without feedback.
- Break large features into smaller PRs to reduce review time and accelerate merge cycles.
Process & Workflow Optimization
- Identify and remove process bottlenecks. Analyze where work sits idle (reviews, deployments, testing).
- Implement work-in-progress limits to prevent too many parallel tasks that extend the lead time.
- Improve requirement clarity upfront to avoid mid-sprint surprises and delays.
Automation & Infrastructure
- Automate testing and deployment pipelines to eliminate manual delays and wait times.
- Address technical debt in areas that slow down development and extend lead times.
Developer Productivity
- Reduce context switching and meeting overhead that kills developer productivity and velocity.
Measurement & Monitoring
- Track lead time by feature type (bug fix vs. feature) to understand where delays concentrate.
- Monitor trends over time to validate whether process improvements actually reduce lead time and increase velocity.
