Ticket Terms
Backlog
time span from ticket creation to an assignment to a contributor
Pickup
time spans from assignment to a contributor until its status changes to an in-progress stage
Resolution
time span from being in-progress until being marked as resolved/done etc.
Lead Time
Lifecycle of a ticket from creation to being done
Throughput
Number of items processed in time. E.g. number of tickets closed.
Velocity
Same as throughput. Often used in VSM/Flow frameworks.
Capacity
Throughput in achieving a goal, e.g., number of tickets successfully resolved in a sprint. Sustained achievable outcomes.
Overloaded
Beyond a pre-defined capacity. For instance a contributor has more than a certain healthy number of tasks assigned.
Sprint Overrun
Defined per ticket. A ticket overruns a sprint if it is not resolved in the initially assigned sprint.
Unplanned Work
Defined per ticket. A ticket is unplanned if it is added to a sprint after the initial sprint start date.
Slow Response
Defined per ticket. A ticket that has been assigned but has not been moved to in-progress for more than a pre-defined time.
Unassigned WIP
Defined per ticket. A ticket that has been moved to a work-in-progress (WIP) state, but is not assigned to anyone
Long Running WIP
Defined per ticket. A ticket that has been moved to an in-progress state, but has not been closed in a pre-defined time.
Code & Pull Request (PR) Terms
Development
time from first commit to opening the PR
Response
time from opening the PR to start of a review
Review
time from first review response to approval of the PR
Integration
time from approval of the PR until its merge/closure
Cycle Time
Lifecycle of a PR from creation to being merged/closed.
Throughput
Number of items processed in time. E.g.: number of PRs merged.
Velocity
Same as throughput. Often used in VSM/Flow frameworks.
Capacity
Throughput in achieving a goal, e.g., number of PRs reviewed in a sprint. Sustained achievable outcomes.
Overloaded
Beyond a pre-defined capacity. For instance a contributor has more than a certain healthy number of PRs open in parallel.
Non-Productive Work
Defined per PR. A PR that has been opened but does not make it into the product, i.e., gets closed or abandoned without merging.
Merged Outside Process
Defined per PR. A PR is merged without being reviewed or approved.
Stale
Defined per PR. A PR has been opened but did not progress from one stage to another in a pre-defined time.
Long Running WIP
Defined per PR. A PR that has been opened but not merged in a pre-defined time.
Risky Change
A pull request flagged for extra attention because it is unusually large or far-reaching — for example, changing a high number of lines, spanning many commits, or touching many files.
Complex Review
A pull request flagged for extra attention because its review involved unusually high effort — for example, a high volume of review comments, multiple review cycles, or several active reviewers.
New Work
New code being committed that does not change existing code.
Rework Own
Changes a developer makes to recently written code that they originally authored.
Rework Others
Changes a developer makes to recently written code that was originally authored by someone else.
Maintenance code
Changes to older, established code rather than recently written code.
DORA Terms
Deployment Frequency
How often a team successfully deploys to production. Higher frequency indicates smaller, more manageable changes.
Lead Time for Changes
Time from code committed to code running in production. Measures the efficiency of the delivery pipeline.
Change Failure Rate
Percentage of deployments that require immediate intervention (rollbacks or hotfixes). Measures deployment quality.
Failed Deployment Recovery Time
Time from a deployment-caused failure to service restoration. Formerly called Mean Time to Recovery (MTTR). Renamed in 2023 to scope specifically to deployment failures.
Deployment Rework Rate
Percentage of deployments that are unplanned fixes for production issues. Introduced as the 5th DORA metric in 2024.
