Approval gate

What the measure captures

An approval gate is a workflow checkpoint that prevents a change from advancing until a defined reviewer decision is recorded. It is most useful when the team states the unit of analysis, the start event, the completion event, and the population being measured. A review request, a pull request, and a merge are related events, but they are not interchangeable. Keeping those boundaries visible prevents a dashboard from turning an operational signal into an unexplained score.

A practical example

A release branch may use an approval gate after automated checks and before merge, with the responsible team documented in repository settings. Start with a small sample and inspect the underlying requests before creating a target. Record the repository, change type, reviewer path, and relevant policy state. That makes it possible to explain an unusual result instead of simply celebrating or escalating a number. Compare similar work over time and annotate major changes in ownership, branch rules, or automation.

How to use it carefully

A gate confirms process state, not software quality. Pair it with tests, evidence, and review notes that explain the decision. Review metrics work best as prompts for team-level investigation. Combine them with review samples, author and reviewer feedback, escaped defects, rework, and delivery outcomes. Avoid ranking individuals from a single measure because review difficulty, system familiarity, and assignment patterns vary. A healthy process makes useful feedback available at an appropriate time while preserving accountability for the final change.

How this relates to Weave

Weave can connect review events with change context and delivery signals so teams can inspect approval gate alongside review time, pull request size, and flow. That context helps teams investigate queues and quality patterns without treating one review number as a verdict on an engineer.
