The following metrics are part of Quality -

#### [**Code Health**](https://typo.gitbook.io/typo-help-docs/engineering-metrics/code-quality-metrics)

Code health refers to the number of issues in your code, categorized into two main types: security and vulnerability.

#### [PRs Merged w/o Review](https://typo.gitbook.io/typo-help-docs/engineering-metrics/pull-request-metrics/prs-merged-without-review)

Pull Request merged without review refers to all those pull requests that are merged without the review being approved.

#### [**PR Size**](https://typo.gitbook.io/typo-help-docs/engineering-metrics/pull-request-metrics/pr-size)

The average number of lines of code added and deleted across all merged pull requests (PRs) within a specified time frame

#### [Avg. commits](https://typo.gitbook.io/typo-help-docs/engineering-metrics/pull-request-metrics/avg.-commits-during-pr-review)

This represents the average number of commits made to each Pull Request after it is raised for review. It is an indicative measure of the quality of code & code reviews.

#### [**Change Failure Rate**](https://typo.gitbook.io/typo-help-docs/engineering-metrics/dora/change-failure-rate)

CFR(Change Failure Rate) refers to the proportion or percentage of deployments that result in failure or errors, indicating the rate at which changes negatively impact the stability or functionality of the system.

#### [**Review Time**](https://typo.gitbook.io/typo-help-docs/engineering-metrics/pull-request-metrics/review-time)

The "Review" stage represents the average time taken to complete the code review of Pull Requests.
