The Quality tab is the newest addition to the
[Metrics page](/resources/metrics-page). Where the other tabs measure
what your team ships and how fast, Quality measures how your team
reviews. All of it adjusts to the people, teams, and timeframes you
care about.

![The Quality tab of Mesmer's Metrics page, scoped to an 8-person team over the last 30 days. Five metric tiles run across the top — Quality per PR reviewed (82 out of 100), Time to first review (9h 59m), Rubber-stamp reviews (87%), Total effort reviewed (76,335), and Effort per PR reviewed (185) — each showing its change versus the previous period. Below, an 'Effort reviewed over time' bar chart with a 7-day average line, spanning late June to mid-July.](/blog/Quality_Metrics.png)

### What's new

- **Effort reviewed over time.** How much reviewed effort your team is
  absorbing, week over week, so review load reads as a trend instead of
  a guess.
- **Time to first review.** How long a pull request waits before anyone
  looks at it — the quiet delay that stretches cycle time before a
  single line of feedback is written.
- **Rubber-stamp reviews.** The share of reviews that approve without
  engaging: no comments, no changes requested, merged as-is.
- **Effort per PR reviewed.** How much effort sits behind the average
  PR under review, so a jump in review load reads as either more PRs or
  heavier ones.
- **Quality per PR reviewed.** The mean [PR Quality grade](/resources/pr-quality)
  across reviewed changes, so review depth and review outcome sit on the
  same screen.
