Review participation answers one question: is code review spread across the team, or carried by two people? Leanmote has no single number for it — there is no participation percentage to look up. What it has is the data to answer the question in about thirty seconds.
Where to read it
Open the Team Activity table and add the Reviews column. Every member of the selected team gets a row, so "who participates in review?" becomes "how many of these rows are above zero?".
What counts as a review
A review is any of three actions on a pull request the person did not author:
a comment — each one counts separately, so ten comments on one pull request count as ten
a commit pushed to that pull request
the first approval on it, and only the first — later approvals are not counted
Pull requests you authored are skipped entirely, so nobody's own work inflates their count.
Two consequences worth holding onto. A talkative reviewer will outrank a thorough one, because comments are counted one by one. And somebody who only approves will show a far lower number than somebody who comments, even when they read the same amount of code.
How to interpret it
These are rules of thumb. Leanmote does not flag any of them.
Two or three rows above zero on a larger team means review is concentrated. Watch for senior burnout.
Most of the team above zero is healthy — participation without it being mandatory busywork.
Everybody at exactly one or two can mean rubber-stamp approvals rather than genuine engagement. Open the drill-down and look at the review type: all
Approvaland noCommentis the signature.
What to do about it
If participation is concentrated, distribute reviews via auto-assignment or a rotating reviewer rota.
Pair junior engineers with seniors so review skills spread.
Surface review activity in 1:1s — sometimes participation is invisible because nobody notices it.
