Needs more than a quick edit5 of 10 checks passed
A PM would need to verify the weekly-active metric definition and add explicit conditions that would change the conclusion before posting; that is more than a quick edit.

Why I don't think the nav is the main cause
Mobile didn't change and still fell 5.2%. Web fell 6.3%. So about 5 points hit everyone, and the nav can explain at most about 1 point on web.1 Seasonality likely covers most of the shared drop. The same week last year we fell 4% as the school year started. The SSO outage (Thursday, 2 hours, about 30% of teams) is probably minor. A team only needs one session in the week to count as active.2 I'll confirm by comparing SSO and non-SSO teams. Beta teams fell only 1.1%. That looks reassuring, but beta teams may be more engaged than average, so I'm not relying on it.
Where the nav is hurting Navigation tickets rose from 40 to 212, and most are "where did X go?" That's friction now and a churn risk if we leave it.
Next steps, by Wednesday
Split the drop by SSO vs non-SSO teams, and beta vs comparable non-beta teams. Ship quick fixes for the most-asked "where did X go" items. Watch this week's number. If the drop is seasonal, it should flatten.
What a PM had to fix
1Numbers wrongRedo the arithmeticTargeted repair
Source: Metrics
Web only: −6.3%. Mobile only: −5.2%.
What we’d changeDon't cap the navigation's effect at 1 point: web and mobile differ in more than the navigation, so the subtraction doesn't hold. Give seasonality less credit, and hold the SSO reasoning until the split is done.
2Invented evidenceVerify or remove the claimQuick edit
What we’d changeThe brief doesn't define an active team. Present it as an assumption to check, since the SSO argument depends on it.

Got wrong · 3
- Uses the supplied evidence correctlyIt introduces an unsupported definition that a weekly active team only needs one session, which is not in the supplied context and does not follow by arithmetic.
- Avoids unsupported claimsIt presents the one-session active-definition claim as an established fact with no support.
- Owns the problemIt reports problems but does not state what the team has already done about them before recommending next steps.

- Addresses the actual decisionIt commits early that the nav is not the main cause but never states what result or condition would overturn that call.The two graders disagreed on this one.
- Identifies material uncertaintyIt names unknowns and says how to investigate but does not specify what outcomes would change the decision.The two graders disagreed on this one.
