Case viewer

Read the brief, then put up to three outputs side by side, each with the LLM judge’s verdict on every check. Highlights mark what a PM had to fix.

The brief

Our CEO, Lena, posted in the leadership channel: “Why did weekly active teams drop 6% last week? Is it the new navigation?” You own the product area. Using the material below, write your reply to Lena, to post in the channel. Keep it under 200 words.

ScenarioTrellis is a project-management tool for small teams. The new navigation went to 100% of web users on Tuesday 15 September after two weeks in a 10% beta. The mobile apps did not change.
MetricsWeekly active teams: week of 7 September 18,420; week of 14 September 17,310 (−6.0%). Web only: −6.3%. Mobile only: −5.2%. Teams that were in the navigation beta: −1.1%. The same week last year, weekly active teams fell 4%, which we put down to the start of the school year.
IncidentOn Thursday 17 September, single sign-on failed for two hours. About 30% of teams use single sign-on.
SupportTickets mentioning navigation: 212 last week, up from 40. Most are some version of “where did X go?”
What a strong answer does

Answers directly that the cause is not established and the navigation is unlikely to be the main driver (mobile, which did not change, fell nearly as much, and the beta cohort barely moved), while taking the navigation support tickets seriously. Names the other candidates with their evidence (seasonality, the SSO outage), says what is being checked and when Lena will hear back.

Usable with a quick edit9 of 10 checks passed

The evidence and reasoning are sound and the reply is post-ready. A quick edit could add already-taken actions or trade-offs, but no evidence re-check or rework is needed.

Output

Lena, we lost 1,110 weekly active teams. Navigation may be contributing, but we don’t yet know how much.1 I own investigating this and the response.

Mobile-only teams also fell 5.2%, despite no navigation change, so there’s likely a broader factor. Last year’s 4% dip makes seasonality plausible, but doesn’t establish this year’s cause. Thursday’s two-hour SSO outage is another candidate; 30% of teams use SSO, but that doesn’t tell us how many missed the entire week.

Navigation tickets rose from 40 to 212, mostly “where did X go?” That’s clear friction we should address now, though it doesn’t establish the cause of the activity drop. Beta teams fell just 1.1%; familiarity could help, but they may differ from other teams.

I’ll report back tomorrow with daily activity around Tuesday’s rollout and Thursday’s outage, split by platform, SSO use and beta status, checking tracking and prior trends. I’ll also check whether affected teams returned later in the week and where key workflows deteriorated.

Meanwhile, we’ll prioritise the missing destinations behind those tickets. I wouldn’t roll back solely on this aggregate result; evidence of navigation blocking core work would change that.

What a PM had to fix

  1. 1Decision deferredMake the callQuick edit

    Source: MetricsMobile only: −5.2%.

    What we’d changeAnswer Lena's question more directly: mobile's 5.2% drop with no navigation change points away from the navigation as the main cause. Tighten the SSO hedge.

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.

Output

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

  1. 1Numbers wrongRedo the arithmeticTargeted repair

    Source: MetricsWeb 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.

  2. 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.

About the task

The PM job

Writing the weekly update, or the reply to an executive's question, that the team's credibility rests on.

Why it matters

Updates are where bad news gets softened. A fluent update that buries a slipped date or presents a guess as the cause does more harm than no update: leadership decides on it, and trust goes when the truth comes out.

What good looks like

  • Leads with the news and any decision needed
  • States dates, numbers and causes plainly, including bad news
  • Separates what is known from what is suspected
  • Brings a recommendation and what's been tried, not just the problem
  • Fits the reader and the length asked for

Deliberately not measured

  • Tone and formatting preferences
  • Writing style beyond clarity
Capability tested

Honest, decision-first status communication
