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.

• 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.

• Respects explicit constraintsThe reply is under 200 words and addressed as a channel reply to Lena.
• Produces the required deliverableThe deliverable is a complete, usable channel reply within length.
• Answers the question askedThe first lines answer that the navigation is not the main cause.
• Separates effect from explanationCauses are labelled with uncertainty and paired with supporting or contradicting evidence.
• Ready for the reader as deliveredWritten for Lena with no unclear placeholders or lifted internal wording.

Claims the judge couldn’t find in the brief

• A team only needs one session in the week to count as active.

   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.

• Owns the problemIt owns the problem and recommends next steps, but does not state what the team has already done about the drop or ticket spike, and the recommendations lack explicit trade-offs.

• Uses the supplied evidence correctlyAll stated facts and figures come directly from the supplied context or follow by arithmetic, with no invented current-situation claims.
• Addresses the actual decisionIt commits clearly to 'navigation may be contributing but we don't yet know how much' and says evidence of navigation blocking core work would change the rollback decision.
• Respects explicit constraintsIt is addressed to Lena, written as a channel reply, and is 189 words, under the 200-word limit.
• Identifies material uncertaintyIt names the key unknowns—navigation contribution, broader factor, seasonality, SSO impact, beta selection—and says daily activity split by platform, SSO and beta will resolve them.
• Avoids unsupported claimsHypotheses are labelled with 'may,' 'likely,' 'plausible,' 'candidate,' and 'could,' and no unlabelled cause is asserted as fact.
• Produces the required deliverableThe requested reply is present and complete, under the word limit, and usable by Lena as a channel update.
• Answers the question askedThe first lines directly answer whether the new navigation caused the drop by saying it may be contributing but the amount is not yet known.
• Separates effect from explanationNavigation, seasonality, SSO outage, and beta learnings are each treated as possible explanations with their supporting or contradicting evidence.
• Ready for the reader as deliveredIt is written entirely for Lena with no unexplained brief terms, placeholders, or invented owners or dates.
