How it’s graded

Each check is built on how world-class product and growth leaders do this work, as they’ve described it on Lenny’s Podcast, and names the leader it comes from.

Limits the downside of being wrong
Does the call say how exposure is limited if it's wrong: what is watched after launch, the threshold that would pause or roll back, and which parts can't be undone?
Passes when Names the post-launch signal, a threshold or trigger, and the action, and flags anything irreversible (customer communications, pricing, migrations).
Karri SaarinenLenny’s Podcast
Judges the launch against a baseline set now
Does the call name the metric and the current baseline the launch will be judged against, and when the team will review the result to decide what's next?
Passes when Names the success metric, its baseline from the material, and a review point with what each result would lead to.

# Incidents during the 25% rollout (14 days)

- 2 reports of a note's edits being overwritten after a conflict, both on Android 11; engineering recovered both from backups. Root cause: an older Android storage API.
- 1 report of slow sync on iOS, not reproduced.

The launch review is Friday: roll offline sync out to 100%, or not. Marketing has a launch email booked for Monday to every user.

What a strong answer doesThe answer key the graders mark against

Checks each criterion per platform. iOS 17+, Android 14+ and Android 13 pass: crash-free sessions within 0.2 points of control (iOS -0.04, Android 14+ -0.06, Android 13 -0.09), sync-conflict tickets under 2 per 1,000, notes synced without error at least 99%. Android 12 and older fails three criteria: crash-free down 0.67 points against control, 4.9 conflict tickets per 1,000, 96.1% synced without error; and the two overwritten-note incidents were on Android 11, which breaks 'no data loss' (both recovered from backup, root cause an older storage API). Recommends go for iOS, Android 13 and newer, and no-go for Android 12 and older until the storage issue is fixed and re-tested; the Monday email should only go to users on supported versions, or wait. States what's monitored after launch and the threshold that would pause it.

Output

To: Launch Review Committee From: Product Manager, Mobile Apps Date: Friday (Launch Review) Subject: Offline Sync 100% Rollout Recommendation

Executive Recommendation: Go with Conditions (Segmented Rollout)

Based on our 14-day, 25% rollout data, I recommend a Go for iOS 17+ and Android 14+, which represent 80.5% of our mobile user base.

I recommend a No-Go for Android 12 and older due to severe stability and data loss issues, and a Go with Conditions (or short delay) for Android 13, which narrowly missed our sync error threshold by 0.1%.

Consequently, Marketing must not send the Monday launch email to every user. We must either segment the email to eligible OS versions or adjust the messaging to reflect system requirements (iOS 17+ / Android 14+).

Detailed Rationale & Next Steps

1. Greenlight iOS 17+ and Android 14+ (Roll out to 100% on Monday) Both modern platforms passed every gate with healthy margins. The single report of slow sync on iOS could not be reproduced and did not impact overall sync success rates (99.4%). These cohorts are ready for a 100% rollout.

2. Block & Roll Back Android 12 and Older (Immediate Action) Android 12 and older failed all four launch criteria. Most critically, an older Android storage API caused two incidents on Android 11 where conflict resolution overwrote user edits (requiring manual backup recovery by engineering). For a collaborative notes app, data loss is a dealbreaker. * Action: Immediately roll back the 25% test cohort on Android ≤12 to 0%. Engineering will scope whether fixing the legacy storage API is worth the investment for 9.5% of our base, or if we officially deprecate offline sync for Android ≤12.

3. Android 13 Conditions Android 13 passed stability, conflict ticket, and zero-data-loss criteria, but hit 98.9% on error-free syncs (0.1 points short of our 99.0% gate). * Condition for Go: If Engineering confirms before EOD today that Android 13 does not use the legacy storage API that caused the Android 11 data loss, and that the 1.1% error rate fails gracefully (i.e., retries on next connection without corrupting data), we can include Android 13 in Monday’s launch while fast-following a patch. * Alternative: If there is any architectural overlap with the Android 11 bug, hold Android 13 at 25% until patched.

4. Marketing & Monday Email Plan Because we are holding back at least 9.5% (and up to 21.2%) of users on older Android versions, we cannot send a blanket announcement to all users without generating support tickets and frustration. Marketing has two options for Monday: * Option A (Recommended): Segment the email list to send only to users on iOS 17+ and Android 14+ (and Android 13, if cleared today), plus Web users. * Option B: Send to all users, but explicitly state in the email body and help docs: "Offline sync is rolling out today for iOS 17+ and Android 14+."

Claims the judge couldn’t find in the brief

iOS 17+ and Android 14+ represent 80.5% of our mobile user base.

Output

Recommendation for Friday

No-go for a blanket 100% launch. Approve a platform-gated launch for iOS 17+ and Android 14+, provided eligibility can be enforced reliably. Hold Android 13, stop expansion on Android 12 and older, and do not launch on untested platforms.

Replace Monday’s all-user email with a targeted announcement to eligible users only. If targeting or platform gating cannot be verified before send time, postpone the email.

Launch-criteria assessment

Crash-free changes below are percentage-point differences versus each platform’s control. The agreed limit is a decline of no more than 0.20 points.

Platform	Crash-free sessions	Conflict tickets: <2/1,000	Notes synced without error: ≥99%	No data loss incidents	Platform decision
iOS 17+	Go: 99.58%; −0.04 points	Go: 0.6	Go: 99.4%	Go: none reported	Go with conditions: passes all measured criteria; launch with eligibility gating and monitoring.
Android 14+	Go: 99.49%; −0.06 points	Go: 0.8	Go: 99.2%	Go: none reported	Go with conditions: passes all measured criteria; launch with eligibility gating and monitoring.
Android 13	Go: 99.31%; −0.09 points	Go: 1.1	No-go: 98.9%, below the 99% minimum	Go: none reported	No-go: sync reliability misses the agreed threshold.
Android 12 and older	No-go: 98.71%; −0.67 points	No-go: 4.9	No-go: 96.1%	No-go: two overwrite incidents on Android 11	No-go: fails all four criteria.
Web / iOS below 17, if supported	No-go: no evidence supplied	No-go: no evidence supplied	No-go: no evidence supplied	No-go: not established by supplied evidence	No-go pending validation: absence of rollout data is not a pass.

The recovered Android 11 edits still count as data-loss incidents for this launch gate: users’ edits were overwritten, and recovery required backups. Recovery mitigated the harm; it does not erase the incidents. Nor should Android 11’s identified root cause be used to clear the rest of the “Android 12 and older” cohort without separate evidence.

Conditions and next steps

Before expanding eligible cohorts: Engineering must verify OS-level gating, rollback controls, and platform-specific monitoring. Increase exposure in monitored steps toward 100% of eligible users, pausing if a launch criterion is breached. Investigate the unreproduced iOS slow-sync report; it is not currently evidence of a failed criterion.
Android 13: Diagnose the sync-error shortfall, ship a fix, and repeat validation against the same ≥99% threshold. Do not round 98.9% up or waive the criterion to meet the email date.
Android 12 and older: Halt expansion and safely disable affected functionality where feasible, preserving pending offline edits before any rollback. Fix the older-storage-API issue, test conflict recovery and data integrity, and rerun a controlled rollout demonstrating all four criteria.
Marketing and support: Clearly state supported versions and avoid implying universal availability. Give support a recovery and escalation playbook.

These results cover 14 days at 25% exposure, not proof of risk-free operation at full scale. The defensible decision is a constrained launch where the evidence passes—not a universal launch driven by Monday’s booking.

Recommendation: offline sync to iOS 17+ and Android 14+ only

Don't roll out to 100% globally on Friday. Roll it out to iOS 17+ and Android 14+, hold Android 13, and turn it off for Android 12 and older. Marketing's Monday email should go only to the users who get the feature.

Platform	1. Crash-free (≤0.2 below control)	2. Conflict tickets (<2 per 1,000)	3. Notes synced without error (≥99%)	4. No data loss	Decision and why
iOS 17+	Go: 99.58 vs 99.62 (−0.04)	Go: 0.6 (control 0.3)	Go: 99.4 (control 99.5)	Go: no data-loss reports	Go. Passes all four. The one slow-sync report wasn't reproduced, so I'd watch it but it doesn't block launch.
Android 14+	Go: 99.49 vs 99.55 (−0.06)	Go: 0.8 (control 0.3)	Go: 99.2 (control 99.5)	Go: none logged	Go with conditions. Passes all four, but conflicts are 2.7× control and sync errors are slightly worse. Conditions below.
Android 13	Go: 99.31 vs 99.40 (−0.09)	Go: 1.1 (control 0.3)	No-go: 98.9, below 99%	Go: none logged	No-go. Fails the sync-error criterion. Reopen when it reaches 99% in a new test.
Android 12 and older	No-go: 98.71 vs 99.38 (−0.67)	No-go: 4.9 (control 0.3)	No-go: 96.1	No-go: two overwritten-edit incidents on Android 11	No-go. Fails all four criteria. The data-loss incidents are the decisive problem.

Web isn't in the 25% rollout data, so there's no evidence it meets any criterion. It's a no-go until it's tested.

On the data-loss criterion: the two Android 11 incidents count as failures even though engineering recovered the edits from backups. The criterion is "no data loss incidents," not "no unrecoverable data loss." Their root cause is an older Android storage API, which suggests the problem is specific to older devices. The Android 12-and-older segment also fails the crash and conflict criteria by a wide margin, so the storage fix alone doesn't justify launching there.

Why not a global launch

A global launch would put Android 12-and-older and Android 13 users on a feature that fails the agreed criteria. That segment already shows about 36 conflict tickets per 1,000 treated users... no, 4.9 per 1,000, almost 16 times control, and a 0.67-point crash-free drop. Data loss is the most serious harm a notes app can cause, and users who lose work are unlikely to forgive it.

We agreed these criteria before the rollout. Passing three of four on the platforms that matter most is not enough to waive the fourth, and waiving it now would set a bad precedent.

Before Friday

1. Engineering: Confirm the Android 11 storage fix and check that no other users had edits overwritten. Verify the backup recovery was complete. 2. Feature flag: Build a server-side switch that disables offline sync for Android 13 and below. Before disabling it on a device, flush any pending offline edits. Otherwise a user could lose changes made offline during the switch-off. 3. Monitoring: Set daily alerts with rollback triggers. Roll back any enabled platform if any of these happen: - Any data-loss report - Crash-free sessions more than 0.2 below control - Conflict tickets at or above 2 per 1,000 - Android 14+ conflicts above 1.5 per 1,000 (an early warning, since it's already at 0.8)

Monday's email

Don't send it to every user. Send it only to iOS 17+ and Android 14+ users, and only after the feature is live for them. The email should not promise offline editing on web or on older Android versions. If marketing can't segment the list in time, move the email back a week. A broad email would drive users on unsupported platforms to a feature that is currently losing their notes.

Summary

Launch Friday: iOS 17+ (go), Android 14+ (go with conditions)
Hold: Android 13 (no-go until sync errors reach 99%)
Turn off now: Android 12 and older (no-go)
Web: no-go until tested
Email: segmented to launched platforms only

The PM job

Deciding whether a feature ships on the planned date, and on what conditions.

Why it matters

Launch meetings reward optimism. A good call checks each agreed criterion, weighs a real risk against a real gain, and says exactly what would change the answer. A weak one rubber-stamps the launch or blocks it on noise.
