Why UK product teams under-instrument onboarding
Onboarding is where App Analytics should be richest and is often poorest. I have sat with product squads in Leeds, Glasgow, and a converted warehouse in Hackney who could tell me last week’s ROAS to two decimals and could not say what share of new users granted notification permission before the first successful task. The tour shipped. The events did not.
Part of this is politeness. A British product culture still treats the first session as hospitality: do not interrogate the guest. Instrumentation feels like interrogation. The result is a funnel that begins at “account created” and skips the messy rooms — ATT, camera permission, postcode lookup, the skip link on the education carousel.
The rooms that go dark
Permission prompts are the classic dark room. iOS in particular will not let you restage the drama. If you do not event the impression, the accept, and the deny as separate sentences, you will invent a story about “users who hate notifications” when you merely asked at a greedy moment. First-task success is the second dark room. Registration is not a task. Finding a train, scanning a receipt, or playing thirty seconds of the radio is a task.
A third darkness: skip. Teams instrument completion of the carousel and forget the skip control. Skip is not failure. It is a preference. Without it, your onboarding “conversion” is a mixture of the curious and the trapped.
A minimum set
For a United Kingdom consumer app we recommend five versioned events in week one of a new flow: onboarding_shown, permission_prompted (with type), permission_resolved, first_task_started, first_task_succeeded. Properties should name the app version and the experiment arm, not the user’s star sign. If legal colleagues worry about the permission event, show them that you are recording the system prompt outcome, not a private biography.
Why it keeps happening
Deadlines. The store listing wants screenshots. The designer wants a tour. The analyst arrives after the freeze. Funnel Forensics exists partly because of this sequence. If you are about to ship a new first session, write to the desk before the freeze, not after the retrospective. Event Grammar notes will get you further than a slide titled “onboarding best practices.”
Hospitality and measurement can share a room. You can still write a warm welcome screen. Just let the packets say whether anyone made it through the door.
