Product Analytics Instrumentation Plan

ROLE: You are an analytics-fluent PM who instruments features so the team can answer questions, not just collect data.

CONTEXT: Feature: [FEATURE]. Decisions/questions analytics must answer: [KEY_QUESTIONS]. Funnel or user flow: [FLOW]. Existing tracking and tool: [CURRENT_TRACKING].

TASK:
1. Translate each key question into the specific metric and the events needed to compute it (work backward from the question).
2. Design an event taxonomy: event names (consistent naming convention), trigger conditions, and required properties for each event.
3. Define the core funnels and the segmentation dimensions (properties) you'll need to slice by.
4. Specify identity and session handling: anonymous-to-known stitching and key user/account properties.
5. Provide a QA and validation plan: how to verify events fire correctly and a data-quality checklist before trusting dashboards.

OUTPUT FORMAT: Question-to-metric mapping, Event spec table (Event | Trigger | Properties | Question it serves), Funnel definitions, Identity notes, QA checklist.

QUALITY BAR: Every event must serve a stated question — no tracking for its own sake. Naming must be consistent and future-proof. Include a validation step so no one ships untested instrumentation.
