Did the user discover the path?
Prompt impressions, tour widget opens, checklist views, CTA clicks — if nobody sees the prompt, it is a prompt problem
Did the user start the guided flow?
Tour starts, wizard starts, onboarding-path selection events — low start rate with high prompt visibility = ability barrier
Where did the user get stuck?
Step views, step completions, step failures, abandonment events, time in flow — shows exactly where the ability chain breaks
Did the user reach first value?
First meaningful activation event, time to first value, path source — the moment that separates activate from churn
Conversion by prompt type, checklist completion, guided-tour completion, follow-on behavior — compares prompt performance, not just existence
