When a funnel chart and the product team disagree, the chart is often wrong. Missing step events, permission dialogs that block a fire, and identity resets between web and app all invent cliffs that never happened in the product.

We pick one revenue-critical path—onboarding, trial start, purchase, or account recovery—and walk it on the devices your users hold while watching the live stream. Every silent miss is logged with reproduction steps and a recommended fix.

Deliverables include a corrected path definition, a release QA script your engineers can replay after each ship, and a short memo separating measurement noise from real product friction.

Typically included

  • Device walkthrough of one critical path
  • Corrected step definitions
