Deferred Abandonment & Activation Funnel Tracker

Most funnel reviews lie to you. A product change improves Add-to-Cart by 4 points — but nobody checks whether Order Confirmation dropped 5. That's deferred abandonment: users move past one step only to stop at another, and the net impact is negative even when a single metric looks healthy. This tracker applies Crystal Widjaja's altitude map methodology from Reforge to give analytics leads and PMs a structured, cohort-based view of every step in their activation funnels — and the cross-cohort delta layer that makes deferred abandonment visible instead of hidden. What's included: a three-sheet workbook (Funnel Steps, Funnel Definitions, Cohort Comparisons), a Kanban board for funnel step progress, and an 8-step task that scaffolds a complete funnel definition, step-by-step data entry, and cohort comparison from scratch. Built for Analytics Leads and PMs at product-focused companies who need the documentation and tracking layer to make funnel reviews reliable across the team.
