Funnel

Stages that shrink — marketing and ads love it; science class should ask whether the widths are honest.

100 64 41 22 11
Funnel

Funnel encodes values as width (or area) of successive stages. Sales-management language of the mid-20th century; later CRM dashboards.

In reports, ads and assignments it fits ordered drop-off: leads, checkouts, applications. Skip it when stages are not nested subsets of the same population.

This page gathers anatomy, fit, craft, failure modes and work / ads / school recipes for Funnel.
