Truth Layer

Truth Layer

The Truth Layer is the badge system that tells you how trustworthy, directional, or risky a measure is.

Why it matters: It helps teams separate meaningful signals from vanity, misuse, or AI distortion before they optimize the wrong thing.

Example: A metric can be Meaningful, Leading, or Vanity Risk.

KPI UX MeaningfulLeading

Funnel Drop-off Rate

The percentage of users who leave a multi-step process at each specific step.

Category: Conversion
Measurement class: KPI

Measurement Class

A measurement class tells you what kind of measure something is, not just what topic it covers.

Why it matters: It stops teams from building a stack full of only KPIs while ignoring value, governance, or AI signals.

Example: Governance Metric and AI Signal are two different measurement classes.

Frequency: Continuous

What it is best for

Diagnosing conversion bottlenecks

What it tells you +

Exactly where users give up. The most actionable conversion diagnostic.

What it does not tell you +

Tell you why users left at that step. Requires qualitative investigation.

When to use it +
  • Diagnosing conversion bottlenecks
  • Prioritizing UX improvements by impact
  • A/B testing specific funnel steps
When not to use it +
  • When funnel steps are not clearly defined or instrumented
How leaders misuse it +
  • Focusing only on the highest drop-off step without considering volume at each step
Anti-patterns +
  • Removing steps to reduce drop-off without checking if the information was needed
Companion entries +

This entry is stronger when paired with:

Instrumentation or evaluation guidance +

Track per-step, not just overall. Include time-at-step to distinguish quick exits from deliberate abandonment.

Sample events

funnel_step_1_entered, funnel_step_1_exited, funnel_step_2_entered
Examples +

A SaaS signup funnel loses 55% of users at the "connect your data source" step. Adding a skip option with sample data reduces drop-off to 28%.

Suggested decisions +
  • Step with >40% drop-off: investigate immediately with session replay or user testing
  • If drop-off is high but conversion quality is good, the step may be filtering correctly
