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 MeaningfulLagging

Customer Satisfaction (CSAT)

A survey-based score measuring satisfaction with a specific interaction, feature, or experience, typically on a 1-5 or 1-7 scale.

Category: Trust
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 per interaction

What it is best for

Measuring satisfaction with specific features or support interactions

What it tells you +

Whether a specific experience met user expectations. More targeted and actionable than NPS.

What it does not tell you +

Predict long-term loyalty or explain what specifically drove satisfaction or dissatisfaction.

When to use it +
  • Measuring satisfaction with specific features or support interactions
  • Before and after changes to key touchpoints
  • Identifying which parts of the experience users value most
When not to use it +
  • As a general product health metric without specifying what was being rated
How leaders misuse it +
  • Aggregating CSAT across all interactions into one number, losing diagnostic value
Anti-patterns +
  • Only surveying users who completed a task successfully, biasing results positive
Companion entries +
Instrumentation or evaluation guidance +

Trigger immediately after specific interactions. Keep surveys short. Include optional free-text.

Examples +

CSAT for the search experience is 58% while CSAT for the dashboard is 89%. The team prioritizes a search redesign based on this gap.

Suggested decisions +
  • CSAT below 70%: specific interaction needs investigation
  • Identify the lowest-CSAT touchpoint and prioritize UX improvement there
