TrustSurface Framework Map

Purpose (one sentence)

TrustSurface is a practitioner-led framework for identifying, measuring, and governing the observable trust signals an organisation emits at its digital edge.

What this is

TrustSurface is a neutral, evidence-led model intended to become shared vocabulary. It is published as a public good under Creative Commons licensing.

The conceptual framework stands independently from any specific tool. The website’s interactive components are optional implementations.

Core concepts (vocabulary-stable)

Definitions are stabilised in TrustSurface Glossary v1.0.

  • Trust Surface — the externally-facing systems and signals where trust is experienced.
  • Trust Signals — observable indicators (evidence) describing posture.
  • Trust Posture — the evidence-based state implied by those signals.
  • Trust Signal Gap — intended posture ≠ observed evidence.
  • Operating rhythm — Discover → Assess → Harden → Govern → Signal (repeat).

How to use TrustSurface

If you are a board / exec

  1. Read Board Questions (2–5 minutes).
  2. Request a one-page scorecard and the top trust signal gaps with owners and dates.
  3. Ask how regressions are prevented (change control and cadence).

If you are a practitioner

  1. Build the Trust Surface Inventory.
  2. Apply the Trust Signal Catalogue to produce a baseline scorecard.
  3. Convert gaps into a 30/60/90-day hardening plan.
  4. Establish governance controls to prevent regressions.

If you want the shortest artefact

Read the One-Page Specification (printable summary).
