Buyer Trust Score (BTS)

Technical Specification

1. Definition

The Buyer Trust Score (BTS) is a proprietary weighted composite index (0–100) measuring aggregate behavioural certainty across the six Trust Checkpoints within the RAMMP Pre-Spend Diagnostic.

The Buyer Trust Score quantifies structural trust stability prior to marketing capital deployment.

2. Purpose

The Buyer Trust Score exists to:

  • Provide a single quantitative measure of buying journey integrity

  • Identify structural instability prior to budget amplification

  • Support capital allocation decisions

  • Establish threshold-governed marketing due diligence

The Buyer Trust Score is not a performance vanity metric.
It is a pre-spend risk control indicator.

3. Scale and Interpretation

The Buyer Trust Score is expressed on a 0–100 scale.

Interpretation bands:

  • 80–100: Structurally stable

  • 65–79: Stable with moderate leakage

  • 50–64: Structurally at risk

  • Below 50: Structurally unstable

Interpretation bands are indicative and may evolve as calibration data expands.

4. Structural Composition

The Buyer Trust Score is derived from performance across six Trust Checkpoints:

  1. The Arrival

  2. The First Impression

  3. The First Date

  4. The Honeymoon

  5. The Reality

  6. The Moment of Truth

Each checkpoint:

  • Receives a stability score (0–100)

  • Is evaluated against a defined minimum threshold

  • Contributes to overall BTS through proprietary weighting

5. Weighting Model

The Buyer Trust Score operates under a proprietary weighted model.

Weighting:

  • Reflects the relative structural impact of each Trust Checkpoint on revenue stability

  • Accounts for risk amplification potential

  • Is calibrated using observed behavioural patterns

Detailed weighting logic is proprietary and not publicly disclosed.

6. Threshold Constraints

The Buyer Trust Score operates under threshold governance principles.

Principles:

  • Each Trust Checkpoint has a defined minimum stability requirement.

  • Material deviation from threshold increases structural risk.

  • Failure in critical checkpoints may constrain or cap the overall Buyer Trust Score.

  • High performance in non-critical checkpoints cannot fully offset critical instability.

The overall score cannot exceed structural integrity.

7. Relationship to Revenue Feasibility

The Buyer Trust Score informs, but does not replace, the Revenue Feasibility Index (RFI).

High Buyer Trust Score + Low Revenue Feasibility Index
→ Under-leveraged demand or misaligned targets.

Low Buyer Trust Score + High Aspirational Revenue Target
→ Amplified capital risk.

The two indices operate together within the Pre-Spend Diagnostic.

8. Decision Governance

The Buyer Trust Score is used to inform the structured verdict protocol:

STOP
KEEP
FIX
PROVE

A materially unstable Buyer Trust Score:

  • May trigger STOP verdict

  • May restrict budget expansion

  • Requires structural correction prior to capital amplification

The Buyer Trust Score governs decisions.
It does not prescribe execution.

9. Methodological Integrity

The Buyer Trust Score:

  • Uses behavioural and commercial inputs

  • Applies proprietary weighting logic

  • Incorporates threshold calibration

  • Is version-controlled

Scoring methodology may be refined over time to reflect expanded calibration datasets.

10. Intellectual Property

The Buyer Trust Score forms part of the patented RAMMP Pre-Spend Diagnostic methodology.

RAMMP is protected by granted patents in Australia and New Zealand, with patent pending in the United States.
