AII
Assurance Intelligence Index
Quantifying Assurance, Integrity, and Trust Across the ECO Number Network
1. Assurance Architecture Overview
The ZAYAZ Assurance Intelligence Index (AII) provides a quantitative measure of data quality, process integrity, assurance maturity, and ecosystem trust across the ZAYAZ federation.
AII serves as the measurable expression of the assurance architecture.
While TRACE establishes provenance, OARM validates reproducibility, AFLE enables federated assurance, DAL guarantees integrity, and AIATI generates assurance intelligence, AII converts those signals into a transparent and interpretable assurance score.

AII functions as the assurance currency of the ECO Number Network.
2. Purpose
The Assurance Intelligence Index provides a standardized mechanism for evaluating:
- trustworthiness
- integrity
- transparency
- assurance maturity
- reproducibility
- ecosystem reliability
across organizations, suppliers, products, carbon passports, and federated assurance networks.
The objective is to transform millions of assurance events into a single, interpretable indicator suitable for:
- management
- auditors
- regulators
- investors
- procurement teams
- federation participants
3. Strategic Objectives
| Objective | Description |
|---|---|
| Assurance Visibility | Make assurance quality measurable |
| Trust Benchmarking | Compare assurance performance |
| Continuous Improvement | Encourage trust optimization |
| Federation Intelligence | Measure ecosystem trust |
| Regulatory Transparency | Support defensible reporting |
| Carbon Passport Validation | Measure passport quality |
| Risk Awareness | Surface emerging assurance risks |
| Governance Support | Support policy and oversight |
4. Core Concept
AII is not a trust score.
Trust is only one contributor.
AII measures the overall quality of an entity's assurance ecosystem.
