ECM™
Enterprise Coherence Model
An integrating governance layer of five interdependent layers (Capital, Architecture, Operations, Risk & Compliance, Innovation), each with a board-reportable coherence metric.
Clarity in technology governance.
Glossolalie Advisory formalises thirty years of international technology experience into six governance frameworks, documented by their author, Thierry Sayegh-Sauvage.
The layered model: choose a framework

Six governance frameworks
Each framework governs one dimension of a single discipline: the divestiture, depreciation and structural ageing of technologies and of delegations. Each one has a detailed summary on this site, and a full whitepaper shared by the author on request.
PLCF™
Product Lifecycle Closure Framework
Governance of product closure: the Product Decay Index (DXi), the GTM Sunset Playbook and chargeback of the cost of debt retention.
VEGA™
Vendor & Enterprise Governance Architecture
The vendor portfolio governed as an architectural artefact: a four-level maturity model and an Integrated Vendor Score (IVS) on four axes.
TDG™
Technical Debt Governance
Technical debt remediation treated as a capital allocation decision: a governed inventory, the Remediate, Contain and Write-Off regimes, and a Technical Risk Register.
CORE™
Competency and Organisational Resilience Equilibrium
Technology competency governed as depreciating capital: the Build, Source and Retire regimes, and a Competency Risk Register for the board.
LEGATE™
Legitimacy Governance for Agent Task Execution
An adaptation of the agent harness pattern: mandate, boundary, gates, evidence, interruption and retirement of AI agents, measured by the Execution Legitimacy Score (ELS).

Convictions
What we believe
-
Instruments to operate
A framework nobody operates is a dead document. The value of a framework is measured by its capacity to be activated daily.
-
Governance is an operational capability
Compliance sets the minimum that can be demanded, and governance begins beyond it. Organisations that treat governance as a reporting exercise never develop the decision-making capacity that effective oversight demands.
-
Technology is a capital allocation decision first
Return, risk, depreciation horizon. Every architectural decision is a capital allocation decision. Treating technology otherwise leads to under-optimised portfolios and under-priced risk.
-
Precision before persuasion
Name the problem before proposing the solution. Transformation rhetoric more often conceals diagnostic failures than it accelerates change.
Public code
Engineering
Seven public repositories, six of them forming a chain in four links: decide, measure, operate, prove. Every governance claim here is a piece of code with a test that proves it refuses.
The repositories are tested on a home lab: virtual machines, containers and functions are described node by node.
