What's enterprise architecture? The secret blueprint behind resilient growth
Strategy, application architecture, data architecture, and technology architecture explained.

IT Cost and Supplier Risk: One Map for Money and DORA
Cost and ICT third-party risk are usually managed in separate spreadsheets. Mapping applications to suppliers and cost in one model lets you see concentration, license exposure and rationalisation candidates at once — and produce the evidence DORA-minded reviews expect.

NIS2 and Enterprise Architecture: Mapping the Systems and Dependencies Risk Management Touches
NIS2 broadens the entities covered and raises the bar on cyber risk management, supply-chain security and incident handling. Each of those expectations rests on one prior question: do you actually know your systems and how they depend on each other? An EA map is the natural place to hold that — honestly, as evidence, not as a compliance badge.

CSSF and Enterprise Architecture: One Map for ICT, Outsourcing and Resilience Documentation
Banks, PFS, investment firms and fund actors supervised by the CSSF carry recurring documentation expectations around ICT, outsourcing and operational resilience. Each rests on a prior question: can you actually show your capabilities, applications, data flows and the third parties behind them? An EA repository is the natural place to hold that — honestly, as evidence, not as a compliance badge.

From Spreadsheet to Living Model: The ICT Third-Party and Outsourcing Register as Enterprise Architecture
An ICT third-party and outsourcing register is only useful if it is current and queryable — yet most live in a spreadsheet that drifts from reality the day it is finished. Turn the register into a living architecture model: map each critical or important function to the applications and third parties, including the sub-outsourcing chains, behind it, and register, dependencies and concentration stay reconciled. Honestly: an EA repository connects the data and makes the evidence easier to assemble — the register's legal completeness stays yours.

MCP and Enterprise Architecture: Building a Sovereign Context Layer for AI
MCP is the commodity port; the differentiator is a governed, data-residency-aware context layer. Why EA is the natural System of Context — and what regulated finance actually requires.
June 21, 2026
MCP for Enterprise Architecture: 6 Use Cases AI Agents Unlock
From application rationalization to DORA scope to end-of-life risk: six natural-language questions an AI agent can answer against a living EA model — and where each one stops.
June 21, 2026
Thin vs Native MCP: Why the Model Behind the Server Decides Everything
An MCP server is only as good as the model behind it. The difference between a thin API wrapper and a native semantic graph is the difference between a flat list and real impact reasoning — and even that is not enough for regulated finance.

Connecting AI to Your EA Repository: A Compliance Checklist
An EA map is one of the most sensitive assets you can hand to an external AI. A concrete, item-by-item checklist for a regulated EU organization deciding whether — and how — to connect an AI agent to its architecture repository.
June 21, 2026
From Prompt Engineering to Context Engineering: the 2026 Shift
The center of gravity in applied AI has moved from writing clever prompts to engineering the context an agent reasons over. For regulated enterprises, that context lives in enterprise architecture — and must be governed.
June 21, 2026
Context Engineering Explained for CIOs and CISOs
Context engineering is becoming a CIO/CISO concern because an AI agent is only as good — and as safe — as the context it can reach. Here is what it means and what to ask.
June 21, 2026
Ardoq MCP vs Bizzdesign MCP: what "talk to your architecture" leaves out
Ardoq shipped MCP first; Bizzdesign frames thin-vs-native ArchiMate access. Both let AI reason on your model. Neither asks where the data goes — the question that decides it for regulated finance.
June 21, 2026
Should a Regulated Bank Connect AI Agents to Its Architecture?
The EA map is a near-complete blueprint of the bank. Connecting an AI agent to it can accelerate impact analysis and compliance reporting — or quietly leak the blueprint to a US-cloud model. A structured go / no-go framework.
June 21, 2026
Why Most EA Repositories Are Too Stale to Feed an AI Agent
The market is racing to add 'talk to your architecture.' The dirty secret: most EA repositories are incomplete, 12–18 months out of date and hand-maintained — and an agent answers confidently from whatever it is given.
June 21, 2026
Context Acquisition vs Context Exposition: The Real AI-Readiness Gap
Exposing context is a commodity. Acquiring and maintaining good context — across ServiceNow, Jira, Azure, CMDB, IAM and M365 — is where durable value and defensibility live.

Living Architecture: Keeping an EA Repository Agent-Ready
An AI agent inherits the freshness of the repository it reads. Here is the operating discipline that turns an annual snapshot into living context an agent — and an auditor — can trust.

Your Architecture Map Is the Most Sensitive Asset You'll Expose to AI
The incumbents' "talk to your architecture" pitch glosses over one fact: an EA map is the single most revealing document an attacker, competitor or auditor could ask for. Here is what it exposes, why US-cloud LLMs make it a regulatory landmine, and how a sovereign context layer lets AI reason on your architecture without you losing control of it.
June 21, 2026
The Architecture Map as Attack Surface: AI Agents and the New Exfiltration Risk
An EA map is a near-complete blueprint of the organization. The moment an AI agent can traverse it, you have a new exfiltration path — and known controls to contain it.
June 21, 2026
What an Auditor Will Ask About Your AI's Access to Architecture Data
Before you let AI agents touch architecture data, know what an auditor will ask: who can query, where data goes, what is logged, how sensitive objects are protected, who is accountable, and how third-party risk is governed — each with the evidence that answers it.
June 21, 2026
Permission-aware and data-residency-aware: governing AI agent access to your EA
There are two control dimensions when an AI agent reads your architecture: who is entitled to see a given object, and where the data is allowed to physically go. Most incumbents address only the first. Here is a practical control model for both.
June 21, 2026
System of Context vs System of Record: The Layer Missing in the Age of Agents
Systems of Record store what happened. Agents need something else: what exists, who owns it, what data it touches, what regulation applies, what depends on what. That is the System of Context — and it is up for grabs.

Sovereign Context Engineering: A Manifesto for Regulated AI
A manifesto for context engineering done under regulation: five principles for giving AI the context it needs without surrendering control of your most sensitive map.
June 21, 2026
Who Owns the Enterprise Context Layer in a World of Agents?
When agents do the clicking, the prettiest UI stops being the moat. The contested ground becomes the context agents reason on — and for regulated firms, sovereignty and governance decide who owns it.

MCP Is the USB Port, Not the Product
MCP is becoming a commodity protocol. Stop being dazzled by the "MCP support" checkbox and start asking about the quality, freshness, governance and sovereignty of the context behind it.

EU AI Act and Enterprise Architecture: Where to Start by Mapping Your AI Systems
The EU AI Act asks organizations to know which AI systems they run, how risky each is, and how they are overseen. Your architecture map is the most natural place to build that inventory — including the AI you point at the architecture itself.
