CIOs, Risk functions and Executive Committees — Mid-Caps, Large Groups & International

Resilience, operational autonomy, environmental footprint.
Built into your IT strategy — or absorbed by it?

Every architecture left unarbitrated is an architecture absorbed, and its consequences are paid over five to ten years: contractual costs, dependencies that have become irreversible, consumption nobody planned for.

An IT master plan is driven by business priorities, and those are yours. LUTECIUM works on the three cross-cutting subjects that are rarely examined together within it: the graph of critical dependencies, the quantification of the risks they induce, and the associated carbon emissions. And works with you on the architecture options that preserve your room for manoeuvre.

One counterpart, twenty years spent on the other side of the table: enterprise architecture, programme management, IT executive committee of a capital markets bank. No layered consultancy, no black-box tool.

Flash diagnostic

3 to 6 weeks to identify what your IT master plan does not cover.

An exposure review across three axes — cost, risks, footprint — to identify the priorities and frame any work needed to correct course.

Deliverables

  • The critical functions selected and the first map of the dependencies that carry them — vendors and third parties, software components, infrastructure, AI models.
  • Orders of magnitude across the three axes: what these dependencies cost, what they put at risk, what they emit.
  • The blind spots: what your IT master plan does not address, and the trade-offs it will have to rule on.
  • What comes next: what deserves detailed quantification, in what order, and at what cost.
  • A one-hour readout to the executive committee.

Duration

8 to 15 consulting days over 3 to 6 weeks.

How it runs

Interviews, document review, joint construction of dependency graphs, readout workshop.

Possible next steps

Detailed quantification of a given perimeter, contribution to the IT master plan, programme framing, training.

Drivers & Mapping

Connecting business performance and IT resilience

The triple constraint on the modern IT department

  • Support innovation: accelerate the digitalisation and technological transformation of the business lines.
  • Guarantee the durability of services: deliver environmentally responsible infrastructure while strengthening its robustness.
  • Keep budgets under control: reach these performance and transition objectives within a strict budgetary envelope.

Overall sustainability, driven by the business

This sustainability is no longer a theoretical concept but a firm contractual requirement from clients and their regulators, and it now plays out on two fronts:

  • Systemic robustness: end-to-end resilience against cyber threats, energy crises and extreme climate events.
  • Control of environmental impacts: control of the low-carbon trajectory of the information system.

The opportunity: the virtuous circle of Lean IT

OPEX optimisation: eco-design of your architectures, rationalisation of your applications and extension of hardware life cycles reduce your run costs immediately.

CapEx reinvestment: this "financial dividend" released by digital sufficiency makes it possible to provision and fund redundancy infrastructure, sovereign alternatives and fallback solutions.

Outcome: an IT department better aligned with the finance function, compliant with client requirements, and inherently more resistant to technological and climate shocks.

Market reference for digital sufficiency in a large group: €23m per year in financial return and 11,000 tonnes of CO2e (ref. EDF — source Boavizta).

Engineering & Governance

Engagement methodologies, grounded in international standards

We work at the intersection of environmental performance (sustainability) and risk engineering (IT & Risk), from an enterprise architect's standpoint.
