Mathies WähnerIT Governance Deutsch

Stabilize IT. Take on responsibility. Move programs forward.

I take on IT leadership and program roles for a defined period. I lead teams, manage providers and get critical initiatives moving again – with clear priorities and binding decisions.

For executive management and IT leadership – particularly in energy supply, infrastructure and industry.

Supporting services

Provider management and transition

When work with a provider stalls or a change of provider is coming: clarify scope, responsibilities and escalation paths, and steer operations or the transition to firm commitments.

IT procurement support

Bring requirements, evaluation logic and bidder commitments together into a decision paper that can be traced – in coordination with procurement and legal counsel.

Ongoing governance support

Support executive management and IT leadership regularly on priorities, risks and upcoming decisions, and follow up on the implementation of agreed actions.

Approach

The governance of stability

Many of the IT issues that reach executive management have a structural cause: one role is responsible for something another role decides. A handover has no agreed end date. A metric counts outages but says nothing about who keeps things running. The work starts by clearing that up.

Clarify structures

I make responsibilities, decision paths and interfaces visible and connect them with clear expectations of the roles involved.

Evidence, not impressions

Every rating states what it rests on: documents, interviews or both. Anything not yet confirmed appears in the report as an open point.

Authority goes with responsibility

Responsibility is taken on together with the authority to exercise it. Sponsor, escalation path and the end of the engagement are settled before the start.

About me

I come from operations: team leadership, service ownership, incident and SLA accountability in regulated environments, before moving into IT governance and program leadership. That is where my way of working comes from: facts first, then the assessment, then the options.

I lead every engagement personally and remain the direct contact from the first question to the handover. On LinkedIn and at itsm.tools I write about the governance of stability.
