Interim lead for IT governance or programs

Taking over a leadership or program role in IT for a defined period, with agreed authority and an agreed end. Usually six to twelve months, three to five days a week, remote and hybrid.

Six to twelve months

the usual duration; three to five days a week.

Settled before the start

Responsibilities and decision-making authority for the engagement: sponsor, reporting line, escalation path, end of the engagement.

Orderly handover

to a successor, with reporting and responsibilities that keep running.

Situation

When the role is needed for a period

A role is vacant

The IT lead, a service owner or a program lead has left or is not yet replaced, and the topics do not wait.

A program has escalated

Deadlines, providers or decisions have reached executive management, and the organization lacks the time to lead it.

A transition is coming

A provider change, a separation of legal entities, or a new IT lead who should take over an orderly state.

Contribution

What the role covers

  • Leading and developing teams, including objectives, feedback and performance management within the agreed remit.
  • Reporting to executive management, in a fixed rhythm.
  • Setting priorities: which decision comes first, which can wait, which cannot be made yet.
  • Taking on escalations and leading them to a decision.
  • Managing providers: scope, SLA framework, escalation paths.
  • Decision papers for executive management, the supervisory board or shareholders.
  • Change governance where changes touch operations.
Clarify structures

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

Handover as the goal

The aim is a program or IT function that runs predictably again, and a successor who takes over with reporting, responsibilities and open points in hand.

Not part of the work: technical implementation and operations, security or compliance attestations, and legal advice.
