Senior Transition Manager - Large Scale Supplier Exit

London

Senior Service Transition SME

My client is exiting a heavyweight supplier agreement under challenging and tricky conditions.

This is a complex, high-profile and high-visibility technology transition requiring coordination across senior stakeholders.

I am interested in senior candidates who have successfully managed a large scale transition like this before and have references, examples & ability to expand on their contribution in granular detail.

You will lead end-to-end delivery, from early-stage preparation, tender support, and transition planning, through to testing, go-live, implementation, and post-launch maintenance. You will have a well resourced programme team around you to support and deliver.

Experience:
⭐ Leading complex service transitions across public and private sector contracts.
⭐ Building and executing full lifecycle transition plans, aligned to programme milestones.
⭐ Acting as the single point of accountability across stakeholders and incoming suppliers.
⭐ Managing infrastructure setup, data migration, access provisioning and supplier onboarding.
⭐ Driving change communication and ensuring business readiness from day one.
⭐ Owning service integration, acceptance testing, go-live and smooth handover into BAU.

I am not looking for candidates who have done one aspect of brief above, I am looking for proven candidates who can say they’ve successfully delivered mammoth programmes like this before, reporting to Senior Executives and dealing with big tech suppliers.
