Description du poste

As TCS France accelerates new programs across IT Infrastructure, Cloud, Application Support and SAP, the Transition Manager is accountable for end-to-end service transition from current state to steady state operations. The role ensures a controlled, risk-managed handover of services (people, process, technology, governance and tooling) while protecting business continuity, service levels and customer experience.

1. Purpose & Scope

• Lead transitions for new logos, renewals, vendor takeovers, carve-ins/carve-outs, and major transformations impacting Run services.
• Cover service lines including IT Infrastructure (EUC, Network, Data Center, Workplace), Cloud (AWS/Azure/GCP, landing zones, migrations), Application Support (L2/L3, DevOps-enabled support), and SAP (AMS, S/4HANA programs, integrations).
• Own transition governance, planning and execution across onsite/offshore teams and partner ecosystems, ensuring readiness for steady-state operations.
• Ensure compliance with contractual obligations, security and regulatory requirements (e.g., data protection, audit controls), and TCS delivery standards.

• Transition Planning: Build an integrated transition plan (workstreams, milestones, deliverables, RACI, resourcing, budget), define acceptance criteria and entry/exit gates, and establish governance cadence.
• Knowledge Acquisition & Documentation: Drive knowledge transfer from incumbent teams/vendors; create/update runbooks, SOPs, architecture diagrams, CMDB/service maps, support model, and escalation paths; validate knowledge via walkthroughs and simulations.
• Process & Tooling Readiness: Ensure ITIL processes (Incident/Problem/Change/Request/Knowledge/Asset) and tool configuration (ServiceNow or equivalent), monitoring, alerting, access management and reporting are ready for operations.
• Service Transition & Cutover: Plan and execute cutover/go-live, including access provisioning, operational handover, on-call rosters, parallel run (if needed), and communications; manage hypercare and warranty periods.
• Service Acceptance & Stabilization: Obtain formal sign-offs, baseline KPIs, confirm SLA achievement, and transition into BAU governance with continuous improvement backlog.

2.2 Governance, Reporting & Stakeholder Management

• Set up and run transition governance (SteerCo, weekly transition reviews, RAID reviews, daily cutover calls as required).
• Own RAID (Risks, Assumptions, Issues, Dependencies) log and drive mitigation plans, escalations and decision making.
• Provide consolidated reporting on progress, readiness, budget, resourcing, quality and key decisions to Delivery/Program leadership and the customer.
• Coordinate with internal teams (Delivery, ISM/Security, Architecture, HR/RMG, Finance, Procurement, Legal, PMO) and external partners/vendors.
