About the Role
The Technical Programme Plan Manager is accountable for the integrity, feasibility and credibility of the integrated technical programme plan. Working in partnership with the Enterprise Transformation programme workstream leads and third-parties (SI and SAP) this role ensures the technical plan covers technology, data, integration, testing and technical deployment activities required to deliver the transformation objectives. The role acts as the single source of truth for technical planning and forecast confidence, challenging assumptions and surfacing risks early to protect delivery outcomes.
Key Responsibilities:
Integrated Technical Programme Planning
Build, maintain and govern the end-to-end integrated programme plan, covering technology, data, integration, environments, testing, cutover and stabilisation.
Ensure coherent sequencing across technical workstreams, interdependent programmes and external partners (SI, SAP, other vendors as required).
Maintain end-to-end traceability from SAP design decisions through build, test, cutover, and deployment sequencing within the technical programme plan.
Ensure plans account for SAP environment readiness, including development, test, pre-prod, prod provisioning, connectivity and RISE dependencies.
Act as the primary technical planning point of contact across workstream leads and delivery partners.
Ensure plans reflect S4 specific test realities (including SIT, UAT, regression, integration testing, mock conversions, and defect remediation cycles).
Dependency & Critical Path Management
Identify, model and manage cross‑programme technical dependencies (SAP core, data, integrations, environments, third-party systems).
Own and communicate early and clearly the true technical critical path, highlighting constraint drivers, bottlenecks and sequencing risks.
Partner with the Deployment Lead to integrate technical cutover planning into the master programme plan, including rehearsals, dress rehearsals, data freezes and “go / no go” windows.
Assess and articulate downstream planning impacts across environments, testing, deployment waves, and resource demand.
Ensure technical cutover planning reflects operational and business continuity constraints, not just technical task completion.
Plan Governance & Assurance
Maintain full traceability between technical decisions, scope changes, assumptions and plan impacts.
Own technical planning standards, assumptions, and integration of change control impacts into the master plan.
Integrate and reconcile SI-provided SAP plans into the master plan, maintaining independence and transparency.
Partner with the PMO Lead and Programme Governance Lead to enable decision-ready conversations with leadership, focused on options, impacts and consequences.
Progress Tracking & Forecasting
Provide forward-looking confidence assessments for S4 milestones (design freeze, test entry/exit, migration readiness, cutover) not just date forecasts.
Track delivery performance against plan and produce credible forward-looking forecasts (not just retrospective status).
Integrated risks, issues, and mitigations into the plan in partnership with RAID owners.
Continuously stress test plans for feasibility, capacity, sequencing and risk.
Profile & Experience:
Expert in integrated, multi-year transformation programme planning across technology, data, integration, testing and deployment streams.
Deep capability in critical path analysis, dependency modelling, and constraint management in complex programmes.
Strong understanding of S/4 HANA delivery including design-to-build traceability, SAP specific testing cycles, deployment wave patterns and cutover constraints.
Strong understanding of programme governance, including design authorities, stage gates and executive decision forums.
Able to translate strategic intent and governance decisions into executable, time-phased delivery roadmaps.
Able to influence without formal authority across business and technology leaders; confidence challenging plans and assumptions constructively.
Able to communicate complex technical planning realities in clear, decision-grade language.
Able to present options, trade-offs and consequences clearly to senior-leadership.
