• Process optimization: Identification of weaknesses and inefficiencies, development and operational implementation of improvement measures
• Stakeholder management: Identification and analysis of all relevant internal and external stakeholders; structured communication and coordination with previous and future owners, shareholders and employees
• Change management: Supporting the workforce and management through the handover process; building acceptance and trust among all participants
• Governance & documentation: Creation and handover of structured operation manuals, process documentation and organizational handbook for the new business owner

• The client is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a global standard template.

• The program also includes the migration and modernization initiative "RISE with SAP", which may involve migrating selected country installations to the SAP Private Cloud.

• On the stakeholder side, the program's reporting line extends up to the company's board and the implementation partner's board.

• Fiserv Germany's ERP landscape currently includes several non-standard SAP tools and applications that extend the ECC environment's functionality and often integrate with downstream systems. As part of the move to SAP S/4HANA, it is essential to assess the core functionality, integration points, and future viability of these applications to determine their alignment with the target architecture.

• The focus of the role is to provide expert advice and assessment to define the scope, strategy, and roadmap for migrating Fiserv Germany's SAP ECC system to SAP S/4HANA.

• SAP's recommended best practices are followed, and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.

• This assessment forms the basis for a successful SAP S/4HANA transformation, ensuring alignment with industry best practices, regulatory compliance, and future scalability.

• Migration strategy definition – evaluating available transition approaches based on business objectives, technical feasibility, and SAP best practices.

• Technical readiness assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points, and infrastructure readiness for SAP S/4HANA.

• Business process impact analysis – reviewing the latest business process documentation to define the scope and effort needed to implement required functions in SAP S/4HANA and identify process optimization opportunities.

• Roadmap for non-SAP systems and applications – evaluating third-party and legacy applications for SAP S/4HANA integration and recommending consolidation, migration, or replacement strategies.

• Deployment & implementation planning – defining a phased rollout approach, including project timelines, risk mitigation strategies, and key milestones aligned with business priorities.

• The transformation is carried out in phases: the discovery phase leads to the explore phase, which then leads to the design phase and finally to the implementation phase.
