ERP Program Manager at Fiserv
The customer is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a standard template worldwide.
The program also includes the “RISE with SAP” migration and modernization program, which may involve migrating the landscapes of selected country installations to the SAP Private Cloud.
On the stakeholder side, the program reporting line extends to the company’s executive board and that of the implementation partner.
Fiserv Germany’s ERP landscape currently includes several non-standard SAP tools and applications that extend the functionality of the ECC environment and can often be integrated into downstream systems. As part of the transition to SAP S/4HANA, it is essential to assess the core functionality, integration points and future viability of these applications in order to determine their alignment with the target architecture.
The focus of the work is on providing expert advice and assessment to define the scope, strategy and roadmap for transitioning Fiserv Germany’s SAP ECC system to SAP S/4HANA.
The recommended best practices from SAP 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 and ensures alignment with industry best practices, regulatory compliance and future scalability.
Migration Strategy Definition – assessment of 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 required to implement the necessary functions in SAP S/4HANA and to identify opportunities for process optimization.
Roadmap for Non-SAP Systems and Applications – assessment of third-party and legacy applications regarding their integration with SAP S/4HANA and recommendation of consolidation, migration or replacement strategies.
Deployment & Implementation Planning – defining a phased approach for implementation, including project schedules, risk mitigation strategies and key milestones aligned with business priorities.
This transformation takes place in phases: the Discovery phase leads to the Explore phase, which is followed by the Design phase and finally implementation.

About the technology
What CP/M is
CP/M, short for Control Program for Microcomputers, is an early disk operating system created for systems built around Intel 8080, Zilog Z80 and related processors. It provided a consistent command-line environment, file handling and program execution across hardware from different manufacturers. Digital Research is the vendor name most closely associated with its original release.
Where it runs
CP/M appears in vintage personal computers, industrial controllers, laboratory equipment, office machines and embedded products that remain in service because their original software still performs a critical task. Companies may also encounter CP/M in archives, recovered source code, disk images or machines that cannot be replaced without changing a validated process. Its compact design suits constrained hardware but demands careful handling today.
Core ecosystem
The ecosystem includes the BDOS and CCP system components, BIOS adaptations, console and disk drivers, and utilities such as PIP, STAT and SUBMIT. Common project work involves 8080 or Z80 assembly, MBASIC, Pascal, C, disk-image formats and serial communication. Specialists often work with physical floppy media, emulators, cross-assemblers and modern version-control workflows.
- Inspect CP/M disks, images and directory structures
- Adapt BIOS, console or storage routines
- Recover, document and rebuild legacy applications
- Test software on original hardware and emulators
When expertise matters
Freelance expertise is useful when a company must recover a system without complete documentation, migrate files from obsolete media or keep a production device operational. It also helps when a replacement threatens compatibility with proprietary formats or established procedures. In Germany, remote work is often practical for source analysis and emulation, while hardware diagnosis may require access to the original site.
- Recreate a build environment from old tools
- Port a utility to compatible modern hardware
- Convert CP/M data into usable current formats
- Create maintenance documentation for internal teams
Strong professional practice
Strong CP/M professionals understand both the operating system internals and the hardware assumptions behind each implementation. They distinguish platform-specific BIOS behavior from portable application code, preserve file metadata, and verify results against original machines where possible. Clear documentation matters because undocumented changes can make a fragile legacy system harder to maintain.
Choosing the right specialist
Look for evidence of work with the relevant processor family, storage medium, language and machine model rather than relying on CP/M knowledge alone. Ask how the specialist handles disk-image preservation, emulator differences, binary-only software and rollback plans. For German projects, agree early on language needs, hardware access, security restrictions and how remote findings will be validated on site.
Frequently asked questions
Questions about CP/M? Start with the answers below.
CP/M is mainly used to maintain vintage computers, industrial equipment, laboratory systems and archived software that still depends on its original environment. A specialist can recover programs and data, emulate the system, or connect an old workflow to newer hardware.
CP/M offers a compact command-line environment with a hardware-specific BIOS and a portable application layer. DOS became more widespread on later personal computers, but CP/M knowledge remains important when software, file formats or hardware interfaces cannot be moved directly.
CP/M work often requires 8080 or Z80 assembly, disk-image analysis, BIOS adaptation and serial communication knowledge. Experience with MBASIC, Pascal, C, cross-assemblers, emulators and vintage storage media is also valuable.
CP/M projects need practical evidence with the relevant machine, processor, storage format and software language. A strong specialist should be able to explain how they will preserve original data, reproduce the environment and test changes without risking the working system.
CP/M source analysis, disk-image work and emulator testing can often be completed remotely from Germany. Physical faults, unusual peripherals and media recovery may require on-site access or a local partner with the original equipment.
CP/M work starts more smoothly when the company provides the machine model, processor details, available disks or images, known software names and the required outcome. Photographs, interface documentation and a safe copy of every original medium can prevent avoidable delays.
CP/M quality is shown through reversible changes, preserved disk images, repeatable builds and tests against original behavior. Ask the specialist to document assumptions, distinguish emulated results from hardware results, and explain how recovered files were verified.
CP/M knowledge is relevant when a modern project must preserve an old protocol, data format or control workflow. Specialists who understand Digital Research tools and the underlying 8080 or Z80 environment can often bridge legacy behavior with contemporary systems without discarding valuable historical software.
