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
CP/M at a glance
CP/M, short for Control Program for Microcomputers, is an early disk operating system created by Digital Research. It became a common software base for 8-bit microcomputers using Intel 8080, 8085 and Zilog Z80 processors. Its command-line environment, drive letters and file handling model influenced later personal computer systems.
Where it runs
CP/M appears in legacy business machines, industrial controllers, laboratory equipment, educational systems and embedded products. Companies may need to preserve applications that still support production, testing or historical data access. In Germany, specialists can support local sites remotely or work on-site when hardware access and operational procedures require it.
Core ecosystem
The ecosystem includes CP/M-80, CP/M-86, Digital Research tools, BDOS and BIOS layers, as well as utilities for disks, printers, terminals and serial links. Relevant work may involve:
- Reading and converting CP/M disk images
- Maintaining COM, CMD and HEX program files
- Updating BIOS or hardware-specific drivers
- Connecting legacy systems to modern storage or networks
Typical project work
Freelance specialists help with source recovery, emulator setup, application maintenance and migration planning. They may examine MBASIC, Turbo Pascal, C, PL/I or assembly code, then document its dependencies and operating assumptions. Deliverables often include a working emulation environment, recovered files, interface documentation or a controlled migration path.
When expertise matters
Bring in specialist support when original media is degrading, documentation is missing or a critical machine depends on software that cannot be replaced quickly. Strong professionals can identify the exact CP/M variant, confirm disk geometry, preserve data safely and test changes without risking the live system. They also know when emulation is safer than modifying original hardware.
What distinguishes strong specialists
Good CP/M professionals combine low-level programming knowledge with careful preservation practices. They understand processor architecture, memory limits, interrupt handling, serial communication and vintage disk formats. They communicate constraints clearly, keep reversible backups and validate results on the target machine, an accurate emulator or both.
Frequently asked questions
Questions about CP/M? Start with the answers below.
CP/M is mainly used to maintain, recover or migrate software running on vintage microcomputers and embedded equipment. It can still matter when a production, laboratory or archival system depends on an application that has no direct modern replacement.
CP/M is an operating system, while DOS is a later family of systems with broader hardware and software support. An emulator reproduces a machine or operating environment so CP/M applications can run without the original hardware; it does not replace the original system’s data or business logic.
A strong CP/M specialist often also understands 8080, 8085 or Z80 assembly, C, BASIC, Pascal, serial protocols and vintage disk formats. Knowledge of emulators, disk imaging, hexadecimal file analysis and modern scripting is useful for recovery and migration work.
The required experience depends on whether the work involves simple file access, application changes or hardware-level recovery. A basic conversion may need focused system knowledge, while undocumented BIOS behavior, damaged media or custom peripherals call for a professional who can inspect code and hardware together.
CP/M projects can often be handled remotely when disk images, source files and emulator access are available. On-site work in Germany is more suitable when the original machine, custom peripherals or restricted equipment must be tested directly; clear documentation and secure file transfer are essential in either model.
Before starting CP/M work, collect the machine model, processor type, operating system variant, available disks, backups and application files. A description of the business process, known failure symptoms and any working hardware helps the specialist define a safe recovery or maintenance plan.
Look for a professional who can explain the system’s BIOS, BDOS, storage layout and application dependencies in plain language. Quality work preserves original media, uses verified copies, documents every change and proves the result through repeatable tests on the target setup or a faithful emulator.
CP/M maintenance can be risky because source code, tools and hardware documentation may be incomplete, while old media can fail during repeated access. Uncontrolled changes may alter timing, memory use or disk compatibility, so specialists should work from images and backups, keep changes reversible and test on non-production equipment first.
The average hourly rate of freelancers in Germany who have used CP/M in their recent projects is 94 €, which corresponds to a daily rate of about 755 € based on an 8-hour working day.
