Situation: Corporate Merger SAP Consulting at Scale
As part of a merger & acquisition, a global $8B automotive parts company acquired another $8B automotive parts company. Their strategy was to split each company, combine complementary business units, and spin off two new companies. One company would retain the operating environment — data centers, infrastructure, applications, ERPs, databases — and the other would require the complete build-out of a new technical environment.
The client established several functional SAP HR program tracks, each focused on specific functional needs and aligning IT for support and development. In order to spin both companies simultaneously, all functional programs needed to be ready at the same time. The HR program was at risk of not being ready — threatening to delay the spin of both new companies and costing the organization millions of dollars.
Challenge: 15 Projects, 21 Countries, 50,000 Employees
The client needed program leadership to rescue and deliver the SAP HR program. The program consisted of 15 projects that needed to be implemented for the creation of the newly spun company — ranging from SAP HCM consolidation projects to the implementation of SAP payroll across a global workforce.
These projects supported operations in 21 countries, over 90 manufacturing facilities, and over 50,000 employees. With payroll running on both weekly and monthly cycles, it was absolutely critical that payroll executed successfully from day one — any failure would mean employees were not paid. The scale and complexity of this SAP HCM implementation had no margin for error.
Action: SAP Program Recovery & Delivery Leadership
Full On Consulting met with business leaders and executives to develop a clear picture of the SAP HR program and the challenges it faced. Our team applied proven SAP program management best practices — working with business and IT teams to prioritize initiatives, align workstreams, and implement structured project governance across all 15 projects.
Project plans were reviewed, revised, and baselined. Agile development processes were introduced to keep teams focused and maintain visible progress. Our team also took a strategic view of the overall HR program — analyzing potential impacts from other functional workstreams and working cross-functionally to identify business processes spanning multiple areas. This ensured no integration points were missed during the SAP HCM recovery.
The culmination of all 15 projects was the cloning of the global SAP HR technical and operating environment for the newly spun company — the most complex and highest-risk deliverable in the entire corporate merger SAP consulting engagement.
Result: On-Time Delivery Across 21 Countries
All 15 HR projects were delivered on time and the overall SAP HR program was completed successfully — enabling the planned spin of both new companies on schedule. This is a defining SAP program management results story: a program that was at serious risk of failure was turned around and delivered across 21 countries, 90+ manufacturing facilities, and 50,000+ employees without a single payroll disruption.
The success of this engagement required extraordinary planning, coordination, and execution across globally distributed teams in 21 countries — making it one of the most complex SAP consulting results in Full On Consulting's history and a model for large-scale HR system implementation case study best practices.
Client Testimonial
“Don and I worked together at Tenneco/DRiV on the HRIS Program for the integration of Federal Mogul. Don is a great colleague and leader during times of challenge and change. The HRIS program consisted of 14 subprojects — of which cloning and carving the core global SAP HCM instance was at the center.
From the beginning, Don took great care to understand the project, stakeholders, and deliverables of the full program. I knew that with Don as the program manager, I did not have to worry about meeting our aggressive timeline for operational separation. He is a great project manager with extensive experience who knows how to get things done.
There were many challenges with such a complex global program — engaging stakeholders, tracking budgets, and finding the right resources and solutions for complex and uncharted processes and applications. Don always found the answers with poise and patience, and we could not have accomplished our goals without him!”
