• After several S/4 go-lives, structure, role clarity, and decision clarity were missing in Finance and IT; governance mechanisms, prioritization logic, and responsibilities were not defined well enough.

• Unclear interfaces, high coordination effort, and inconsistent ways of working led to organizational instability and limited leadership and steering capability.

• The existing operating model between Finance, Controlling, and IT was not working, which affected transparency, collaboration, and decision paths.

• Designed the transformation and organization architecture for Finance and clarified roles, decision paths, and priorities.

• Diagnosed and structured the Finance and IT organizations (DE/UK/PL), including collaboration, responsibilities, and interfaces.

• Redesigned the Finance–IT operating model with a focus on governance, steering routines, and cross-functional collaboration.

• Enabled leaders and teams, especially Global Process Owners, Key Users, and Finance Leads (systemic organizational development / leadership).

• Steered the transformation portfolio, including clarity on risks, dependencies, and cross-functional decision processes.

• Restored structural steering capability by clearly defining roles, decision paths, and priorities and anchoring them across the organization.

• Strengthened governance and cross-functional collaboration in a systemic way - Finance, Controlling, and IT worked again in consistent, aligned structures; friction losses dropped measurably.

• Harmonized working and communication logic, making coordination faster, more transparent, and less conflict-heavy.

• Enabled the organization in a sustainable way, including the build-up of a strong Key User / Process Owner community and clearly defined steering routines.

• Made the transformation structurally manageable - prioritized initiatives, clear risk and progress logic, and consistent decision formats increased execution speed.
