Over 20 years. Six industries. Always the same challenge: developing governance and decision-making structures that make transformation programs manageable.
The projects on this page show how I've put this into practice.
Rolls-Royce Power Systems AG
Senior Project Lead, Finance & IT · Nov 2024 – Mar 2026 · Manufacturing / Energy Infrastructure · Friedrichshafen
The challenge: A global corporation needed a unified project management and project controlling framework—one that was scalable, applicable across the entire organization, and SAP-based.
My contribution: Design and implementation of an earned-value-based management system using SAP PPM and SAC. Definition of management logic based on costs, progress, and time. Integration of proposal, product, and financial data. Management of interdisciplinary teams in agile and hybrid environments.
The result: a robust framework that aligns project management and financial reporting under a common logic—and enables decision-making at the program level.

My contribution: Finance-side project support for the S/4HANA implementation. Business concept for a group-wide planning guideline covering the income statement, balance sheet, cash flow, and liquidity. Design and implementation of integrated planning in SAP Analytics Cloud.
