Jörg Stumpenhagen – Senior Interim Manager | Digital & Data Transformation
With more than35 years of experience in project and management roles– on both the client and service provider side – I support companies through complex transformations: from strategy to measurable impact in operations.
My focuslies on three closely intertwined areas:
Digital Transformation & Enterprise Architecture:I develop future-proof target states and roadmaps that consistently link business strategy and IT. I draw on established frameworks (TOGAF, Zachman) and bring extensive experience from the industrial, financial services, retail, and public sectors.
Data Management & AI Enablement:Building data governance structures, data quality management, and modern data platforms (Microsoft Fabric, Azure, Purview, Informatica) – with a clear focus on AI Readiness. I identify, prioritize, and manage AI-driven use cases – from automated data analysis to GenAI processes – from conception to implementation, including governance and Responsible AI.
Strategic Project Portfolio & Turnaround:I take on critical situations: stabilizing ongoing programs, building requirements and portfolio management, and managing complex migrations. As an Interim Head of Data or Data Governance Manager, I create structures that provide lasting value after my engagement.
My strengths:calm leadership in high-pressure situations, strong analytical skills, clear communication in heterogeneous stakeholder constellations – and the pragmatism to actually implement concepts.
