Summary
I am an experienced product and portfolio manager with deep expertise in change management, strategy development, process and audience focus. My approach is based on clarity, flexibility, and strong execution capability.
Strategic Thinking & Audience Focus I look beyond individual requirements and always consider products and processes in a bigger context. The concrete benefit for the audience, data protection, and security are always at the core.
From Uncertainty to Clarity I bring structure to the unknown and turn many variables into a manageable system.
Fast Pattern Recognition & Solution-Oriented Coaching I analyze behaviors, spot patterns, and quickly clarify uncertainties. As a good listener and coach, I help teams and leaders develop the best solutions themselves.
Process Understanding & Complexity Reduction I can quickly grasp, analyze, and explain complex processes clearly – always aiming to make them more efficient and effective.
Inspiring People & Driving Change I excite teams about change, offer guidance, help identify dependencies, and provide confidence in prioritization. With empathy, I create clear focus on shared success and an environment where transformation succeeds.
Tailored Solutions Instead of One-Size-Fits-All I don’t believe in a single method or perfect framework. My mindset isn’t limited to Agile or Lean. I continually seek new, outstanding ideas, no matter their source. Every method, idea, or technique I encounter, I learn, understand, and identify where it works best, then add it to my toolbox. This lets me develop custom solutions with my client that fit their culture and specific challenges.
My credo: The company-specific way of working is crucial – and I help shape it successfully.
