Summary

I am happy to support the transformation of companies to increase effectiveness, improve efficiency, and anchor methodological knowledge, thus driving cultural change across all levels of hierarchy. My field of work covers management systems in the improvement areas of quality, Six Sigma, Lean, Agile, Scrum, and cultural change in the roles of project manager, expert, coach, and trainer.

A sustainable and holistic perspective, together with a focus on the key objectives, defines my understanding of meaningful work. Revising existing or designing and documenting functional areas of responsibility, standards, and processes is at the heart of my work. The inspiration from teamwork is just as important to me as independent, conceptual, and strategic work. I appreciate a varied field of activity that requires familiarization and further training in new topics.
