After completing my studies in engineering at the RWTH in Aachen I spent four years in the USA as development and project manager in automation technology. Following that I oversaw the finalisation of large-scale projects in postal and airport automation, was active for years as manager and as director of limited companies, and then was engaged as segment manager for Siemens AG in charge of products for the high-voltage technology in factories in Europe, Asia, and Americas. Following that and driven by the urge for new enterprise, I founded and am manager of the OPMC – Operational Management Consultancy – as free-lance consultant and interim manager both independently and within a network of internationally experienced top consultants.
I have proven my specialized and implementation competence in the course of decades in international business circles.

Dr.-Ing. Uwe Reitz
Uwe Reitz, all my life I have been involved with organisation and management, working passionately towards a goal, developing and implementing strategies and plans. In industry I have made this my profession. As business manager first for a plant and then globally, or as quality and EHS manager for large, globally operating units.
During my time in service and as a quality and EHS manager, I have internalized service and consulting. I enjoy my contribution when business and processes are running. As a business manager, I have dealt with all the processes of a product, project and service business. I can therefore advise companies in general, but I would like to highlight a few core issues here: Project management, process management, management system, organization, quality management, occupational safety, employee participation. I have moved primarily in the metal and electrical industry, internationally.
My aim is to find pragmatic and sustainable solutions and implement them consistently.
