"My customers manufacture safety-critical products, so there must be no failures: for more than 20 years, I have been protecting complex, electromechanical systems and IT applications from errors through structured requirements management and validated QA and test procedures with a forensic claim.
Quality is also my top priority in development, integration, and production processes: I enable manufacturers and suppliers to do this methodically and by acting on their own - with great success, especially in recovery projects."

Main focus
  • Capture and translation of functional and safety-critical system requirements into standardized architecture and design descriptions
  • Development, optimization, and realignment of processes in requirements and quality management as well as in the validation of systems   
  • Evaluation of requirements changes and design decisions with the assurance of requirements traceability
