Living quality at TQ

Bringing quality to life

True to the motto "Living quality", our quality management system is supported and implemented by all employees. Their supervisors promote aware for quality and environmental issues in regularly scheduled quality management training sessions. New employees are comprehensively instructed and trained in our quality management system. In addition, all employees make a personal commitment to observe the applicable requirements for quality, environmental protection and occupational safety, and to implement them in their daily work. They confirm this by signing a declaration of commitment to quality management.

Zero-error strategy

We pursue a zero-error strategy and focus on error avoidance before error correction. Checks at the end of a creation process can only detect errors. Capable processes, on the other hand, prevent their emergence. We therefore focus on systematic quality planning in advance, and strive to design capable processes characterized by continuous process and quality monitoring as well as fast and effective quality control loops in all phases of product development and in all areas of our company.
