Quality
is a continuous process
Or to put it another way: it's a never-ending process. An infinite cycle of testing, analysing, understanding, learning, optimising, and documenting. That's life. Our suppliers also support us with this process, as it's the only way to make quality management work for reliable switching devices. We believe in the zero-fault principle, coaching and training our team accordingly.
