Unfortunately, nothing in this world is absolutely reliable…

…nevertheless, government supervision by the Federal Audit Oversight Authority (FAOA) and ISO certification does ensure a very high level of reliability.

Reliability is a key aspect of the high standards we set, and we have always accorded it the highest priority. Since 1997, we have been supported by a process-oriented quality assurance system. This system is recertified once every three years.


Here are the cornerstones of our quality policy:

  • Optimal customer benefit
  • Punctual compliance with deadlines
  • Efficient service provision
  • Correctness - in form as well as substance


Although our reliability is attested by certificates, we also endeavour to turn it into a living reality, day after day - we practice it in every detail and we accept no compromises in this regard.
