In order to incorporate a true quality standard the quality management department of HAUPA decided at a very early stage to apply for ISO 9002 (at present DIN EN ISO 9001) certification, which controls and covers the complete internal working and monitoring procedures. From goods receipt to dispatch - all working processes are carried out according to defined procedures. All HAUPA employees receive regular training in order to comply with these standards and to encourage them to actively suggest ways of improving the processes. Special, so-called QMB employees analyse modified structures and integrate these into the defined standards. Independent auditors carry out audits at regular intervals to ensure compliance.
