Procedures to demonstrate compliance with certain quality standards for products and services and their respective manufacturing processes. After successful testing, a certificate is issued, often for a limited period of time. This certifies that a company has a quality management system in accordance with the standards and a so-called "quality manual" in which the steps necessary for a repeatable and testable quality of products are described. The company to be certified describes which steps in (planning and) production are used to ensure the quality of the company's products in a traceable manner. This process is checked in a so-called "auditing" by a publicly recognized expert institution (e.g. TüV). The process also includes regular internal audits by our own employees as well as regular external audits by the institution that issued the certificate.
In the audits, detected deviations from the procedures of the quality handbook or deviations from newer standard requirements are documented in writing and recorded with so-called "breakpoints" (leads to withdrawal of the certificate if no improvement is made) or "observation points" (leads to a short-term re-examination). The audit reports are presented to the top management of a company. Many wineries also already have such certificates. A globally recognized system/certificate is the ISO 9000 series of standards. For the certification of organic farms in viticulture there are separate inspection bodies; see in this regard under Organic inspection body Austria and Organic inspection body (Germany) as well as under Organic associations.
