The variety of quality systems is a very important and an actual theme in the agri-food sector. These quality systems are only partly acknowledged by different quality standard organizations, but customers within the supply chain demand them. Enterprises, which supply different customers and export abroad this, face the problem that they have to deal with several standards and implement them within the enterprise as well as take part in several systems audits and certifications. The economic problem consists of determining the most efficient introduction of a quality system or a combination of quality systems in the enterprise. The emphasis of the work lies in the development of a framework for the benchmarking of quality systems at all stages of the agri-food production and an allocation and operationalisation of cost and benefit categories. A concept including the database “QualintSys” was developed during a PhD-thesis to estimate the costs and benefits of quality systems.
