The seventh principle of quality assurance is that the effectiveness of decisions taken depends on the state of
information support of the executive staff; therefore, in order to improve the products quality and the overall
performance of agro-industrial companies, the decisions should be based on objective, reliable, and relevant
facts.
The eighth principle of quality assurance is that the quality of products of agro-industrial companies depends on
the efficiency of interaction with suppliers. Therefore, agro-industrial companies focusing on improving the
quality of their products must build mutually beneficial relationships with suppliers.
The above principles of quality management (business processes and products manufacture organization) at
agro-industrial companies can be practically implemented as separate models used in national systems of
business management. Perhaps, each national socioeconomic system has its own model of quality management
and model of quality assurance of production and sales. Therefore, we can identify about ten national quality
models, including those well-functioning in the agro-industrial production area. However, many models are
duplicates or replications of each other. Therefore, we are going to review briefly the national models of quality
management: the Japanese, American, and European models.
