Abstract
A major commitment and objective in the conditions of a market economy is to improve the
quality of production, with a special emphasis on increasing the efficiency of economic activity to meet
the production and consumption requirements. A permanent competition on both domestic and international markets has challenged companies to continuously ensure the high quality of their products, in order to meet social needs. The advantages from improving the commodities quality are reflected in an increased labour productivity, reduced production costs, increased profitability. Currently, many companies are particularly interested in the quality assurance models as proposed by international standards of ISO 9000, ISO 14000, ISO 22000, OSHAH 18000, etc. Some of these companies have already a certified quality management system based on these standards. They consider that the quality
system certification has a positive impact on business performance, acknowledging at the same time, the far-reaching importance of continuous improvement and implementation of this system, the principles of total quality management to ensure a successful performance in the competition.
