Quality is a “strategic weapon” for gaining an upper hand in the competition game in today’s world market. In the paper is debated about the role of quality as one of the fundamental factors of competitiveness on the world market. Quality control envelopes systematic use of different methods, guidelines, techniques, and tools, so that it can through high quality products and processes, meet the requirements of the consumers and achieve a competitive advantage that leads to business success. Business excellence becomes the strongest tool for achieving an advantage over the competition; many companies around the world have recognized this. Also important other than quality control is the design of the product. The design represents an element of differentiation as opposed to the products of the competition, in that way it becomes an significant source of gaining and sustaining the competitive advantage on the market. The importance of design control can be seen in that the design enters very often too late in the process of developing the new product due to that its meaning and potential remain neglected. The market research is a crucial process which needs to be implemented so that the habits and needs of the consumer are met, or rather so that an adequate product can be presented to the targeted consumers. This is not just about the quality of the product but also about the design, shape of the packaging which suits the buyer best. The last part of the paper is a example that in a clear way shows that proper quality and design control of the product is a significant competitive advantage on the market, which is being continuously researched and to which changes the company needs to adapt.
