The objective of this study is to investigate the perceptions of Greek managers towards competitive advantages in case of Greek food manufacturing industry. According Porter: "there are many sources of competitive advantage: making the highest-quality product, providing superior customer service, achieving lower costs than rivals, having a more convenient geographic location, designing a product that performs better than competing brands, making a more reliable and longer-lasting product, and providing buyers more value for the money. To succeed in building a competitive advantage, a firm must try to provide what buyers will perceive as "superior value"-either a good product at a low price or a "better" product that is worth paying more for". In order to achieve the above research aims, we administered a survey to 161 Greek managers of Greek food manufacturing firms, during the period January-September 2014. According to our results making the highest-quality product, designing new products and creating unique value for customers, having a more convenient geographic location and having advantage of production specialization are the main sources of Greek food and beverage firms' competitive advantage. Implications for research and practice are discussed.
