Nowadays, a more and more overwhelming role comes to global performance considering the intense competition at every market level. The competition law governs any conducted activity, thus the weakest, without the capacity of adaptability being removed from the competition,also economic,social and environmental changes which, at a global level, led to changing the way of thinking and conducting the global economic activities . At present, performance plays a fundamental role in the survival of the entities found in a permanent adaptation to the market demands by implementing new and successful management strategies. These strategies must cope with the elements specific to contemporary economy, meaning a competitive, unstable and turbulent environment and, under these circumstances, viability of economic agents cannot be achieved without talking about performance. Modern economic entities must cope with the demands of the new global economy, such as global economic crises, economic liberalization, high growing pace of competition, so that they can achieve the predetermined objectives, having the maximum of effects with the minimum of effort, but at the same time one should not neglect the social and environmental factors, directly or indirectly involved in conducting the activity. In the conditions of an environment which denotes less stability, the entities must be capable of making strategical decisions necessary for maintaining a balance and for being able to address and implement srateies for future, strategies which allow maintaining the organisation healthcare unaltered. Thus, we cannot bring into discussion the competitiveness of an entity in the conditions of a turbulent, fluctuating and especially competitive environment without talking about performance. This scientific approach has started from the premise that any economic entity has the goal of getting performance in conducting the activity. Thus, we have tried to get inside the problems of defining the concept of performance, starting from its beginnings until present, following the path taken by this concept from defining it according to a series of criteria such as: profitability,productivity, flexibility, adaptability, growth, to defining it as the level of achieving the organizational objectives; to assessing it according to productivity and efficacy of the economic entity; to its contemporary approach as the creation of value. Moreover, we are trying the defining of performance according to efficiency, efficacy and economies. As a result, being performant means combining all three variables, their combination reflecting the level of performance of an entity.
